When you tour botanical gardens or private gardens, do you ever look up to see what’s above your head? Most of us plan our gardens while sitting on our back patio or strolling through its paths. Often, we choose plants simply because we see them at a nursery and love their flowers. There’s nothing wrong with that, but one day soon, take a look at your landscape from the point of entry, such as the gate to your backyard, and walk around, considering the overall look from ground level to tree canopy.
You might be pleasantly surprised, and you can add interest and beauty to your garden by considering what goes on over your head. I recently toured several gardens in the Denver area and noted use of arbors and other design elements to add height and 360-degree interest to landscapes. Here are a few examples.
Decks and Patios
Al you need are a few containers and some “engineering” skills to garden vertically, so to speak. Here are some of my favorite examples.
Arbors and Pergolas
Some plants are just born to trail up, down or around. With a well-placed arbor, you can add height, shapes, color and materials to your garden. Most of all, you can display some beautiful climbing plants that double as shade-makers.
Mix up Plant Heights
Finally, don’t be afraid to add tall trees or other natural elements right in the middle of your garden. I always worry I have to place the tallest plants in the back. But breaking the “rules” can be fun and a hit.
We are wrapping up a big project in our rock garden. It involved removing some lower beds and extending the raised beds out, bordered by a gabion wall. So, that meant having to dig up and transplant several favorite plants. After all, we needed to fill a lot of new planting area, and it’s always sad to lose a plant simply because of logistics.
So, Tim started digging up some plants last fall, when we began work on the new walls. He planted them in recycled nursery containers with a combination of potting mix and soil from where the plants were growing. When it became warm enough, we replanted them, helping to save a little money on filling our new beds and keeping some of our favorite plants going.
Plants That Naturalize
Many plants we grow in the Southwest re-seed (volunteers) or have spreading habits that make them easy to divide and move. Sometimes, a plant reproduces so easily, it becomes a problem. But conditions have to be just right for that, so I love this feature in a plant. After all, you can always transplant or gift one of your plants. Here are a few low-water plants we “saved” and replanted:
Salvia plants are related to mint, and some of them sprout new plants from seeds. We have a row of midnight blue salvia plants that kept producing “pups,” so we potted some up, transplanted some directly and gave some away. We’ve never purchased the plant; these all came from one that was here more than six years ago.
Likewise, we have a purple penstemon (Rocky Mountain penstemon, or Penstemon strictus) that Tim dug up from one that spread in some grounds he used to care for. We planted in at our last home and it spread a little more, so we brought a part of it here. We had to transplant it to build our new bed, and now have at least six plants from the one he dug up about eight years ago.
Blanket flower (Gaillardia) is a wonderful magnet for bees and a great xeric perennial flower. It can spread from seed; we also saved and moved a few to our new beds. They have perked up and are doing well.
Of course, iris reproduce like rabbits and they’re easy to transplant. We also moved some daylilies and split up a Kniphofia (red hot poker) to help fill our new beds. The jury still is out on when the lilies and red hot pokers will bloom, since we moved them when we had to, not necessarily at the best time for the plants.
This native plant is one of several that starts volunteer seedlings around our garden. Although some might see this as a drawback, we welcome the seedlings. If we can’t move them, we always can pull them up if in the way of another plant.
Herbal thyme is one of my favorite plants. The low-water herb does triple duty: it looks and smells great in the garden, it has delicate flowers that bees love, and it tastes great! We have let some plants spread and transplanted others.
Threadgrass is my new favorite low-water plant. It is easy to care for, and produces lots of little seedlings that are easy to spot and tell from other grasses or weeds. Just dig it up and move it to another spot.
A Few Tips for Replanting
Some of our success with volunteers certainly comes from letting plants go to seed. That can be a bad idea if they become invasive and crowd out other plants or if your front garden looks too unkempt through fall and winter. But re-seeders can feed birds in fall and give you new plants to enjoy in spring.
Remember, if you are planting or dividing a plant, even a xeric one, it will need extra water for at least a few weeks while it gets used to its new home. And it needs a little extra water and care in its first year of life.
