- Description
-
Lemon balm is a bushy herbaceous perennial of the mint family that is typically grown in herb gardens and border fronts for its lemon-scented leaves. It was introduced from Europe and has naturalized throughout much of North America.
It prefers well-drained soils in sun to part shade but tolerates poor soils and drought once established. This plant will self-seed and spread aggressively by rhizomes, so it is best to grow in a container on a patio or deck where it is unlikely to escape into the landscape. Prune to remove spent flower stalks and encourage new growth for a better-looking plant. New leaves are more flavorful than mature ones.
Problems: Powdery mildew, leaf spot, leaf blight and gray mold may occur.
