It’s one thing to enjoy the look or scent of a plant and its flowers; it’s a bonus when the plant rewards the gardener with other uses. And to me, any plant that attracts pollinators and people is a useful one. Some plants do more, however, doubling as edible, decorative or medicinal plants for the home. Here are five plants with home uses that also survive low-water or drought conditions once established.
Lavender (lavandula) seems to be tops on any plant list I compose. I’ve yet to meet anyone who doesn’t care for the scent, and bees and butterflies flock to the flower stems. And the flowers – you can cut them for arrangements, dry them to make gifts and even use buds in recipes. Lavender is touted for its soothing qualities for skin and stress, as well as its aroma. The plants are easy to care for in a low-water garden. Simply give them well-draining soil so the roots dry between rain or watering. Harvest the first flush of flower stalks and you’ll likely have another bloom in late summer. Otherwise, trim only to shape in spring.
Another favorite low-water herb is thyme. Just touching it gives your hand a salty, earthy scent. You can cut entire stalks in the fall for drying, or cut a fresh sprig for flavoring poultry. It’s an excellent herb for flavoring vegetables with strong flavors, such as cabbage. Tiny purple flowers emerge on longer stems that haven’t been harvested, attracting bees and adding delicate color to a xeric garden. German thyme is hardy in zones 5 through 9, but lemon thyme needs a little more heat (zones 7 through 9). Just give thyme plenty of sun and well-drained soil and it will spread, creating a low bushy appearance in the garden.
Sea holly (Eryngium amethystinum) has a thistle-like appearance to me. The drought-tolerant flower is a perfect choice for rock gardens, or even sandy beach gardens. That’s because it loves hot, dry conditions. Big Blue reaches heights or nearly three feet. The stunning silver-blue flowers are spiny in texture. Use sea holly indoors by cutting a few flower stalks to include in arrangements. Not many other cut flowers have their color, texture or unique look. Sea holly grows in zones 2 through 10.
Got sunburn? Fresh gel from your own aloe vera plant (Aloe barbadensis) can provide soothing relief for burns and skin rashes. Of course, sunburns are more likely to occur in areas where you can grow aloe vera plants outside, like Maui, where we used aloe to soothe our tourist “color.” So, it’s an outside plant only in about zone 10B, or where night temperatures go no lower than 40 degrees F. Aloe vera also needs well-draining, even dry soil. The plant stores water in its fleshy leaves, which makes the well-known gel. If you’re in most zones, you can grow aloe vera as a houseplant and summer outdoor visitor. When you need to extract gel, you can use simple kitchen items. Here’s an article explaining how to get gel from aloe leaves.
Growing nut and fruit trees for shade and food is a smart xeric gardening strategy. Of course, you have to pick the right tree or shrub. The pineapple guava (Feijoa or Acca sellowiana) is an excellent example of a tree that bears juicy, full fruits but with less water than some fruit trees. These aren’t like truly tropical guavas, but have a taste that resembles a mix of pear and pineapple. The plant is drought tolerant but a little more water ensures late summer to fall fruit. And even if they don’t fruit much, the gorgeous white and red flowers look good enough to eat. It’s too cold in New Mexico, but southern California gardeners can enjoy the plant and its fruit. In fact, we spotted a guava in the lawn of a Pasadena home. I was too busy being jealous to take a photo. Here’s a photo and more information on the plant from Monrovia.
I’ve been thinking about weeds and wildflowers a lot this week, probably because I spotted my first field bindweed in a gravel path. But it’s also because I’m thinking about spring flowers, pollinators and soil.
In past posts, I’ve described the stages of “acceptance” we’ve gone through with the yellow flowers that pretty much blankets our property. In brief: The plants are similar (and related) to wild alyssum. Technically, they are a type of Physaria, also called twinpod or bladderpod. The plant is good because it attracts bees – hundreds of them. And it’s pretty, creating a sort of spring meadow. But it’s bad too. With a deep tap root, the weed/wildflower, (a member of the Brassica, or mustard, family) likely steals water and some nutrients from the grass or garden plants.
