Culture

Easily grown in average, dry to medium, well-drained soil in full sun to part shade. Best in full sun. An adaptable plant that is tolerant of drought, heat, humidity and poor soil. Divide clumps when they become overcrowded (about every 4 years). Plants usually rebloom without deadheading, however prompt removal of spent flowers improves general appearance. Freely self-seeds if at least some of the seed heads are left in place.

Noteworthy Characteristics

Echinacea purpurea, commonly called purple coneflower, is a coarse, rough-hairy, herbaceous perennial that is native to moist prairies, meadows and open woods of the central to southeastern United States (Ohio to Michigan to Iowa south to Louisiana and Georgia). It typically grows to 2-4' tall. Showy daisy-like purple coneflowers (to 5" diameter) bloom throughout summer atop stiff stems clad with coarse, ovate to broad-lanceolate, dark green leaves. Good fresh cut or dried flower. The dead flower stems will remain erect well into the winter, and if flower heads are not removed, the blackened cones may be visited by goldfinches or other birds that feed on the seeds.

Genus name of Echinacea comes from the Greek word echinos meaning hedgehog or sea-urchin in reference to the spiny center cone found on most flowers in the genus.

Specific epithet means purple.

‘Kim’s Knee High’ is a compact or dwarf version of the familiar species plant. It is noted for its short habit and long summer bloom. It typically begins blooming when its rigid stems reach 15” tall (knee high). If not cut back, plants may eventually reach 24” in height by the end of the summer. This is a daisy-like coneflower that features drooping, clear rose-pink to purple-pink rays and large, pin cushion-like, coppery-orange to dark bronze central cones. Coarsely-toothed, dark green leaves (to 6” long). ‘Kim’s Knee High’ is a selection of Kim Hawks of Niche Gardens, Chapel Hill, North Carolina. U.S. Plant Patent PP12,242 issued December 4, 2001.

Problems

Japanese beetle and leaf spot are occasional problems. Susceptible to aster yellows disease.

Uses

Excellent, long-blooming flower for massing in the border, meadow, native plant garden, naturalized area, wildflower garden or part shade area of woodland garden. Often massed with black-eyed Susans (rudbeckias).