Check your favorite local and regional books or with local independent nursery staff to find out plants that re-seed in your area without taking over.
Of course, you also can keep an eye out for plants that re-seed. Nature often puts them in the perfect place, which also gives your xeric garden a more natural look.
Finally, we are guilty of planting one of each plant we like. I’ve since seen enough gardens in which repetition of plants actually looks more natural and striking than stuffing in as many different plants as we can. So, don’t be afraid to plant three or more of the same plant!
Each year, Pantone, which is the universal standard for color in printing and graphic design, selects a Pantone Color of the Year. The 2019 color is Living Coral. The color (Pantone 16-1546) is named for the coral that thrives beneath the surface of the sea and the warm pinkish-peach tone represents the natural warmth and comfort of a coral reef. One of the reasons for its selection is a trend noted by Pantone researchers of companies and designers using the color in branding efforts.
Living Coral in Nature
Often, garden writers plant sellers highlight bright purples, reds and yellows. They make for stunning photos or turning heads when driving by a landscape. But I’ve always loved this more subtle color. It’s not as common in native plants as are many other bloom colors. But the hint of pink, peach and oranges with golden tones beneath makes for some attractive combinations in the garden.
With undertones of peach, coral complements blues in the garden and the pinker tones look amazing with green. Softer hues of coral stand out with bright yellows. Aside from living coral in the sea, which most of us never will see in person, you can find the color in natural items like peach blooms and peels or fresh salmon. It’s also a captivating color in the flowers of the plants below (click any thumbnail to scroll the gallery).

If your garden, houseplants or a favorite container lack coral color, think about adding some in its honorary year!
No, I’m not kidding. There is a flower that grows well in the Southwest that smells like chocolate. It’s like my two favorite things in one pretty package! Chocolate flower (Berlanderia lyrata) casts its rich scent throughout your garden. Be sure to plant it where you can bend over and take a whiff on those occasional days with no breeze. It’s an easy plant to grow and care for.
Native to Dry Areas
No wonder chocolate flower is easy to grow in New Mexico; it is native to dry plains and hills of New Mexico, Arizona, Colorado, Texas and Kansas. It grows best in elevations of 4,000 to 7,000 feet, so Berlanderia thrives in high deserts and intermountain areas like mine.
Because it’s native, and probably because it looks and smells so great, chocolate flower attracts butterflies, bees and birds. And deer leave it alone! Need more reasons to grow chocolate flower? It reseeds naturally, but not aggressively, so one plant can turn into a few or more, depending on lots of conditions and where you plant the first one. Another great feature of this native is that it will reseed more naturally if planted near rocks or gravel mulch. The rocks “trap” the seeds when they blow in the wind.
Caring for Chocolate Flower
You can plant chocolate flower in nearly any type of soil, but it probably will do best if the soil drains well. Be sure to place it where it will receive plenty of sun – up to all day – and where its mature height (about a foot to 15 inches tall, and up to two feet wide) will work without overcrowding. Give it a little more water the first year, and then chocolate flower should grow and bloom with mostly rain only. Each spring, trim off dead flower stalks and some of the foliage if necessary to keep the plant base about three inches high.
Chocolate flower is a perennial in zones 4 through 11, although ask for the variety best for your area. For example, High Country Gardens has introduced a new Mora County mix of B. lyrata that is particularly cold hardy (Mora County is a mountain and high plain area just northeast of Santa Fe). Deadheading, or removing spent blooms, keeps Berlanderia blooming.
Enjoy Growing Chocolate Flower
Chocolate flower is in the daisy family, a relative of the sunflower and others, so it makes a nice cutting flower as part of an arrangement. You can bring that soft chocolate scent inside! I love the color of the flower buds – they look like a sage green paper flower. Its growth habit is bright and colorful but just wild enough to fit in a natural looking, xeric landscape. Leave some of the drying flower heads on your chocolate flower at the end of the season if you want it to reseed in your garden. Then watch in spring. If conditions are right, you might see a few new crowns of chocolate flower with the distinctive leaf pattern.
