Compact deciduous rounded shrub with an erect habit and poufy, pom-pom like showy flowers.  Red to purple exfoliating bark that reveals attractive pale orange inner bark.  Grows naturally on margins of swamps and bogs and on sandy or rocky ledges and in open woods.  One of the hardiest and most adaptable Hypericums.  Good plant for difficult situations.  More susceptible to root diseases in wet years if planted in heavy clay.   Valuable source of pollen for bees.
