Plant Notes:Pinnate Leaf Coneflower is a native herbaceous perennial in the Sunflower family (Asteraceae). It is found in Bibb and Shelby counties in central Alabama. Pinnate Leaf Coneflower occurs on limestone outcrops, on cedar glades, in pastures, and on roadsides. It is a short-lived perennial with a rhizome. Stems are 1-3 feet in height, branched, reddish-purple or green in color, and pubescent with long white hairs. Leaves are basal and cauline. Basal leaves form a rosette and may not be present at flowering time. Cauline leaves are alternate. Leaves are petiolate (upper ones may be sessile), ovate to elliptic in outline, entire or toothed (upper) or 5–7 lobed (basal and lower cauline), and pubescent with long white hairs. Flowers are produced in heads. The heads are in panicles. Each head has 8-15 yellow or orange ray flowers and 150-300 purple-black disc flowers. The ray flowers may have a maroon base. The fruit is an achene. Pinnate Leaf Coneflower is listed as a S2S3 species in Alabama (typically 6 to 100 occurrences making it very vulnerable in the state) and globally as a T3 species (Vulnerable - at moderate risk of extinction). Var. pinnatiloba is confined to Virginia, North Carolina, Kentucky, Tennessee, Alabama and Florida.—A. Diamond
