St. John's Wort (Hypericum)

St. John's Wort Plant Features

Beautiful dark green foliage and bright yellow, buttercup-like flowers make St. John's wort a top pick for partially sunny landscapes. This fast-growing, low shrub thrives in even the poorest soil, quickly forming a solid mat of sturdy stems. St. John's wort grows 12 to 18 inches tall and is semi-evergreen in the southern part of its range. Once established, the plant is drought resistant. It's an ideal ground cover for hard-to-plant slopes and hillsides. Hardy from zones 5-9.
