Additional comments: Echinacea is a nice old fashioned plant for mixed, mesic flower gardens that attracts butterflies and bees; seldom seen in Phoenix gardens. It performs oh so much better in the higher elevation cities of Arizona such as Prescott, Flagstaff and Payss a summer annual. There are nine known species of echinacea, all of which are native to the United States and southern Canada. The aboveground parts of the plant and roots of echinacea are used fresh or dried to make teas, squeezed (expressed) juice, extracts, or preparations for external use. Studies to date have not proven that echinacea shortens the course of colds or flu. Echinos is Greek for spiny and pointed like a sea urchin or hedgehog.
