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 rebloom well without deadheading, however prompt removal of spent flowers encourages continued bloom and improves general appearance.
Noteworthy Characteristics
Echinacea is a genus of seven species all endemic to eastern and central North America. Coneflowers bloom from June to August with some sporadic later bloom. Attractive to butterflies and other insect pollinators. 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.
SUNDOWN is a new hybrid coneflower in the Big Sky Series from Richard Saul of Itsaul Nurseries in Atlanta, Georgia. It is reportedly the result of 2002 cross-pollination of two unnamed Echinacea hybrid selections. This is an upright and columnar plant with free branching that typically grows in a clump to 32-36” tall and to 18" wide on sturdy stems that do not need staking. It is noted for its large, slightly-fragrant coneflowers (to 4” diameter) featuring overlapping, slightly reflexed, russet-orange rays with dark brown center cones. Flowers bloom from late spring to late summer, sometimes with additional sporadic bloom until frost. Strigose, coarsely-toothed, dark green leaves (to 4-5” long) are lanceolate. U.S. Plant Patent PP17,659 issued April 24, 2007 under the cultivar name of 'Evan Saul'.
Problems
Susceptible to aster yellows disease and eriophyid mites. Deer tend to avoid this plant.
Uses
Border fronts, rock gardens or part shade areas of open woodland gardens. Best in groups or massed. Attractive specimen/accent.