Following an excellent Twitter chat on nitrogen fixers (#groundchat led by @CristinaGardens; also on Facebook), I decided to check again whether this mustard/alyssum helps or hurts soil. It turns out that yellow alyssum does not fix nitrogen, but has a role in recycling the nutrient. It can help smother weeds, but then is it smothering or delaying grass? Yes, it threatens native grasses, according to the Colorado State extension office. And in a xeric garden, I don’t want a plant that robs vegetables or perennials of precious water.
Then I found an article saying that the long tap roots on plants help till or break up soil with their long taproots. They also can bring nitrogen back up to the surface, or at least help conserve it in soil. Shouldn’t that be good for grass? And many varieties of Phyaria are endangered. Not so much in our neighborhood…
When the roots decompose, they add organic matter. So, I’m back to accepting alyssum/physarium for these bonus qualities, but mostly because we’ll never win.
Let’s go back to the nitrogen fixers for a minute. Plants need nitrogen to survive. How much a given plant needs varies, but it’s safe to say that nitrogen is an essential plant nutrient. Many gardeners who use fertilizers know this; the N in formulas represents nitrogen. But why apply a synthetic fertilizer to crops or a garden when you can harvest nitrogen with plants that do the work? It’s the organic approach to soil improvement that’s really catching on with farmers. Hurrah!
Examples of nitrogen fixers are hairy vetch, annual wheat grass or ryegrass, and legumes, including clover. Wait, what? I’ve always considered clover invasive. And during the chat, I received an excellent link to an article about sweet clover. Looks like clover is to many gardeners and farmers what the mustard family is to us – good or bad, invasive or not. It all depends on your conditions. Further, conditions that favor a particular weed or wildflower can change slightly from one year to the next. Red clover is a potential nitrogen fixer in New Mexico.
And that’s why it’s all relative. I love learning from social media, and learned a lot the other day. But when choosing plants, especially for a large area such as a meadow or field, it’s always best to check with local extension agents or their publications. Otherwise, gardeners in New Mexico would never plant butterfly bush (Buddleia), which is not invasive here, and a gorgeous xeric choice. And they might go a little wild with mustard natives or horehound, which are terrific additions to gardens in some areas, but can take over a New Mexico lawn.
Rosemary (Rosmarinus officinalis) is the perfect low-water herb, and for that matter a perfect xeric ornamental. This year, we have two we keep as ornamentals and allow to bloom, and two for culinary use in containers, because I have a hoarder-like fear of running out of rosemary.
I understand that rosemary (and lavender, my other favorite low-water herb) can be somewhat difficult to grow in wetter climates. Well, let us desert dwellers have something, OK? We can’t in all good consciousness, or with much success, have tropical bloomers. And even having more than one hybrid rose seems wrong in areas with so little annual rainfall.
That’s exactly why rosemary does so well here. Once established, the plant thrives with less water. Depending on the variety, rosemary is hardy in zones 8 through 10. A variety called R. officinalis ‘Arp” is hardy to zone 6, however, and to zone 5 with some effort from the home gardener.
And I mean just a little effort. It’s generally easier to overwinter rosemary outside than indoors. Here are a few ways to push the zone a bit on rosemary, and my tip for keeping rosemary (and lavender) healthy through winter.
Plant your rosemary in full sun if possible, especially considering the sun’s winter path.
Use rocks or a wall to reflect heat in winter and help keep your rosemary warm as temperatures drop. You can also add some gravel mulch, as long as it doesn’t enclose the plant and retain water.
Use a container for rosemary and move the container to a protected, warm location (even though it’s still outdoors). I have one container on the southwest side of my patio for easy access and another against a southern wall that gets full sun all day in the winter.
Harvest! Harvest some rosemary for culinary use well before the first frost so that the plant is healthy and not blooming. Or if your plant is ornamental, a few blooms are fine, as long as you avoid pruning, and especially cutting into woody stems, anytime from four weeks before the first frost until early spring.
Water sparingly all year, but especially in winter when the plant dries more slowly. Wet feet cause root rot on rosemary and lavender plants.