It’s a good thing chocolate flower can spread, because you can’t move it. The plant has a tap root (which helps its drought tolerance) that doesn’t survive division or transplanting. Otherwise, chocolate flower is a perfect, sunny perennial for a xeric garden.
It’s spring and time to think about growing food and flowers this summer. Save money when you start some seeds inside. You can find plenty of tips online for light, soil and water requirements, but I wanted to mention a few other hard-earned “secrets” from my experience and talking to others.
In general, start seeds about six weeks before your planting time for the variety. And be sure to pot up (move the smaller seedling to a larger pot) once while seedlings are inside. Here are 5 other tips:
1. Before starting vegetable or herb seeds, be sure they transplant well.
If they do better with direct sowing (placing the seed right in the ground), wait not just past your last freeze but until air (and therefore, soil) temperatures have warmed. Cucumbers are a great example. I have planted them too soon and then had to plant again when the ground warmed because the first ones just didn’t take. Many annual flower seeds and some herbs do fine with direct sowing, which is easier than starting small plants inside.
2. Not all vegetable seeds or seedlings go into the ground at the same time.
Lettuces, cilantro and carrots do better in spring or early fall than in summer heat. Tomatoes need moderate heat. Planting and harvest times vary for edibles. This also goes with my next tip:
3. Look for information specific to your region.
Seed packets can help, but in New Mexico and other Southwest states, dates for planting vary widely. This goes for last or first frost dates and for peak heat. Low desert areas, in particular, have growing seasons markedly different from the rest of the country. Check with local nurseries, extension offices or master gardeners for help knowing when to plant.
4. Thin seedlings.
This is the hardest lesson. But you should thin the seeds that sprout in your indoor start pots and those directly sown before they get too big and share roots. In the starter pot, it is best to take a small narrow pair of scissor or garden clippers and cut the spare seedlings off at the soil level. Pulling it up could damage all the seedlings in your pot. Thinning in the ground is a matter of preference for how your plants will look. But remember, crowded seedlings are not as healthy as single ones with plenty of room for their roots, and vegetable plants should not touch one another if possible. The leaves need sun and air flow.
5. Be sure to harden off seedlings.
This requires patience and some time. Your plants need to get used to their new home, just like flatlanders need to acclimate to high altitudes. Get your seed starts used to a breeze and the sun before placing them in the ground. Read more here about how to harden off your seed starts.
Finally, start just enough for a spare or two in case a few seeds fail to take or the seedlings get off to a bad start. But don’t plant 10 tomato seeds indoors if you plan to grow only one or two plants, unless you have friends and family who would love to take your other healthy plants off your hands.
It sounds too good to be true: an ornamental grass that loves heat and looks beautiful all year gently swaying in the wind. But threadgrass (Nasella tennuissima) fits the bill — and is waterwise. This pretty low-water plant also is called silky thread grass or Mexican feather grass.
Texture and movement can add to a garden’s design nearly as much as shape and color. Threadgrass has a delicate, windswept form that serves as an attractive backdrop to low-growing flowering plants like sedums or verbena. In summer, the grass is a nice green with feathery ends. In winter, the airy flower heads take on a golden, wheat-like appearance. Threadgrass is deer resistant, has no known diseases or pests, and is a native plant that grows in zones 5 through 10.
Plant threadgrass in spring, summer or fall. Because it likes heat, you might be able to fill in a summer bare spot with threadgrass after weather is too hot for most garden plants. If you want a swaying meadow effect, you’ll need to plant a few, and then wait for them to reseed. If you want immediate effect, plant several. Just keep in mind the plant grows to about 12 inches wide.
Your threadgrass plants should reach about 18 to 24 inches high when fully grown, sometimes higher when blooming. Plant it in full sun and in most any kind of soil. When you first plant or transplant your threadgrass, give it a little extra water, especially in high heat.
