Invasive species in California, the introduced species of fauna−animals and flora−plants that are established and have naturalized within California. Native plants and animals can become threatened endangered species from the spread of invasive species in natural habitats and/or developed areas (e.g. agriculture, transport, settlement).
A list of invasive plant species in California. Numerous plants have been introduced to the California Floristic Province and within the state's borders. Many of them have become invasive species and/or noxious weeds. The following are some of these species:
The leaves are opposite, simple, ovate or oblong, 7.5 to 20 centimetres (3.0 to 7.9 in) long and 2.5 to 10 centimetres (0.98 to 3.94 in) broad, with a petiole 2 centimetres (0.79 in) long, and an entire margin; they are hairless above, and finely downy below, particularly along the veins, and turn yellow in fall.
