St John's wort - Hypericum perforatum subsp. veronense - Βαρσαμόχορτον - Cyprus

Hypericum perforatum, commonly known as St John's wort, is a flowering plant in the family Hypericaceae and the type species of the genus Hypericum. It is perennial that grows up to one metre tall, with many yellow flowers that have conspicuous black glands around their edges, long stamens, and three pistils. Probably a hybrid between close relatives H. attenuatum and H. maculatum that originated in Siberia, the species now has a cosmopolitan distribution. It is native to temperate regions across Eurasia and North Africa, and has been introduced to East Asia, Australia, New Zealand, and parts of North and South America. In many areas where it is not native, H. perforatum is considered a noxious weed. It densely covers open areas to the exclusion of native plants, and is poor grazing material. As such, methods for biocontrol have been introduced in an attempt to slow or reverse the spread of the species. From Wikipedia, the free encyclopedia
