Did you know

  • The showy yellow 'petals' are technically sepals — Fremontodendron has no true petals, and the golden display is entirely provided by five large, petal-like sepals.
  • It is named after John C. Frémont, the American explorer and politician who collected botanical specimens during his expeditions through California in the 1840s.
  • The entire plant is covered in tiny star-shaped hairs that can cause severe skin and respiratory irritation — handled without protection it causes 'flannel disease.'
  • Flannel bush is drought-adapted to an extreme degree: summer water, especially around the roots, is often fatal, making it notoriously difficult to grow outside California.
  • The genus Fremontodendron has just two species, both native to California's chaparral — it is one of the most California-specific of all flowering shrub genera.
