Tall for a mint, 1 to 4 feet. Leaves toothed, pointed, opposite each other on the stem, and variable in shape from egg-shaped to oblong to lance-shaped. Stems square, rough or smooth. Flowers with a hood, two wings and a wide apron, rose purple with white streaks and blotches, in a loose spike.

A lovely native plant of meadows and roadsides that are somewhat shady and moist. Unknown in Wildwood until 2010 when it appeared along the Bikeway in the shadier parts of the South Meadow.

The square stems, opposite leaves, and irregular flowers are characteristic of the mint family. The unusual tallness and the exact shape and streaked coloration of the flower are good identifiers.