Caring for Threadgrass
Once threadgrass is established, it should need nothing but rain water to grow and set seed. The plant is a short-lived perennial and should come back several years in a row, assuming typical low temperatures for the lower zones. It also reseeds (see below), creating new plants nearby. You can leave these to eventually replace the established ones, or dig them up and transplant them to another spot in your garden. They are easy to recognize.
Each spring, as you begin pruning other plants in your garden, gently comb the grass blades with a fine rake and trim them for shape.
Caution for Some Gardeners
The fact that threadgrass replaces itself by sprouting tiny plants from seed is a bonus to me. We get just enough seedlings to move around our garden, without them being a problem. But in some areas, threadgrass can be invasive, reseeding in places where it interferes with other plants. In fact, the plant is prohibited in California because it is so invasive there and can crowd out grasses native to coastal areas. It also can crowd out pasture grasses. We have had no problems with that, however, and have only seen the plants pop up near mature ones.
Roses are red for Valentine’s Day, but there are other plants, including houseplants, bulbs and a few xeric plants that make great Valentine’s Day gifts with their deep red blooms.
Here are my favorites:
This xeric salvia (Salvia gregii) is a garden stunner. Add one to your rock garden for all-season color in most regions of the Southwest (zones 6 through 10). Hot lips sage is a perfect plant for lovers with bright red and white blooms.
Red or Iceland poppies are perfect flowers for pressing and can last a bit as a cut flower. Papaver rhoeas (Red or Shirley Poppy) is a gorgeous complement to other flowers in the garden or planted in a bunch for a bright red meadow.
Geraniums come with deep maroon red, fire engine red or pink flowers. Plant a red geranium and a white geranium in a container for your Valentine. These plants can stay outside in spring or summer in most areas of the Southwest will continue to bloom inside in winter if left in a sunny window. I like to cut the bloom stalk near where the flowers begin and float it in a clear glass container filled with water.
If the symmetrical rosettes of leaves topped by pretty flowers are not enough (and they should be) to brighten any home or heart, the plant names might do the trick. There are thousands of varieties of African violets hybridized by pros and amateurs with fun registered names. Hybridizers name the violets after loved ones, hobbies and the plant characteristics. There are plenty of varieties with pink and reddish flowers (not just purple ones) .
Many varieties of the winter-blooming bulb come in solid red or white with red or coral streaks. Although most are raised to bloom around the holidays, they can bloom later if dormant and dark for a while, or have a second bloom. I have one that bloomed like crazy in December but has another bud coming up that likely will open just after Valentine’s Day.
Although cut flowers are nice, a plant that can grow on in your garden or home makes a perfect gift for your Valentine. Tulips open outdoors in early spring, and even Claret cup cacti have gorgeous red blooms. My all-time favorite cutting flower is the gladiola and a nice guilty pleasure in an otherwise low-water garden (and protected from munching deer). Or try giving your loved one an anthurium, the tropical plant with a red heart-shaped flower!
Not sure what to give a loved one, friend or co-worker as a holiday gift? You can’t beat succulents. Here are five reasons why:
1. Easy care, even for brown thumbs.
Although succulents can die, they are easier to care for than most plants. You can kill them only with kindness (too much water). And even leaves of heat-loving succulents can burn in direct sun. But they make great gifts for people who want a little green but have less than green thumbs. Keep it simple with common succulents like Echevaria or Sempervivum. Both plants come in pretty rosette shapes.
2. Succulents make people smile.
Partly because they’re easy, and maybe because of their fleshy, healthy-looking leaves or pads, these plants bring a touch of natural, living matter to the dullest setting. You can find popular ways of displaying succulents as décor. And if the recipient likes to live on the edge, a nice spiny cactus is a fun gift that could be the gateway to growing more houseplants.
3. Succulents grow in lots of container types.
A few weeks ago, I posted about growing cacti in containers. Succulents are so easy to plant in natural, pretty or quirky containers. Small ones can grow in tiny holes of rocks or driftwood. Air plants are even easier to grow in unique containers, since they require no soil.
