摘要

Coneflowers (Echinacea) are members of the aster or daisy family (Asteraceae). Depending on the taxonomy system utilized, there are nine species, all of which are native to North America (McGregor, 1968). Three of these species, E. angustifolia, E. pallida, and E. purpurea, are of commercial interest for their reputed medicinal properties (Sari et al.’ 1999). The coneflowers are also popular garden and cut flower subjects. Plants can remain in bloom for long periods of time in garden settings, are quite drought tolerant once established, are adaptable to a range of soil types and pH, and are hardy from U.S.D.A. Zones 3-8. The flowers attract butterflies and honeybees, and the seeds attract birds such as goldfinches. One species, E. purpurea, the purple coneflower, is widely cultivated as an ornamental. In its myriad selected forms, it can range from 18 inches to 5 ft in height, and will produce for 2months or longer numerous flowering heads with showy ray flowers in white to pink to rose-red, andraised purple to golden center disks. Several other species are also cultivated, to a lesser degree, as ornamental plants, including E. angustifolia (blacksamson), E. pallida (pale purple coneflower), E. tennesseensis (Tennessee purple coneflower), all with light pink to dark rose red flowers, and E. paradoxa (yellow coneflower), truly the paradox of the genus with its yellow flowers. None of these latter species have been developed beyond the wild type to any degree.
