Hypericum
Perennials and deciduous, semi-evergreen or evergreen sub-shrubs and shrubs, grown for their conspicuous yellow flowers with prominent stamens.
Fully to half-hardy. Large species and cultivars need sun or semi-shade, and fertile, not too dry soil. Smaller types, which are good in rock gardens, do best in full sun and well-drained soil.