4. Adding a personal touch is easy.
So, maybe the succulent you choose for a gift isn’t so unique, but you plant it in a coffee cup with a message, or a souvenir that has sentimental value. You can use your sense of humor or a little romance when choosing how to present a small succulent – or several. Or select one based on the name (maybe String of Pearls?) You also can make your gift more personal with a small set of instructions on how to care for the plant. You can look for information online or write up how you take care of succulents.
5. They’re popular and available.
The trend in succulent plantings, arrangements and decoration on all sorts of materials might not last forever. But while it does, it is easy to find a great selection of succulents for gift-giving.
Here are some favorite small succulents:
Echevaria, several varieties
Sempervivum (such as hens and chicks)
Sedum morganianum (Burro’s tail)
Euphorbia milii (Crown of Thorns) and it is thorny!
Crassula ovata (Jade plant)
Mamillaria crinita (Pincushion cactus)
Haworthia fasciata (Zebra plant)
Zwartkop (Aenonium arboretum)
Also, Tillandsias (airplants) come in lots of types and colors.
Succulents, and especially cactus plants, usually prefer heat and drought. That’s one reason they make such perfect plants for desert gardens. But in the high deserts or mountains of New Mexico and other Southwestern states, many cacti only can live outdoors in the summer. Enter containers…
Why Plant Cacti in Containers?
The best reason for planting cacti in containers is the flexibility it offers. You can move the plant throughout the year (carefully) to bring it outdoors when summer nights warm and indoors as frost approaches. But you also can move your cacti around to control temperature or sun exposure. Even succulents can burn from intense sun, so it is good to keep an eye on the plants and rotate or move them depending on sun, including sun from a south- or west-facing windows.
Another reason to plant cacti in containers is to isolate watering. When planted outside, especially near drip or other watering systems, cacti can get too much water. With containers, you can control cactus watering based on season and when the plant goes dormant. If you love the look of a cactus in your desert landscape, nothing says it has to be in the ground! If the water or temperature conditions are not ideal, place your cactus outside in a colorful container. Just remember – the outdoor container should have good drainage and can cool off more at night, so don’t leave a container cactus outdoors in winter unless it is hardy to at least 10 degrees cooler than your lowest low.
Finally, most cacti are slow growers, so you don’t’ have to repot them often. Other cacti spread out of control in the garden. You’ve probably seen a xeric yard in your neighborhood with prickly pear growing like a sprawling hedge, maybe onto the sidewalk. It is easier to control cacti when in the confines of a container.
Container Cactus Mix
Planting and caring for cacti in containers is easy, but the soil mix is crucial to success. If you plant a cactus in standard container potting mix, which is designed to help retain water, your cactus roots will get soggy and rot. You can buy special cactus mixes or make your own. Ask friends or local experts for ideas. Examples include adding 1 part coarse sand and 5 parts perlite (for airflow and drainage) to 4 parts of potting mix. Vermiculite also improves aeration but holds too much water. You also can add a little bit of rock dust or pumice to your mix.
Handle your cactus carefully while transplanting. You can use an old sock or towel to wrap around the plant near the base and lift it out of the pot. Or turn the pot with the cactus on its side, resting the plant on an old pillow (that you won’t use again) to cushion the plant while you pull the container off the root ball.
Old long-handled barbecue tongs are great tools for holding a cactus while you place it in its new container; or use regular tongs for smaller plants. The eraser side of a pencil works great for gently pressing soil down around smaller cacti.
Some Favorite Container Cacti
Some of these cacti are spinier than others, so you might want to be careful where you place them. Many will flower, especially in spring or early summer. And some can tolerate pretty cold temperatures, but still would be fun winter houseplants.
Barrel cactus (Echinocactus grusonii). The golden barrel and other barrel cacti are such great landscape plants, giving a pretty round shape to landscape designs. I especially love them on hills. But they’re only hardy to 15 to 17 degrees, so we keep ours in a container.
