Rose of Sharon

One of the best hypericums for ground cover, even on dry shaded banks, Rose of Sharon is a Bulgarian species which is easily naturalised in difficult sites and may eventually need control by chopping around plants with a spade to halt the creeping stems. It is a valuable and robust shrub with all-year interest and a long season of bloom, the large bright yellow star-shaped flowers with prominent red-tipped anthers making a sunny display for 4 months. Annually cutting stems to the ground reduces the risk of rust and improves flowering.
