A clump-forming, mint family member that grows 3 to 4 feet tall. The pinkish lavender, two-lipped, tubular shaped flowers appear in dense, rounded, terminal heads. The paired leaves arranged on square stems are scented. Loved by humming birds and bees. A good choice for naturalizing in a grassy area mixed with Rudbeckia and Joe-Pye weed. Grow in sun to part shade in well draining soil, tolerate dry conditions. Flowering mid to late summer. Not eaten by deer, but under dry conditions with humid air may develop powdery mildew, especially late in the growing season.
