Hypericum frondosum, commonly known as Cedarglade St. Johnswort, is a deciduous subshrub or shrub native to cedar glades and rocky open woodlands in the Southeastern USA. It typically grows 0.6–3 meters (2–10 feet) in height and has a highly-branching form, creating a dense, rounded appearance. The stems are green when young, maturing to a reddish-brown with exfoliating bark that adds winter interest. From late May to August, it produces showy clusters of golden yellow flowers, each 25–45 mm (0.98–1.77 in) in diameter with five petals and a profusion of stamens, creating a striking contrast against the blue-green foliage.

Cedarglade St. Johnswort is valued for its drought tolerance, ease of maintenance, and the ornamental quality of its flowers and bark. It is often used in border plantings, naturalized areas, and as a foundation plant in residential landscapes. It thrives in full sun to part shade and prefers well-drained soils, tolerating a range of soil types from sandy to loamy. While it requires medium amounts of water, it can withstand periods of drought once established. Gardeners should be aware that it can be susceptible to root rot in poorly drained soils.CC BY-SA 4.0
