red deadnettle, leather-leaf nettle, purple cat's tongue
Purple deadnettle is a common weed invader of vacant agricultural fields, landscape borders, derelict lawns, and compost piles. The leathery leaves often appear dark green-to-purple. Deadnettle is one of the first plants to flower after snow melt in the spring. Appearance in lawns will be linked to thin or bare areas that experienced some disturbance in the previous fall.
