This self-seeding overwintering annual or biennial is native to Europe and North America. A very drought tolerant herb, it bravely produces yellow mucilaginous bloom after bloom at night, even if baked by the sun during the day. The plant prefers sun to part shade and its flowers make an excellent addition to salads. Scatter seed on the surface of disturbed soil in the fall or early spring, or press into the surface of a flat, allow to germinate, and transplant the seedlings. The seed requires exposure to light in order to germinate, and the plants prefer to be spaced about a foot apart.
