Partial shade or sun. The thick, greyish leaves are large compared to other native skullcaps. Heartleaf skullcap spreads like a groundcover from fleshy rhizomes to form a low mass. Small purple-lavender flowers appear from April into July. It can remain somewhat evergreen in warm winters. Even if it freezes back, expect it to return robustly from the roots in spring.
None needed, except to contain it from spreading. Winter damage can be cut back in early spring.
