General Culture:
Easily grown in average, dry to medium moisture, well-drained soils in full sun to part shade. Best in full sun. This is 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.
Noteworthy Characteristics:
‘Prairie Giant’ is a purple coneflower that, as the cultivar name suggests, is distinguished by its giant features: flowers (6-9” diameter), basal leaves (to 24” long) and stiff stems (to 40” tall). Each flower features narrow light pink rays with a dark center cone. Stems are clad with irregularly serrate, rough, tapering, narrow-ovate, dark green leaves. Flowers bloom from June to early September, sometimes with sporadic later bloom. Dead flower stems will remain erect well into the winter, and if flower heads are not removed, the blackened cones are often visited by goldfinches that feed on the seeds. Echinacea comes from the Greek word “echinos” meaning hedgehog in reference to the flower’s spiny center cone.
Problems:
No serious insect or disease problems. Japanese beetle, powdery mildew and fungal leaf spots are occasional problems.
Uses:
Border fronts, cottage gardens, wildflower meadows or part shade areas of open woodland gardens.
