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.
'Milk Shake' (or 'Milkshake') is an upright, hybrid selection of coneflower that features strong stems, double white blooms, and a well-branched habit. Mature clumps will reach up to 3' tall and spread to fill a similar area. The fully double flowers feature drooping, creamy white, rays surrounding a globular, pompom-like center cone of pale yellow-green to white elongated disk florets. The double flowers of this cultivar are not as attractive to pollinators as single flowers. Commonly sold in nurseries and garden centers under the name CONE-FECTIONS. Plant patent number PP20594 applies to this cultivar.
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.