And here’s my best tip for keeping rosemary happy and healthy in the winter! You know when you can’t wait to get outside and play after a snowfall? You take the kids, the dogs, the camera, your companion of choice…outside to enjoy the snow. Stop for a second and head straight for your rosemary in the garden or container. Carefully brush as much snow off of the plant as you can, especially over the center, main branches. We nearly lost a beautiful trailing rosemary bush several years ago before I knew how important it was to do this. The slow melting of snow amounts to setting your drip hose to run on the rosemary for days. It can destroy part or all of the plant.
This week, I used my bare hand (until I couldn’t feel my fingers) and then a soft broom to brush off all of my rosemary and lavender plants while the snow was still flaky. And yes, I pulled out my camera…
In the past week, I’ve heard several friends or family members say that they can’t grow plants, that they kill everything they try to grow, etc. I’m here to tell you that every gardener has killed a plant. And if there is anyone out there who can prove otherwise, I’ll send them a free succulent. We have plenty to spare. Just don’t tell my husband.
The seasoned gardener will blame the deer that ate/trampled the day lilies or the bad, strange weather the past year (read nearly any of my blog posts) or grasshoppers and other insects that brought damage and dreaded disease. You know, these seasoned gardeners aren’t really lying. The truth is that all anyone can do is start with the healthiest plant possible, place it in the best possible environment and care for it according to the plant’s needs and the environment in which it lives. If it doesn’t work, we learn from it and try again, sometimes with another plant or another place. And if you get really fed up, you can always switch environments!
We happen to love our environment, and I know there are many more hostile than ours. No matter where you live and grow, gardening is trial and error. And like any hobby or DIY project, preparation and a little upfront learning can increase your chance of success, even in a hostile setting. Here are a few problems we face in ours, along with tips to keep from giving up.
Drought and water use. When you “go with the flow,” so to speak in low-water gardening, you take what nature delivers. That means supplementing new plantings with water until they’re established, even watering xeric plants more than suggested for the first year or so. We use rainwater as much as possible, and since our established plants generally need little to no irrigation, we can use well water sparingly as needed. A bigger problem can be too much water. And I think new gardeners, or at least gardeners adjusting to growing xeric plants, tend to overwater drought-tolerant plants for the duration. It’s also instinct to assume when a plant wilts that it needs water, when the cause might be something else. Sometimes, Mother Nature overwaters and having healthy plants helps them ride out the storm.
Never Give-up Tips: Avoid the temptation to overwater. Make sure low-water plants get a good start, especially by planting them in well-draining soil with plenty of organic matter.
Climate. Nature also can deliver water or temperature in strange patterns. This year, we had more than a week of clouds, cool temperatures and wet days. Our plants got confused, and sometimes climate conditions that are unnatural to native plants can cause stress and disease. At other times, it keeps them blooming later than normal, which is a good thing. Using microclimates, even temporary ones, can help plants weather the goofy weather. For example, I planted my chile and bell peppers at the same time as last year, but the weather was cooler than normal right after I planted. I’ll admit that our seedlings were a little weak, too, so that’s a lesson learned. But I should have put something over or around them to warm them up a notch. A few of them never thrived.
Never Give-up Tips: Know your plants’ zones and sun requirements and follow them when planting, remembering that trees leaf out and grow! And try an edible or annual in a different spot next year or move an established perennial.
Gophers. I’ll include all underground critters, such as moles, prairie dogs and ground squirrels in this one. For us, gophers rank up there as enemy no. 1. You can’t even say they’re cute, because for one, you really never see them. They do their damage mostly at night and I have only seen one pop up as it worked to open a hole in our brand new lavender bed, after chewing up the roots of one of the brand new lavender plants, of course. Some will say they improve the soil. I say they destroy plants. Our tally in a few years includes an Echinacea, a primrose, an ornamental grass, two lavender plants and at least one dwarf apple tree. The newer and more vulnerable the plant, the more they seem to love it.
Never Give-up Tips: The only method that works for keeping gophers away from a vegetable or ornamental garden is burying metal barriers 24 inches down to surround the entire garden or using raised beds such as metal troughs. Of course, container gardening also works. As for control, that’s a post, or two, or three, of its own.
