“Kalm’s St. John’s Wort is a small shrub topping out at just a few feet. Consider using it as a native hedge in a sunny, medium-moist site. ” –Prairie Moon Nursery “This dense, evergreen shrub is an absolute metropolis for pollinators once it flowers. Great as a container plant or in a sunny garden setting, this powerful little shrub makes a strong visual impression from moist open woods to wet lakesides.”
–Native Plant Trust
