Tasselflower is a shrubby plant growing one to three feet tall. It has distinctive large triangular leaves with pointed tips and nodding, tassel-like, cream colored flower heads. Flowers are up to 2 inches long and have no petals, only disk flowers. It blooms from July through October at elevations up to 10,000 feet. Traditionally, leaves were used medicinally as an antirheumatic, a liver medicine, to treat flatulence, overeating, headaches, and influenza. The seeds are said to be poisonous by one tribe but were also made into a meal to improve cakes by the same tribe. The plant was used ceremonially and the branches used to make brooms. Source.
