Ecology & Habitat

Description

Linearleaf Fleabane has unbranched stems that are 5-30 cm tall and which arise from a stout taproot and branched rootcrown. The mostly basal leaves are linear and 1-9 cm long. The bases of the stems and leaves are enlarged and straw-colored or purplish, and the herbage is covered with fine gray hairs. The flower heads are usually solitary at the ends of the stems. The involucral bracts are 4-7 mm long and are covered with long, appressed hairs and occasionally also with glands. The 15-45 yellow rays are 4-11 mm long and the yellow disk flowers are 3-5 mm long. There are 10-20 pappus bristles at the top of each achene.