Deer. Deer are cute and we try to work with them. Our property has only pipe fencing, which the deer and elk can jump over or wind their way through easily. Many of our ornamental plants are unattractive to deer, and we fence those that they enjoy munching on, at least until the plants are large enough to survive the meal. We’ve learned the hard way on a few plants. For example, I didn’t know that deer enjoy the flavor of a spineless prickly pear cactus until we lost an entire pad! They were nice enough to just step on the other one. Deer do draw the line at spiny prickly pear in case you’re wondering.
Never Give-up Tips: It’s easy to search online for lists of plants that deer prefer or avoid, and fencing really is the only deterrent that works. I have used soap shavings (strong-smelling ones) hanging around my unfenced tomato plants with some success, but only in summer when they have a buffet of choices.
Insects. I don’t much care for bugs, and am learning all I can about the bad ones. We use integrated pest management, because the last thing we want to do is kill bees, wasps, ladybugs and other beneficial insects. Our fruit-set rates were incredible for this summer’s vegetables, and I thank our pollinators. But our plants and our feet are under constant attack. Ants have taken over our orchard and we caught some carrying off fall carrot seeds the other day. This is a problem we have to work on, but also accept as part of gardening. And we will continue to do what we can to attract pollinators.
Never Give-up Tips: Hand-pick known criminals such as tomato hornworms or cucumber beetles after you’ve identified them. And spray plants with water for offenders such as aphids. Spraying pesticides, even organic ones, can kill beneficial insects that help control the bad bugs. We plan to add row-cover cloth over more seedlings this year until the plants flower to help control grasshoppers and other bugs.
Weeds. It’s so hard to pick a favorite problem! Or least favorite, I should say. With four acres and a couple of garden areas, we seem to spend more time dealing with weeds than growing. I’m not of the mindset that weeds are good, because I think they harbor pests and critters if left to their own devices. Many also compete for water resources. We are relaxing our rules a bit, however, having decided which invasive plants we can take out of the weed column and which to leave there. And since we know we can’t remove them from every spot, we’re eliminating weeds where we can and turning our attention to prevention.
Never Give-up Tips: Use organic practices such as thick mulch and plastic or tarps in vegetable garden prep to block sun and water from weeds and thus prevent them. Hand-pull or hoe around plants to prevent weeds such as field bindweed from choking plants or stealing their water. Just because a thistle has a pretty flower doesn’t mean you should let it go to seed if it’s invasive in your region.
Xeriscaping has become more of a mandate in many Southwestern communities, and it’s too bad that it’s come to that. But with long-term drought and overpopulation in concentrated urban areas, it’s no wonder that water resources are scarce.
As I’ve said for a few years on this blog, drought is nothing new to New Mexicans, and many leaders of low-water gardening and planting hail from Colorado and New Mexico. That doesn’t mean everybody gets it, but there are plenty of examples of gorgeous front and back yard landscapes that use little to no irrigation but have curb appeal and bring joy to home gardeners and guests.
One of my biggest concerns about water restrictions imposed on residents of Western states is that homeowners and business owners will react to the extreme, going from a complete high-water turf lawn to all-gravel landscapes. I’ve ranted here and plenty of other places on this blog about what this move does to existing trees, home energy use and how it’s just plain ugly.
Here’s a summary of six strategies for planning an attractive and effective waterwise landscape that includes some living plants and joy without blowing your budget or your mind.
1. Start with xeric zones. The concept of simple xeriscaping zones around your home makes planning easier. The point is to place your gravel and most drought-tolerant plants the furthest from your home. Putting a few plants that need a little more water, or having some turf for the dogs, kids or green that you love is OK, as long as you keep it in moderation and close to the house. This helps keep your house cooler, gives you and your family a nice place to gather and can even help keep shade trees alive. Those are waterwise and energy-saving strategies and can help form the basis for your plan.
2. Keep the right type and amount of turf. Unless you have reasons beyond water savings, you don’t have to eliminate turf altogether. Just switch out the type and size of your grass area. Take the grass out of your arid zone, and replace grass in small portions of the transition or mini-oasis zones (areas closer to the house) with a native, drought-tolerant variety. Your local nursery should have native or hybrid grasses in seed, sod or plugs that grow in your area with little to no watering once established.
