Drought-tolerant Flowers for Cutting

It’s easy to have color in a low-water garden, but many xeric flowers and shrubs have stems too short or otherwise look better in your yard than in a vase. We’re trying to turn an area of our lawn into a small wildflower meadow, and I’ve been considering growing some flowers for cutting, maybe even to sell at Farmers’ Markets. But I don’t want to pour too much water to flowers, especially annuals.

The folks at ProFlowers made it easier for me to find drought-tolerant flowers that also work well for cutting, with their guide on the 151 most common flower types in the U.S. I’m featuring five favorites from the list that use little water and can glam up a floral arrangement:

purple coneflower
Coneflowers make striking cut flowers and attract pollinators to your garden.

Coneflower (Echinacea). This is one of our favorite flowers, and we’d have one in our garden right now if a gopher had not destroyed the transplants we purchased at a local nursery. These are versatile flowers, tolerating both heat and drought, and growing in zones 3 through 9. They’re also gorgeous; coneflowers are in the daisy family, and I love how the rounded stamen, or center, rises above the petals. And it comes in many colors, including the traditional purple, along with yellow, white, raspberry and even in a mix with oranges and yellow that remind me of zinnias. Echinacea also is a popular herb, and Native Americans have long used the plant’s extract to treat wounds and infections.

Hyssop. This is another herb that uses little water and makes great cuttings. It’s called the “holy herb” for its purging or cleansing properties and the oil has aromatherapy uses. A member of the mint family, hyssop loves heat, but grows in zones 3 through 10. It’s deer resistant and drought tolerant. Pollinators love hyssop, so be sure to leave a few blooms on the plant. Hyssop is a perennial, and is evergreen or semi-evergreen in most zones. Most varieties produce mid-summer and late summer blooms in purple, blue, pink or white.

Marigold. Although these members of the Asteracea family don’t have the long stems of many cut flowers, they’re an easy, dependable and attractive annual. Most varieties come in yellow and orange. Technically not a drought-tolerant plant, marigold still thrives in well-drained soil in full sun from zones 2 through 10. To save water, I add marigolds to tomato plants or other areas of my vegetable garden. It’s said that their aroma can help deter insects. Pinching off the first few flowers before opening can help the plant produce more flowers for cutting.

Marigold blooms have such rich color and require only deadheading, or pinching spent blooms, to keep the blossoms coming.

Nasturtium. This tough flower does well in heat and poor, dry soil, and it’s edible. I love to see nasturtiums in containers, where the flowers drape over the sides. They’re easy to grow from seed, so that makes them affordable too! And the large seeds are easy to handle and space, so this is a great flower to have children help plant and then harvest. Although listed in zones 9 through 11, we’ve grown the flowers in zone 6B after summer warms up.

We went a little wild with nasturtium seeds in this antique washer. But I love the results!

Sea lavender (Limonium). I’ve never grown this pretty blue flower, although I love lavender. Maybe that’s because it prefers sandy soil that drains quickly and is a favorite of seaside areas. It’s not from the lavender family, but like lavender, Limonium does well in drier soils and drought conditions. The plant attracts birds and butterflies, and is easy to care for. Check with local nurseries or master gardeners to find the best variety for your zone, especially if you want to keep the plant as a perennial.

Sea lavender flowers are especially good at retaining color after cutting.

I’d like to add a few other flowers from the ProFlowers guide that might have had one or both qualities (drought tolerant and good for cutting). We’ve grown some in our zone 6B rock garden with success. Among those are coreopsis and cosmos for cutting, and four o-clocks (Mirabilis) and periwinkle for low-water garden color.

How To Identify Monarch Butterflies

I’m as excited as anyone about supporting Monarch butterfly conservation efforts. We plan to buy several swamp milkweed plants to add to the existing trees, shrubs and flowering plants around our property.

I got to see the Monarchs many years ago while on a visit to Pacific Grove, Calif. I’m not sure, however, that I’ve ever spotted a Monarch in New Mexico, and a map I checked had a giant question mark for much of New Mexico and Arizona, even though our states border Mexico. Although singularly striking, Monarchs look similar to a few other butterflies. What’s more, the critical aspect of saving them requires providing habitats for the butterflies’ larvae. Enter milkweed.

Monarch life cycle

Monarch butterflies lay their eggs on milkweed plants, which also attract other pollinators. The Monarchs find milkweed even when it has finished flowering for the season. The eggs are tiny (about the size of the head of a pin), but as they take on adult form, the larvae, or caterpillars, emerge and grow rapidly.

Like many gardeners, I freak out a little when I see a big caterpillar on a plant. I can’t abide tomato hornworms and the damage they inflict, and we also have had branches of several small trees stripped by the io moth caterpillar. This bad boy stings and releases a poisonous substance that can irritate the skin or cause severe reactions in some people. Last summer, we found a similar greenish-yellow caterpillar on fennel plants, or what was left of them. I think I’ve identified them now with some research.

The io caterpillar is similar in color, but has a fuzzy, fluorescent look. And it stings!

So, I wanted to be sure that I can easily recognize the Monarch caterpillar before trying to attract them to my yard. In fact, all gardeners who want to help the Monarchs should be able to recognize the insect in all forms. I would hate to hand-pick a Monarch caterpillar and end its life cycle! Strangely, finding quality resources to help me identify the caterpillars, and especially to share photos, did not come easy. I finally tracked down some information.

Monarch or Queen?

Although I don’t want to hurt the chances of any butterfly, I was relieved to discover that the caterpillars on the fennel were most likely Queen butterflies, not Monarchs. Queen butterfly caterpillars also feed on milkweed, and can share plants with Monarchs. The butterflies look really similar, but have a few distinctive differences.

Queen, Monarch and Viceroy butterflies have similar colors and patterns. Monarchs are a deeper orange, and the hue changes slightly throughout the wings. The best way to tell the adults apart is the location of white spots on the wings. The Queen butterfly has dots that extend into the orange areas of the wings. But Monarchs have a distinctive stained glass appearance and no dots outside the black edges of the wings. Viceroys are smaller than Monarchs and have triangular white dots under their wings.

You can distinguish the Monarch caterpillar from other caterpillars by the antennae. The Queen butterfly has three sets of antennae and filaments, and the Monarch has only two – one antenna pair on the front end and a filament pair on the back end. The Queen caterpillar spots an extra set about one-third of the way down from the front. Viceroy caterpillars do not look like Monarch larvae; the Viceroy caterpillar has a brown, rough appearance.

The Monarch young larva is nearly clear until it begins to eat milkweed and grow. The larval portion of the life cycle lasts about 10 to 16 days. They can become plump just before pupating, having eaten plenty of milkweed. The caterpillars move away from milkweed as they prepare to evolve to pupae.

Queen butterflies are pretty as well. This one enjoys a butterfly weed flower in Northeastern New Mexico.

Got Bees? Join the Million Pollinator Garden Challenge

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!

We were stuck with ivy around all of our walls at our last home. We pulled out any that was rooted on our side of the fence. It’s not xeric and it is invasive, but butterflies flocked to the blooms.

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.

Maximilian sunflower (Helianthus maximiliani) is a native, low-water prairie flower that bees love. I love its late-season blooms.

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.

If your garden already meets the criteria, I encourage you to go to the challenge’s website and add your garden to the map.

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.
yarrow and gallardia
Moonshine yarrow (Achillea millefolium) is a perfect pollinator. It blooms all season and has a flat surface for easy landing! Bees also love the annual blanket flower (Gallardia)
  • 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.
