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:
‘Avalanche’ is an upright, compact cultivar featuring coneflowers with white rays and yellow green center cones. It is a patented plant that was originated from a cross pollination in Bovenkarspel, The Netherlands in July 2003. It typically grows in an upright clump to only 15-18” tall on rigid stems clad with rough, irregularly serrate, tapering, narrow-ovate, dark green leaves (to 7” long). Flowers bloom from June to September, sometimes with sporadic additional bloom to frost. 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. U. S. Plant Patent PP18,597 was issued on March 11, 2008.
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.
