The Palos Verdes Peninsula Land Conservancy provides a list of the Top 25 Native Plants in the area, including many beautiful flowering plants. The Conservancy also offers tips on where to view or purchase native plants.
For a more comprehensive look at native plants, visit the California Native Plant Society (CNPS), a nonprofit that focuses on conservation, education, and horticultural use of native plants. The CNPS keeps a list of endangered plants, as well as an index of 7,095 plants native to California.
The index, called Calscape, also allows visitors to search based on a specific location in California. Search results are broken down into categories of plants, such as trees, bank stabilization plants, low-water plants, and easy-to-tend plants.

Non-Native Plants and Invasive Species
The California Department of Food and Agriculture, with the help of UC Davis, tracks noxious weeds through a program called Encycloweedia. The database helps users identify weeds by name and through pictures.
Californians can also report a pest here, and learn how to photograph or collect specimens properly.
On the federal level, the U.S. Department of Agriculture keeps a list of “Federal Noxious Weeds,” including introduced, invasive, and noxious plants.
