Of California's total plant population, 2,153 species, subspecies, and varieties are endemic and native to California alone, according to the 1993 Jepson Manual study. [4] This botanical diversity stems not only from the size of the state, but also its diverse topographies , climates, and soils (e.g. serpentine outcrops ).

The Endemic flora of the State of California — native plants found within its borders, and nowhere else in nature.; The largest area of the state is in the Mediterranean climate floristic region, within the California Floristic Province — with the greatest number of endemic plants in North America.
The California Floristic Province is a world biodiversity hotspot as defined by Conservation International, due to an unusually high concentration of endemic plants: approximately 8,000 plant species in the geographic region, and over 3,400 taxa limited to the CFP proper, as well as having lost over 70% of its primary vegetation. A biodiversity ...
Rosa californica, the California wildrose, [1] or California rose, is a species of rose native to the U.S. states of California and Oregon and the northern part of Baja California, Mexico. The plant is native to chaparral and woodlands and the Sierra Nevada foothills, and can survive drought, though it grows most abundantly in moist soils near ...
California also leads the nation in walnut production, producing 100 percent of all walnuts grown in the United States. [12] As a result of the trade war between the United States and China, farmers in California received about $76.3 million in federal subsidy payments from USDA, where some of the subsidies were received by walnut farmers. [13]

It grows in varied scrub and open habitats, including chaparral, arid grassland, and Creosote scrub. [2] It is found at elevations from 150–3,400 feet (46–1,036 m).
