Plant Description

This St. Johnswort is a widely occurring shrub found throughout the eastern United States in dryish, rocky, sometimes calcareous soils. It forms densely branched mounds 2 to 4 feet tall and wide. Leaves are narrow, long, blue-green, and fall off in the fall with no additional color. Bright yellow, puffy, 1 inch flowers occur all summer long. Shrubby St. Johnswort will tolerate fairly poor but well-drained soils in full sun or light shade. It would be very effective as a hedge (trim in winter or early spring as flowering occurs on new growth) or where long term summer color is needed in a difficult bright spot. An added benefit is the dried fruit capsules which are shiney, dark brown and oval-pointed. They are produced in profusion and are effective from September to March. This Hypericum is very useful and definitely under-used.
