Non-Native Plants of Southern California Sorted By Commonness

See The Most Common Non-Native Plants of Southern California for an introduction to this page, and important caveats about this list.

This table presents all the 608 non-native taxa found in at least one plant trail guide or digitized flora. The taxa are sorted in declining order of the number of guides and floras that contain each taxa.

Keep in mind that this list simply counts the number of lists in which at least one specimen of each taxa occurs. The abundance of these taxa may be quite different from that count.
