American mountain mint

Pycnanthemum virginianum (American mountain mint) is a 3-foot tall perennial topped with dense clusters of white flowers in summer that attract a multitude of bees, flies, and other pollinators. 

The entire plant, but most especially its foliage, gives off a strong minty aroma when crushed or bruised. American mountain mint puts up thin, branching stalks from an expanding base. Each hairy stalk has whorls of thin, needle-like leaves that make for a bushy appearance by late spring.
