Wyethia amplexicaulis (Nutt.) Nutt.
USDA Symbol: WYAM
USDA Native Status: Native to U.S.
Large, round, shiny leaves subtend a stout but lax stem, 1-3 ft. tall. Stem leaves are more lance-shaped, resembling the ears of mule. A large, yellow, sunflower-like flower head is often surrounded by smaller yellow flowers. Plant seems varnished with resin, the stout leafy stems growing from clumps of lanceolate leaves, ending in several large deep yellow flower heads on long stalks, the central head largest.
All species have leaves on the stem, distinguishing them from Balsamorhiza, which has all leaves at the base.
