Kalm St. John's Wort Sunny Boulevard®, Hypericum x 'Deppe' PP20045, CBR#3587
Free-flowering, Hypericum kalmianum Sunny Boulevard® (Kalm St. John’s Wort) (Kalm St. John’s Wort) is a compact, tightly branched, rounded shrub with showy, rich yellow flowers from mid to late summer. While small, they are produced in such quantities that they cover the plant. Each cup-shaped flower presents 5 petals surrounding a prominent tuft of golden stamens. Rich in nectar, they are a favorite of butterflies, bumblebees, and other pollinators. The foliage of willow-like dark green leaves provides a lovely backdrop for the bright golden blossoms. This deer-resistant little shrub is perfect for adding bright summer color to the garden.
