Botanical Description
Silphium integrifolium, commonly known as whole-leaf rosinweed or entire-leaved rosinweed, is a tall perennial herb in the Asteraceae family, native to the central United States, ranging from Wisconsin and Michigan south to Texas and Louisiana, with greatest abundance in the tallgrass prairies of the Midwest. It grows 60-180 cm tall from a stout taproot and woody rootstock, with erect, stiff, somewhat hairy or scabrous stems that exude a resinous, aromatic sap when cut. The leaves are opposite, sessile or nearly so, broadly lanceolate to ovate, 5-15 cm long, with entire or very shallowly toothed margins and a rough sandpapery texture on both surfaces. The inflorescence is a terminal open corymb of several yellow flower heads, each 4-7 cm across, with 15-30 bright yellow ray florets surrounding a yellow disc. The phyllaries are broadly ovate and overlapping. It inhabits dry to mesic prairies, open woodlands, and grassy roadsides.
