 Motherwort (Creeping Jenny)
Leonurus cardiaca
Mint family (Lamiaceae)

Blooms July
- September

The non-native (Eurasian) Motherwort is common in our area. It prefers partial sun and moist fertile soil. Habitats include open disturbed woodlands, areas along woodland paths and borders, and edges of yards underneath trees. This perennial grows to 2-5' tall with heavily ridged square stems. The lower opposite maple-like leaves are up to 4" long and 3" across with several coarse teeth. The upper leaves are oval-shaped with a pair of coarse teeth, nearly hairless and have conspicuous veins along the upper surface. Whorls of stalkless flowers occur above the axils of the opposite leaves on the middle to upper stems. Each tubular lavender mint blossom is 2-lipped and about 1/3" long. The upper 'hood' lip can be very hairy on top. There are usually purple dots on the lower lipThe  green calyx at the base of the blossom has 5 sharp-pointed teeth.

Note: This plant is sometimes called "Creeping Jenny" by some which is confusing because Moneywort (Lysimachia nummularia) is also called "Creeping Jenny" by others.
