Echinacea purpurea - Purple Coneflower (Asteraceae)
--------------------------------------------------------------------------------------------
Echinacea purpurea is a perennial for sunny to
peduncles become fruiting stalks; in addition, the
partially shady sites, with a distinctive array of
receptacle is covered with prickly coarse scales
summer-blooming pink-lavender or white-cream
-best floral performance occurs by putting this
flowers. The sometimes pendulous petals sit atop
perennial in sites with morning sun followed by
stiff, vertical peduncles that arise from a clump of
afternoon shade, so that the petal colors will not
bleach out in the intense afternoon heat and sunlight
FEATURES
-each of the stiff flowering stalks has several flowers
blooming over a month long period in July and early
Aug., with occasional rebloom during late summer
and early autumn, especially if deadheaded
-seeds, as a unit, form a prominent central cone that
turns gray in autumn, with seeds slowly shattering
-performs best in evenly moist, well-drained soils of

average fertility in partial sun, but is tolerant of full
deadheaded or subjected to autumn cleanup),
sun, heat, and drought (as long as a moderate amount
therefore, the fruiting heads are not especially
of petal bleaching and leaf scorching is expected)
-propagated by clump division, root cuttings (not
rooted stem cuttings, but cuttings from the peripheral
Function
-Daisy Family, with minor foliage disease (leaf spot)
-mass or group plantings, borders, entranceways, rear
or pest (Japanese beetle) problems; however, leaf
of the perennial bed, and naturalized prairie or
scorch is the most common problem and often occurs
woodland edge sites; also good for cut flowers
-cut back dead stubble from the previous season's
growth during late autumn, late winter, or early
-heat and drought tolerant (although some leaf scorch
-medium to dark green, either originating as a clump
from the crown (basal leaves are up to 8" long) or
-will slowly self-sow when placed in a neglected area
