California native plants are plants that existed in California prior to the arrival of European explorers and colonists in the late 18th century.
California also has 1,023 species of non-native plants, some now problematic invasive species such as yellow starthistle, that were introduced during the Spanish colonization, the California Gold Rush, and subsequent immigrations and import trading of the 18th, 19th and 20th centuries.f 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. This botanical diversity stems not only from the size of the state, but also its diverse topographies, climates, and soils (e.g. serpentine outcrops).
