About plant names...

Wingstem, a member of the sprawling aster family, is a North American native plant.

Identification: Plants are 3-10' (91-304 cm) in height, hairy, with a four-winged stem. Leaves are alternate, narrowly elliptic, narrowly oval, or oval. They are 4-10" (10-25 cm) in length, rough-textured, sessile or with a short petiole, and usually toothed.
