Grayhead Prairie Coneflower
Flowering heads are strongly cone-shaped,
with from 5 to 10 yellow, drooping ray-flowers radiating outwardly
from the base of the cone. Disc flowers form a narrow to broad,
brownish band, around the cone, immediately above the ray flowers.
The leaves are deeply lobed, to the point of being pinnately
compound, and occur individually on the stem. The leaflets (or
lobes) are narrow and elongate. Leaves near the base of the stem
may have from 7 to 9 leaflets, and those near the top, fewer
(3 to 5). Simple leaves, having one blade, may occur below the
flowering head. Leaflet edges have from one to several conspicuous
teeth, but teeth are absent from some. Stems may be branched,
with each branch bearing a flowering head at the terminal end.
Large leaves are 18 cm or more in length. Stems and leaves are
covered with fine hairs. Found on native and planted prairies
during June and July. Native to N. A.
