Hypericum is a large genus of flowering shrubs, ground covers and annuals with a worldwide distribution. Known for their ornamental flowers and foliage, most species of Hypericum are frost-resistant plants that can be grown in landscapes as border plants or ground covers. Most species of Hypericum can be grown in shaded or semi-shaded areas of the garden where they bloom profusely in spring or summer. The flowers are bright yellow or golden. A number of hybrids have been produced for their horticultural use.
Among many useful flowering shrubs and ground covers, my personal favorite is Hypericum calycinum which is a vigorous growing plant. Usually grown as ground cover or small shrub, this lovely bloomer produces bright yellow flowers in summer. The flowers are chactrized by a mass of showy stamens that make this flower look quite unusual. H. calycinum prefers bright sunlight and moderate watering. The plant is commonly known as Rose of Sharon.
