Hypericum kalmianum (Kalm St. Johns Wort)

Compact and easy to grow, Hypericum kalmianum (Kalm St. John's Wort) is a small semi-evergreen shrub with showy, golden yellow flowers blooming for about 6 weeks in mid to late summer. They are borne in flat clusters of 3-7 flowers, at the tips of upright branching stems. Each cup-shaped flower presents 5 petals surrounding a prominent tuft of golden stamens. Rich in nectar, they are a favorite of butterflies, bumblebees, or other pollinators and are excellent for cutting. They are followed by chocolate, oval seed heads in fall, which often persist until spring, but are of limited ornamental interest. The foliage of linear dark blue-green leaves provides a lovely backdrop for the bright golden blossoms.
