Hypericum is an evergreen shrub. It is a stoloniferous subshrub. It grows up to 1 feet tall. It is a fast growing plant. It has large, rose-like, five-petaled, yellow flowers (with five petals) having numerous, bushy stamens with reddish anthers. The flowers appear singly or in groups of 2-3 and cover the plant in summer. Oval to oblong, distinctively net-veined leaves are rich green in the sun but are a lighter, yellowish green in shade. The plant is used to control erosion on slopes, or to cover the bare ground under the big oak tree.
