About
Rhus ovata, commonly known as sugar bush or sugar sumac, is a shrub or small tree found growing in the canyons and slopes of the chaparral and related ecosystems in Southern California, Arizona, Baja California and Baja California Sur. It is a long lived-plant, up to 100 years, and has dense evergreen foliage that make it conspicuous. It is closely related to and hybridizes with the lemonade sumac.
Where it grows
The sugar bush is primarily located in inland localities, as it grades into its relative, the lemonade sumac, near the coast. However, it does occur on Santa Cruz and Catalina Island. It may be found throughout the inland mountains and foothills of Southern California, continuing southward through the Peninsular Ranges of San Diego County into northern Baja California, in the foothills and mountains of the Sierra de Juarez and the Sierra de San Pedro Martir. Further south, more disjunct distributions are found in the sky islands of the Central Desert of Baja California, primarily in the mountains of the Sierra La Asamblea and the Sierra San Borja. The southern limit occurs in Baja California Sur, on the Tres Virgenes volcano. The species is also found distantly in Arizona, on the Mogollon Rim.
