Also known as Kalm’s St. John’s Wort, this plant is a small, tight-bushed shrub with brilliant yellow flowers, that blooms mid to late summer. Makes a nice border shrub along fence rows or walkways. Tolerates some drought but prefers a medium level of moisture. Native to the Great lakes and grows on sandy beach soils and dry open woodland soil. Flowers turn into brown seed capsules in the fall.
We also sell Shrubby St. John’s Wort, which is a taller shrub.
