Fremontodendron mexicanum (Southern Flannel Bush) - A large evergreen shrub that can grow to 20 feet tall by as wide with velvety gray-green leaves with distinct 3 to 5 lobes and stellate hairs on the underside. These leaves only sparsely cover the branches so the plant is quite open when the great abundance of lemon-yellow flowers with a reddish tinge to the outside of the petals are displayed in the spring and summer. It does best in full sun with no supplementary water and is reliably hardy to about 15 ° F and perhaps as low as 10° F. The fuzz on the leaves can be very irritating to the skin, and protection should be worn for the eyes if a person needs to work with this plant. Fremontodendron mexicanum is rare and endangared in it natural habit which extends from the Laguna mountains of southern San Diego County south into northern Baja California where it can be found within the chaparral commmunity as well as among Tecate cypress trees (Hesperocyparis forbsii) in the coniferous forest. The name of the genus was named in combination with the Greek word 'dendron', meaning "tree", as a dedication to John Charles Frémont (1813-1890) who first collected Fremontodendron californicum during an 1846 expedition to Alta California. It was granted the Awarded of Merit from the Royal Horticultural Society in 1927. We have grown this great cultivar since 1982 and also grow Fremontodendron mexicanum, Fremontodendron 'Ken Taylor' and Fremontodendron 'Dara's Gold' The information on this webpage is based on research conducted about this plant in our nursery library, from online sources, as well as from observations made of it as it grows in the nursery in containers, in the nursery's garden and in other gardens where we have observed it growing. We will also incorporate comments received from others and welcome getting feedback from those who may have additional information, particularly if this information includes cultural information that would aid others in growing  Fremontodendron mexicanum.
