Did you know

  • Flannel bush produces spectacular 2–3 inch wide golden-yellow flowers that are not petals but sepals — the true petals are absent or vestigial, and the entire showy display is provided by the five waxy sepal lobes.
  • All parts of the plant are covered in star-shaped (stellate) hairs that break off and irritate skin, eyes, and mucous membranes on contact — handling the plant without gloves causes intense itching that can last hours.
  • The species was named for the explorer John C. Frémont, who collected specimens during his surveys of California in the 1840s — Frémont also gave his name to Frémont cottonwood and Frémont's pincushion plant.
  • Flannel bush requires absolutely no summer irrigation once established — in fact, summer water is the most common cause of its death in cultivation, reflecting its dry chaparral origins.
  • In California chaparral, flannel bush is a fire-follower: seeds lie dormant in the soil for years, requiring the heat of a fire to crack the hard seed coat, and populations explode spectacularly in the first spring after a chaparral fire.
