Discussion
Carpenteria californica is a fire-adapted shrub endemic to the central and southern Sierra Nevada Foothills between the Kings and San Joaquin rivers, Fresno County (R. Casamajor 1950). Rare in the wild, it has a long history of cultivation in both Europe and the United States, including elsewhere in California (N. H. Cheatham 1974), where it is prized for its lightly scented, showy flowers and attractive, persistent foliage. The plant does well in sunny or partially shaded, sheltered sites with well-drained soils.
