Other names and notes
(Purple coneflower, Broad-leaved purple coneflower). Identified by the large flower head ( 2 1/2 to 4" wide) with reddish purple slightly drooping rays, 1/4" to 1/3" wide, and a very bristly central disk; this plant has long stalked lower leaves that are egg shaped and anywhere from 1.5 to 5 times as long as wide. Leaves are toothed and hairy. Stalks are quite erect and can reach 5 feet in height. The genus name, Echinacea, is Greek for sea urchin, referring to the prickly central disk. Purpurea is also Greek, meaning "purple". The Pale Purple Coneflower, E. pallida, has narrower very drooping rays, long and thin leaves, and stems that are usually in a cluster.

Notes: This plant was listed on Martha Crone's 1951 inventory of plants in the Garden at that time. While native to many states East and South it is not native to Minnesota but was introduced and has sometimes escaped to the wild. Ms. Crone listed it under the old scientific name "Brauneria purpurea". It is not listed on the 1986 Garden census but returns with the 2009 census. Only Echinacea angustifolia DC., the Narrow-leaved purple coneflower is native to Minnesota.
