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.
‘Purity’ is a compact, vigorous, white-petaled coneflower that typically grows in a well-branched, upright clump to 18-24" tall on sturdy stems that do not need staking. Each daisy-like flower (to 4 1/2" diameter) features white rays (petals) with a large, pin cushion-like, orange central cone. Each mature plant reportedly produces 25+ flowers per year. Flowers bloom primarily from June to August, with some sporadic later bloom occurring into fall. Flowers appear atop sturdy stems clad with lanceolate, dark green leaves (4-8” long). Although the parents of 'Purity' are unknown, this flower reportedly originated as a third generation seedling from a planned breeding program using Echinacea purpurea 'Fragrant Angel' for the original cross. In comparison to the similarly-sized Echinacea 'White Swan', 'Purity' produces larger flowers with ray petals more horizontal and larger center cones that are orange rather than yellow. U.S. Plant Patent PP19,441 was issued on November 11, 2008.
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).
