Hypericum olympicum L. Clusiaceae. Mount Olympus St John's wort. Deciduous perennial herb. Distribution Greece, Asia minor. This is not the plant used for mood disturbances in herbal medicine which is Hypericum perforatum. However, all the 370 species of Hypericum are called 'St John's Wort' so a potential for confusion exists. It shares some of the chemicals thought to be active in Hypericum perforatum. Photographed in the Medicinal Garden of the Royal College of Physicians, London.