3. Take a tip from permaculture. Approach your new landscape holistically, creating a design that’s self-sustaining. For example, divert rainwater from your roof to water a shade tree or create a small rain garden or bioswale in an area that always pools with mud or water after a hard rain. Use leaves from the shade tree for compost or simply rake them up to mulch a plant. Grow edibles as ornamentals in the sunny spot once taken up by grass. Include some xeric plants that attract pollinators to help ensure good fruit production on your new edibles. The photo at the top of this post shows a few of these principles, but we’re working on incorporating more.
4. Level land with burms, steps or terraces. One of the biggest wasters of sprinkler water, aside from evaporation, is runoff. If your landscape has any slope at all, finding a way to control that slope can save water immediately. For example, when we added to our patio, we messed with the water runoff and it affected nearby established plants. They’re not as healthy now because they got too much water. So we plan to try a combination of a bioswale and burm to relocate the low-water plants and divert some of the water. Burms are usually rounded shelves or bumps, with a more natural look. Steps can give you access to an area and great placement for xeric plants and ornamental grasses. Terracing shores up dirt and water and provides excellent opportunities for landscape palettes and sectioning off beds. Look for lots of ideas online and by driving around your neighborhood, and get help from a landscape designer and contractor if the job is too much for you.
5. Use indoor design principles. If gardening overwhelms you, or you don’t know much about plants, it shouldn’t stop you from creating some curb appeal in a new low-water landscape. Many of the same principles apply to outdoor design as indoor – color, texture, height and shape. Terraces or burms can help, but even if you have a flat yard, you can start with an existing or new tree for height and take it from there. Just look at a plant’s tag or seek advice from a local master gardener, favorite local garden author, or favorite garden blogger. Look at the plant’s mature height, spread, flower color and a photo of the foliage.
6. Feature native plants. The surest road to success with low-water landscaping is to feature plants native to your area or to areas with the same climate zones. For example, California gardeners are expanding their plant choices with low-water natives from other Mediterranean countries such as South Africa and Western Australia. Once a native plant is established, usually after a year, it should make it through your climate extremes with no extra work on your part. Native plants have adapted to the environment. And although some need pruning, deadheading and sometimes a little bit of drip irrigation, many need nothing but your attention, which you give them when you walk through or sit among the plants. We have a huge rock garden, and we never water most of the plants, or give them one drink after spring pruning if we’ve had no rain. Native annuals and wildflowers are particularly beneficial, and some homeowners reverse their xeric zones to create meadows and completely natural areas along the edges of their properties.
Finally, the best strategy is to take it slowly, steadily and with moderation. I fear that too many people will react by letting their lawns die or by pulling them up and replacing them with landscape plastic and gravel. My hope is that I will continue to see colorful native landscapes throughout the West filled with edibles, blooms, evergreen foliage and low-water shade trees, and dotted with touches of native grasses where kids and pets can run around and birds can peck for seeds and earthworms. Is that too much to ask?
It’s one of the easiest plants to grow, pretty much resistant to disease and a sun lover. I think what I love the most about cucumbers compared with some vegetables is that the fruit tends to mature pretty rapidly and in stages. I like that a lot better than having no fresh tomatoes 11 months out of the year, and then having such a bounty that you have to take a bag of them to work to make sure none go to waste. I’ve planted four cucumber plants in succession – two at a time several weeks apart.
Cucumbers usually grow best directly from seed. It’s possible to transplant seedlings purchased or grown indoors, but cucumbers don’t do well if their roots are disturbed. Because cucumbers need plenty of water, make sure you’ve prepped your soil with lots of organic matter before planting. That will help it retain water. I read on the package to plant seeds in a mound; that didn’t work for me. The cause might have been cool temperatures, but I think it also had to do with our low humidity. We always prefer wells to hold water in. The second planting was much more successful; I had to thin the seedlings.
Plant cucumbers where they will get full sun and where you can help them climb off the ground with a fence or trellis. If you can’t get them near a trellis, use a tomato cage or rig your own system. This help keep fruits from getting bent under heavy vines and keeps them from taking over your garden. Most importantly, growing vertically gives your plants plenty of air circulation, improving plant health and fruit production. There are a few bush varieties that grow in containers if you have no way to help cucumbers trellis upward.
