Answer: Agrostemma is the common Corn Cockle, an annual or biennial (depending upon your winter weather), that grows to about 3 feet high with 4-inch long leaves, and flowers that are 3 inches in diameter, deep purplish pink lined and spotted with deep purple and centered with a white eye. These plants grow along roadsides and all parts of the plant are poisonous if consumed. Corn Cockle seeds are not widely available; they're considered weeds in many parts of the country. Galeopsis is the Hemp Nettle, a weed that naturalizes in waste places.While the flowers of both these plants are attractive, the plants themselves are weedy.
