Hypericum is a genus of about 400 species of flowering plants in the family Clusiaceae, formerly often treated separately in their own family the Hypericaceae. The genus has a nearly world-wide distribution, missing only from tropical lowlands, deserts and arctic regions.
The species vary from small annual or perennial herbaceous plants 5-10 cm tall, to shrubs and small trees up to 12 m tall. The leaves are opposite, simple oval, 1-8 cm long, either deciduous or evergreen. The flowers vary from pale to dark yellow, and from 0.5-6 cm diameter, with five (rarely four) petals. The fruit is usually a dry capsule which splits to release the numerous small seeds; in some species it is fleshy and berry-like.
All members of the genus may be referred to as "St. John's worts" or St.John's-worts, though they are also commonly just called Hypericums; other names include Rose of Sharon and Tutsan. Some species are used as ornamental plants and have large, showy flowers.
