Seed: Echinacea purpurea is commonly started by seed, in fact, it will typically self-sow seed in the landscape. It is best to propagate Echinacea by division or seed. They are also deer resistant, meaning that deer do not prefer to eat them. Coneflowers have a high degree of drought resistance once established, making them a great addition to a water-wise landscape. So deadheading should be delayed as seed heads are very attractive to goldfinches in the winter.Įchinacea species have strong, sturdy stems that require no staking making them popular as low maintenance perennials in the flower garden, as well as specialty cut flowers. Butterflies use Echinacea as a nectar source, and birds enjoy the seeds. Landscape UsesĮchinacea’s upright, coarse texture lends itself nicely to mass plantings in naturalized areas or the rear of perennial beds.
Once Echinacea is established in the landscape, dead foliage and stems can be removed each year in the fall, winter or early spring. In the absence of a soil test, they can be maintained with an application of 12-6-6 slow release fertilizer at a rate of 1 pound per 100 square feet in late March or early April, just before new leaves emerge.įall is the best time for planting Echinacea for more information on planting, see fact sheet HGIC 1153, Growing Perennials. Proper spacing between plants will increase air circulation between plants to keep leaves dry and help prevent the spread of diseases.Ĭoneflowers are not heavy feeders. Coneflowers will reach up to 4 feet tall and 20 to 28 inches wide depending on species and growing conditions.
They will grow well throughout South Carolina, except for the coast, due to their poor salt tolerance.Įchinacea has an upright habit and coarse texture. Coneflowers prefer evenly moist, well-drained soils however, they are drought and heat tolerant once established.
