Abstract

St. John's wort is native to the temperate regions of Europe and Asia, but as with many other of our weeds, appears to have little significance in its natural habitat. In countries of its adoption, however, the story is very different. For example, in Canada and America it occurs over extensive areas of range land while in Australia it is proving a very serious weed.