Troubleshooting cucumber problems
When seedlings fail, the ground might not be warm enough. Just try again as temperatures – and soil – warm up. Other than that, you’ll have little to no trouble with cucumbers. If your plant flowers but fails to set fruit, the likely problem is lack of pollinators. You need some bees. All cucumber plants should have male flowers and female flowers. They look pretty much the same, except for the small fruit that’s located just behind the female blossom. Once the bees visit the male flower and drop pollen into the female flower, the fun begins.
I recommend cutting cucumbers when they are relatively small for better flavor. Let them get too large and they have big seeds and slightly bitter flavor. Plus, leaving them on the vine sends a signal to the plant that its work is done, and the plant begins to wind down the production process. As I said, planting a few cucumber plants several weeks apart gives you a steady supply all year. Unlike zucchini, cucumber tends to give you a more steady, manageable supply of fruit. In most zones, you can sow seeds as late as July.
Bugs on plants are more than a nuisance. They damage plants by sucking out sap, destroying leaves and transmitting diseases. I’m all for a balanced ecosystem, and I realize bugs gotta eat too, but there’s a point at which I have to choose between the bug and being able to eat the cucumbers I have spent time and precious water nurturing from seed. I might not be smarter, but I’m bigger and I have tools and creativity.
For many years in the past, home gardeners like us relied on chemicals to kill a bug at the first sign of trouble, and I’m so glad that the concept of integrated pest management, or IPM, has replaced that approach for so many people who care about the food they eat, the environment and preserving beneficial insects.
Let’s break down a rather fancy term into the basics: start with the least harmful control. It’s really the same as prevention in medicine. Ward off a disease as your first choice instead of having to go through treatment. Here are the basic steps:
1. Start with healthy plants and good cultural management. This is the most important step to try to prevent insects in any yard or garden. First and foremost, plant native plants. I’ll never stop repeating this mantra. When you include plants adapted to your environment, they’re less likely to get stressed. There’s lots of research on the plant stress hypothesis because I guess some people disagree with it. But prevailing thought seems to be that plants stressed by drought or other conditions are more vulnerable to bug infestations and damage. It makes sense, and it’s still better to keep plants healthy anyway for flower or fruit production. Be sure to rotate crops, plant a variety of plants, and place plants in the right conditions based on shade or sun requirements, for example.
2. Keep bugs away by weeding as much as possible and cleaning up debris to prevent hiding places. And cover seedlings with tunnels and row covers (with no holes) to keep bugs off while the plants are young and more vulnerable. Make sure plants are not too close together so they have airflow and can dry out as needed. Use mulch to cool roots and hold in water and compost to enrich soil. If one plant gets a disease, remove it from your garden and throw it out. Don’t lay it near the garden or compost it.
3. Hand pick bugs that appear if you can. This is not always easy, but if I can touch bugs, anyone can. Home gardeners who visit their garden regularly to water, deadhead flowers and check or harvest vegetables should inspect for bugs, especially in the morning. A major advantage of handpicking is that you can pick just the bad insects, causing no harm to beneficial bugs on your plants, who are there helping in your cause. See my Resources page for a few links to articles or photos that help identify beneficial insects. And here’s what I do when I pick off the little bug – throw it in a container of dish soap and water. I like to reuse a plastic container with a flip lid each year for easy, one-handed entry. Last year, it was an empty sanitary wipe jar. This year, I had used nearly all of my taco spice mix from Costco. I put the rest in a plastic zipped bag and had an instant bug bath. A blister bug infestation at our community garden one year had Tim and I doing a “swipe and boot stomp” method because those monsters bite and because of pure numbers. Our neighbor finally had to vacuum the potato plants.
4. When all else fails and you must use a pesticide, there are several organic choices. It’s also important to know that although an insecticide is organic, it still can be harmful, especially to bees and other beneficial insects. The three we keep on hand are insecticidal soap, Neem oil and Diatomaceous earth. Still, it’s recommended only to use these products once you have identified the pest or really have to do so. For example, I can spray a plant with water first to stop aphids before resorting to soap. I encourage reading labels carefully for time from use to harvest for any edibles, for specific pests they destroy and for any cautions about other insects, pets or warnings.
