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:
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.
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.
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.
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.
