Pycnanthemum tenuifolium is a narrow-leaved species of mountain mint with an upright habit reaching up to 3' tall and growing about 2' wide. Blooms are small, white clusters and while attractive, what really is noticeable is how much this plant attracts animals of all kinds! A favorite for native bee species, it is swarming with insects as it blooms in June through August. Slender mountain mint has a much more fine texture than Pycnanthemum muticum which allows a nice play of textures in the garden. Like other Pycnanthemum, this plant has a minty aroma when the leaves are crushed. Growing well in medium-wet to medium-dry soils in full sun to part sun, Pycnanthemum tenuifolium is adaptable, hardy, and an interesting plant in the border, meadow, herb garden, or naturalized areas such as areas near streams.
