| Abstract | St. Johnswort (Hypericum perforatum), also called Klamath weed and goatweed, was introduced from Europe and was found in California about 1900. It was a major pasture weed west of the Cascade mountains from Tacoma south to central California until the successful introduction of the chrysolina beetle, a leaf-eating insect. |
