[science.halleyhosting.com] Description, Native American food source: Bitterroot is a very attractive wildflower suited for dry, naturalized gardens. It is a low plant with numerous narrow leaves in a basal rosette (See photo at right.), and lacking a large flower stem with leaves. The thick, fleshy leaves appear before the flowers appear and whither as the flowers bloom. The large showy flowers are variable in color, from whitish, rose, to deep pink and occasionally a light peach color. The stamens are numerous, numbering 30-50. There may be just one flower on the stem, but more typically there are 2-3. After flowering, the sepals close around the ovary. On maturation of the seeds, the sepals and enclosed ovary as a unit tend to break free of the scape and are then blown across the ground, scattering seeds away from the parent. The fleshy taproot, although bitter in taste, was highly prized by native Americans as a food source. Commonly it was dug as the leaves developed, at a period when they were less bitter. They were peeled and boiled, then eaten immediately or dried for later use. The bitterroot is also the state flower of Montana. (link added by Mary Ann Machi)