Further, you can’t be perfect at IPM cultural practices, as hard as you try. For example, I’m pretty sure tomatoes are not native to my region. But I want a vegetable garden. I have to work harder to keep tomatoes healthy than I do the ornamentals (and weeds!) native to New Mexico. I also can’t control the weather. I’m certain many of our bug (and snail!) trouble occurred during frequent night rains and cool, cloudy days. Our plants aren’t adapted to that. Finally, we spend most of our time on weeds – mowing, pulling and preventing. But we can’t control all of the weeds, nor can we control what our neighbors do with weeds or chemicals.
What’s not to love about a plant named for the butterflies it attracts? The butterfly bush (Buddleia) has much more to offer as well. It also attracts bees and plenty of hummingbirds. The plant is a long-lasting perennial in several zones and it’s easy to care for.
To me, the buddleia is like a magical shrub. There’s something kind of free-flowing and natural to its shape, and to how rapidly it grows on its woody base. Despite its sometimes uneven appearance, the buddleia makes a perfect centerpiece or backdrop in a xeric garden. Ours sits in the center of a forefront bed, where we can watch hummingbirds and butterflies visit from our patio, but I have seen the attractive bush used well against walls and walkways throughout New Mexico.
There are many varieties of butterfly bush, and several colors of the showy flowers. A dwarf buddleia usually reaches about three to five feet in height, but the fountain buddleia grows up to 12 feet tall, is adapted to higher altitudes (above 6,500 feet) and has longer flower spikes than the typical six to eight inches. Most of the New Mexico buddleias bloom in variations of lavender, plum or purple. And I find the foliage attractive, having a kind of muted, silvery-green color and texture that brings to mind giant sage leaves.
Caring for Butterfly Bushes
Buddleia is a drought-tolerant plant that should only need supplemental watering until established or when temperatures are consistently above 85 degrees and, of course, rain is scarce. I seldom or never water mine except after cutting it back in late winter/early spring.
Though you don’t have to deadhead the blooms, you can trim off the seedheads once they’re spent to encourage new flowering. I usually don’t bother, as my plant seems to produce for most of the season. I just give mine that drastic haircut in late winter as soon as I see a little bit of new growth on the bottom stems; it shoots up in height as soon as temperatures warm.
Nearly every buddleia is hardy in zones 5a to 9, depending on the cultivar and the microclimate you place it in. I recommend talking with a nursery representative or a landscape designer before selecting a buddleia to make sure you choose the best size for your location and to see if it is native or at least noninvasive (sterile flowers).
Last week, I posted about the Million Pollinator Garden Challenge. If you haven’t registered your garden yet, this week is a great time to participate. June 15 through 21 marks National Pollinator Week!
And if you feel your garden doesn’t meet the criteria for a pollinator garden or need some help attracting pollinators and saving water at the same time, read on. I’ve got a list of low-water plants that attract bees in particular.
Let’s first review a few reasons you want bees. Their numbers are dwindling, and the more homeowners and businesses that plant gardens to attract and nourish bees, the more we keep bee populations going. In your own garden, bees pollinate more than two-thirds of your flowers and edibles. Apples, cherries, beans, and other healthy and delicious crops in your yard or local farms need bees to produce their fruit or at least lend a hand, and not just in the height of summer. Gardens that provide bee-loving flowers from early spring until late fall help keep local populations thriving.
Here are a few low-water plants bees love:
Bee balm (Monarda “Jacob Kline”). You can’t go wrong with a selection named for the insect. To encourage the large, red flowers, you might have to give it some extra water, however.
Apache plume (Fallugia paradoxa). I’ve mentioned native or wild roses before. The Apache plume is a member of the rose family, but is more shrubby, partially evergreen, native, forgiving to heavy trimming or shaping, and needs no water once established. Bees love the small white flowers.
Thyme. If you allow culinary herbs to flower, bees often go wild. We have thyme in our garden that flowered early this year and is a big attractor. When rosemary blooms, bees swarm all over it.
