Product Description:

The Ames St Johnswort, Hypericum kalmianum 'Ames', often commonly called Kalm St Johnswort, is an evergreen shrub or subshrub with upright branching that typically grows in a dense mound to 2-3’ tall. It is a neatly rounded garden shrub with dazzling golden yellow flowers in mid summer. 'Ames' is slightly hardier than the species and has a more uniform shape. Flowers give way to beaked, oval, brown seed capsules that mature in fall and often persist on the shrub until spring. 'Ames' St Johnswort is easily grown in average, medium, well-drained soils in full sun to part shade. It prefers moist, rich, sandy loams and tolerates some drought. Use as a low hedge, for shrub borders, rocky slopes, or a naturalized areas or pond peripheries.
