Coneflowers, also known as Echinacea, are tough little native flowers that draw butterflies, bees, and birds to the garden! Here’s how to grow this American native—and important tips on plant care, from deadheading to cutting back in July.
Bright upright plants, coneflowers are a North American perennial in the Daisy family (Asteraceae). Specifically, the plant is native to the eastern United States, from Iowa and Ohio south to Louisiana and Georgia. They grow 2 to 4 feet in height with dark green foliage. They are fast growers and self-sow their seed profusely. These midsummer bloomers can flower from midsummer through fall frost!
Their genus name Echinacea comes from the Latin name for hedgehog, echinus, referring to the often prickly lower stem of the plant. Coneflowers have raised cone-like centers (hence, the name) which contain seeds that attract butterflies. Leave the seed heads after bloom and you’ll also attract songbirds!
Trouble-free, coneflowers are drought-tolerant, once established. They can take the heat! As native plants with prickly stems, they are more deer-resistant than most flowering plants.
The most common species available to gardeners is Echinacea purpurea, the purple coneflower. If purple doesn’t pair well with your garden’s color palette, don’t fret: coneflowers can be found in a range of bright or subdued colors.
Coneflowers are at home in a traditional garden or a wildflower meadow; they are striking in masses, especially as a mix of various colors.
CHOOSING AND PREPARING A PLANTING SITE
- Coneflowers prefer well-drained soil and full sun for best bloom. Choose a location where the coneflowers won’t get shaded out nor shade out others.
- They may reach between 2 and 4 feet in height, depending on variety.
- Coneflowers are very tolerant of poor soil conditions, but they perform best in soil that’s rich so mix in organic matter if needed.
- Coneflowers are drought tolerant.
Loosen the soil in your garden using a garden fork or tiller to 12 to 15 inches deep, then mix in a 2- to 4-inch layer of compost. (Learn more about preparing soil for planting.)
WHEN TO PLANT CONEFLOWERS
- More commonly, coneflowers are bought as small plants with blooms already on the way. These should be planted in spring or early summer.
- Coneflowers can be started from seed in spring indoors (about a month before the last spring frost date) or outdoors (when the soil temperature has reached at least 65°F/18°C).
- Note: Coneflowers started from seed may take 2 to 3 years before producing blooms.
- Better yet, don’t cut back coneflower plants and they’ll self-seed successfully!
- If dividing or transplanting coneflowers, do so in the spring or fall.
HOW TO PLANT CONEFLOWERS
- Plant coneflowers about 1 to 3 feet apart, depending on the mature size of the variety.
- If you are moving a potted plant into the ground, dig a hole about twice the pot’s diameter and carefully place the plant in the soil. Bury the plant to the top of the root ball, but make sure the root ball is level with the soil surface. Water it thoroughly.
