Description

This native perennial plant is up to 3' tall and unbranched. The stout central stem is greyish or reddish green and covered with coarse white hairs. Most of the leaves occur near the base of the plant, although a few of them alternate along the lower 1/3 of the stem. They are up to 9" long and 2" across, and narrowly lanceolate, oblanceolate, or ovate. The margins are smooth, but often curl upward, while the upper and lower surfaces of the leaves are covered with fine white hairs. Leaf venation is primarily parallel, although a few fine pinnate veins may be present. A single daisy-like composite flower develops at the top of the stem. It is about 3" across, consisting of a prominent reddish brown cone of disk florets, which are surrounded by 12-20 light purple ray florets. The ray florets are long, slender, and droop downward. There is no noticeable floral scent. The blooming period occurs during early summer and lasts about 3 weeks, after which the ray florets shrivel away and the central cone turns black. The achenes are without tufts of hair. The root system consists of a stout taproot.

FRUITS: Achenes, small, 4-sided, glabrous, tipped with toothed crown, enclosing small seed.

USES: Native Americans used the leaves to treat rheumatism, mumps, and measles and the roots to treat burns and toothaches. The root was also chewed as a cold remedy and to increase saliva flow to prevent thirst. A tea made from powdered roots and leaves was drunk to treat sore gums and sore throats.

CULTIVATION: The preference is full sun and average to dry conditions. The soil can contain loam, clay, or rocky material. There is a tendency for Pale Purple Coneflower to flop over when in bloom if it is pampered by too much water or lacks adequate support from adajacent vegetation. It doesn't seem to be bothered much by disease, and withstands drought very well. Development is slow unless ample sunlight is received. This plant can fail to survive the winter if the central taproot is not covered with sufficient soil.

HABITAT: Pale Purple Coneflower occurs occasionally throughout Illinois, except in some of the Southern counties. Habitats include mesic to dry black soil prairies, openings in dry rocky woods, Oak savannas, limestone glades, abandoned fields, and open areas along railroads. It is possible that this plant occurred in gravel or dolomite prairies before these habitats were largely destroyed by development.

This plant usually precedes Echinacea purpurea (Purple Coneflower) in bloom by about 2-4 weeks. Sometimes their flowers are difficult to tell apart, but the leaves of Pale Purple Coneflower are more long and narrow, hairier, lighter green, and tend to remain near the base of the plant.