Pencil cholla (Cylindropuntia leptocaulis). Pencil cholla are pretty scary looking, with spines up to one inch long sticking out from tall, thin branches. They are hardy to -20 degrees and love heat, but spread easily in the yard.
Bishops cap (Astrophytum myriostigma). This is an attractive and slow-growing cactus perfect for a container, especially since it only can handle cold down to 20 degrees. I love the sort of grainy white and green look of the plant. See the second photo above. That is a bishops cap in the middle.
Hedgehog cacti (Echinocereus). It’s native to the U.S. and Engelmanns hedgehog is most common throughout the Southwest. It’s spiny, but should produce bright pink flowers more than two inches across. The plant only reaches about 10 inches in height.
Fence post (Pachycereus maginatus). This is a columnar, almost regal cactus. The columns have ridges with small spines and when planted in a row, they form an excellent wall. Columnar cacti are great choices for planting in containers of homes with high ceilings or to simply provide height behind a grouping of houseplants. They just need plenty of filtered sun.
Ocotillo (Fouquieria splendens). It’s hard to imagine this sprawling cactus in a container, but it can be done. It will need summer heat and can survive temperatures down to 20 below freezing. So, the garden can work, but you can control ocotillo growth in a container and enjoy it as a rising backdrop to other cacti or succulents.
Old man cactus (Cephalocereus senilis). This is by far one of my favorite cacti. But it needs to stay in temperatures above 46 degrees, despite its shaggy layer of “hair.” This is another slow grower, and often a conversation starter in a home!
Spineless prickly pear (Opuntia canacapa). For the look of a gorgeous green and juicy cactus pad and no spines, go with this pretty plant. It still will grow new pads, but you can cut them off or plant them elsewhere. Both regular and hardy prickly pears can survive temperatures down to zero.
The leaves are falling, but you don’t have to sink into winter doldrums. You can keep up your green thumb and all the joy you get from growing with indoor plants. All that greenery inside your house is much more cheerful than the brown landscape and bare trees outside. So fill your home with green and flowers.
Here are a few ideas on how to extend the season and ease into winter slowly.
Adjust houseplant conditions
Even houseplants that live indoors all year might need some winter preparation. This includes cutting back on watering and fertilizing and cleaning leaves to allow as much light as possible to reach the plant. Because winter days are shorter, and the sun in the northern hemisphere is lower, you might have to move plants to different windows or supplement their light with grow lights. And be sure not to overwater houseplants in winter. Most need a break to rest, and only need water when the soil dries out.
Move container plants inside
We move inside any plant we love and think can make it at least a few months inside. It helps if it is not too heavy to move. This includes many succulents that can’t take low temperatures, geraniums, and plants that tolerate shade. We had a gorgeous coleus container we brought inside one year. It got leggy, but we were able to enjoy it for a few months more than if we had discarded it.
Harvest or grow edibles
Pick green tomatoes if still viable on the vine and let them ripen indoors, fry them up or make a tomato sauce starter. Making pesto is fun, but you also can cut basil branches and place in a jar of water for extended life. If canning is your thing, it feels good to prep for winter by preserving fruits and vegetables. When you miss your summer garden, visit the dark cool area where the jars of your preserved crops are stored. You can grow sprouts in glass jars to “summer up” sandwiches and salads.
Take cuttings of favorite plants
That coleus that got too big and lanky? We could have rooted new coleus plants from cuttings instead of bringing the mature plant inside. There’s a fun indoor project! In fact, try taking cuttings of favorite plants and starting them indoors. Not all plants are easy to propagate, but with some practice, you can start your own plants for the next spring.
Buy a new houseplant
African violets can bloom almost continuously if they receive enough sun and consistent, light moisture and repotting as needed. There are thousands of varieties with different bloom colors and styles and variegated leaves. Many succulents bloom in winter (such as Christmas cactus) or in spring, when you’re really itching to get outside and grow. Both succulents and African violets also are easy to grow from leaf cuttings, though the technique is very different for each.