Sage. Bees also flock to culinary sage. I don’t mind letting some of my herbs flower because I have space. If your space is limited, you might want to cut herbs back (and use them in the kitchen). Pruning makes them healthier, as long as you don’t cut into the woody stems. I prefer to keep a few plants trimmed for culinary use, often in containers, and a few wilder for color (and pollinators). Other sages, such as salvia, also bring bees to your garden.
Onion (Allium) is a popular low-water edible that comes in an ornamental variety called Cokscrew blue twister that attracts bees with its pink flowers.
Pink lamb’s ear (Stachys lavandulifolius). A xeric wildflower that has fuzzy gray leaves and pink flowers to attract bees.
Catmint (Nepeta) has a bluish-purple flower and a strong scent. The low-growing plant can be invasive, however.
Alyssum. If you’ve read my past posts, I have bemoaned this invasive wildflower/weed. But I will say this much: Bees can’t get enough of the pungent blooms, and we probably fed enough honeybees from our yellow land alone in early spring to pollinate half of the desert Southwest!
Fruit trees also attract bees while flowering and there are plenty of vines and shrubs that draw bees to the garden. Carolina jessamine (Gelsemium sempervirens) is a low-water, fragrant choice and Coral honeysuckle (Lonicera semperivirens) uses little water and handles heat and cold. Be aware of vine and shrub spread when you place them, especially regarding be buzzing!
The number of honey bees and other pollinating insects is declining around the United States. Colony collapse disorder and other diseases, along with increased pesticide, use are likely culprits. What’s more, monarch butterfly populations have been declining by the millions!
On May 19, President Obama announced steps aimed at improving the health of pollinating insects. And in response, the National Pollinator Garden Network issued the Million Pollinator Garden Challenge. According to the network, pollinators help generate one out of three bites of food we eat each year. Planting plenty of trees and flowers that attract bees, butterflies, birds and bats can help improve pollinator health and populations.
The challenge calls on homeowners, businesses and communities to create and sustain gardens that attract pollinators. Let me just say that this is another concern I have about extreme xeriscaping, or a trend I see of replacing every bit of plant and lawn in a landscape with gravel. New Mexico, for one, is barren enough. And there are plenty of xeric plants that attract birds, bees and other insects and provide some color in the landscape.
According to the Million Pollinator Garden Challenge, a pollinator garden should:
Include plants that provide nectar and pollen sources.
Provide water for pollinators.
Be in a sunny location with some wind breaks.
Have large areas of pollinator-attracting plants that are native and noninvasive.
Include plants that bloom throughout the season.
If possible, eliminate pesticide use, and at least minimize pesticides.
And here are a few tips for meeting the challenge, or at least for making sure you have plenty of bees, butterflies and other pollinators in your garden:
Of course, including native, low-water plants is critical. Look for symbols in product catalogs or lists of xeric pollinators. And remember bees love herbs too. They buzz all around our thyme when it flowers, and there are roses and other flowering ornamentals pollinators love that need nothing but rainwater once established.
Some people avoid plants that attract bees because of possible stings, especially with children around. I have a few plants that attract seemingly hundreds, and one we walk past constantly. But if bees bother you, just place your pollinator plants where you can see them, but in a spot you seldom sit or walk by, and not where the kids’ soccer ball always ends up when they play in the back yard.
Providing water can be tough. Our birdbath dries up in a day or two, and I hate to refill it, knowing it will evaporate. But I can use rain water. The birds also gather on the top of our rain barrels, where the water sometimes pools. Butterflies need only a few drops in a tiny rock or plate.
Some native plants bloom continuously with no effort on your part. Look for those! An example is catmint (Nepeta). And create a dense grouping with a mix of colors and bloom times to attract pollinators, especially if you have limited space. A few annuals can provide blooms when perennials fade. We have cosmos that pop up late in summer and birds balance on the thin stalks, gathering seeds.
One of the great benefits of inviting pollinators with flowering plants is that they should make a side trip to your edibles. Don’t be afraid to plant some flowers near vegetables, as long as they don’t compete for sun and water or hide weeds.
If your roses or other plants get aphids, wash the tiny bugs off with a fine spray of water in the morning before turning to a pesticide; it’s just not necessary. Spray again in a few days if more return. And try to stick with pesticides on your edibles that are least harmful to honeybees, such as insecticidal soap.
