Kalm's St. John's Wort (Hypericum kalmianum)

A sun-loving, low-growing, 2 to 3 foot high, native shrub found in moist, low areas. The long-blooming, bright yellow summer flowers have showy, pompom-like stamens. Best used en masse for full effect.

The species and common names honor Peter Kalm, a student of Linnaeus, who discovered the plant in America around 1750. This is one of several shrubby St. John's Worts with yellow flowers and small axillary clusters of leaves.
