Shrubby St. Johnswort
Clusiaceae (St. John's-Wort Family)
Shrubby St. John’s-wort is a very small, mound-shaped,
deciduous shrub, to 3 ft. tall, with dense, upright branching and exfoliating, red to purple bark. Smooth, dark- to blue-green, fine-textured foliage becomes yellow-green in fall. Large, yellow flowers occur singly or in few-flowered clusters. A dry, dehiscent, three-valved
capsule persists all winter.
This
shrub adapts to a variety of moisture regimes and is even flood tolerant. It has no serious disease or insect problems. This species is pH adaptable but does extremely well in calcareous sites.
