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.
‘Leilani’ originated from a planned breeding program with parents Echinacea paradoxa x Echinacea purpurea ‘Ruby Giant.’ Its regal upright plant habit has gorgeous golden yellow flowers with greenish bronze cones that require no staking. Cultivar name means “royal child of heaven.” US PP23,526 awarded on September 21, 2011 to Terra Nova Nurseries, Inc.
