|Fremontodendron 'Ken Taylor'
(F. californicum × F. mexicanum')
Fremontia Torr. nom. illeg.
They are within the botanical family Malvaceae. Formerly they were treated within the Sterculiaceae, tribe Fremontodendreae, together with the genus Chiranthodendron. The genus Fremontodendron was named in dedication to John C. Frémont, who first collected it during an 1846 expedition to Alta California.
The leaves have a leathery and fuzzy texture reminiscent of flannel (thus the name), and the yellow to orange flowers are large and showy. The leaves and young shoots can cause skin and eye irritation.
There are three species:
- Fremontodendron californicum — Californian flannelbush
- Fremontodendron decumbens (R. Lloyd) — Pine Hill flannelbush
- A decumbent and low spreading form, 3 feet (0.91 m) in height and 6 feet (1.8 m) in width, has yellow-orange flowers, and is endemic to the Sierra Nevada foothills, nearly all of the individuals of this subspecies are found in the Pine Hill Ecological Reserve in El Dorado County. In nature it only grows in metal-rich gabbro soil, a red weathered soil of volcanic origin. It requires fire for seed germination, but with the nature reserve is near human settlements fire ecology is suppressed. It is a federally listed endangered species.
- Fremontodendron mexicanum — Mexican flannelbush
There are a number of populations of uncertain taxonomy status. They include:
- Fremontodendron californicum ssp. napensis — Napa fremontia
- The current Jepson manual does not recognize this subspecies, using Fremontodendron californicum, but the form is different enough that it is horticulturally recognized by this name. It is typically smaller and more open in form than the species, with much smaller leaves and flowers. It grows 6–15 feet (1.8–4.6 m) in height and 4–12 feet (1.2–3.7 m) in width.
Fremontodendrons are cultivated as ornamental plants. They are valued for their bright yellow flowers, produced over a long period on a rapidly growing shrub or small tree. They are tolerant of pruning for size or shaping. They are adapted to dry, poor soils in a summer-dry, warm, sunny climate. They may succumb to root rot in heavy clay soils and/or summer irrigation.
- Fremontodendron 'California Glory' — lemon-yellow flowers with a reddish tinge, grows 20 feet (6.1 m) in height by 20 feet (6.1 m) in width. It is the winner of the Award of Garden Merit from the California Horticultural Society in 1965, and received a First Class Certificate from the Royal Horticultural Society in 1967.
- Fremontodendron 'Ken Taylor' — golden flowers with a darker orange outside petals in the spring and summer, and grows to only 5 feet (1.5 m) in height by 8–10 feet (2.4–3.0 m) in width.
- Fremontodendron 'Dara's Gold' — golden flowers over a long period from late winter through early summer, grows 3 feet (0.91 m) in height by 6–8 feet (1.8–2.4 m) in width. A hybrid between Fremontodendron decumbens and Fremontodendron mexicanum.
