Fremontodendron : Greenhouse Plants

FF – frost free only

Family: Sterculiaceae

SW USA and Mexico

Fremontodendron californicum is the species normally grown as a tender wall shrub outside. However, it makes an extremely good climber for the frost free house and will do much better with the added protection. Unpruned and planted out it will reach 4.5 m (15 ft) or more but smaller shrubs will flower well in pots. During spring the plant is covered with bright yellow flowers. After this first flush further flowers are produced and flowering will continue sporadically for the rest of the season. The semi evergreen nature of the plant guarantees that most of the attractive lobed hairy leaves will remain on the plant in winter under glass. This plant is easily raised from seed sown in spring at 18°C (65°F). Germination takes four to six weeks. Alternatively, cuttings 8-10 cm (3-4 in) long can be taken during summer. F. ‘Californian Glory’ is worth looking out for. It is a cross between F. californicum and F. mexicanum and has larger more richly coloured very plentiful blooms.
