Description

Black-Eyed Susan is a stiff, upright annual or short lived native to the eastern United States, but has become endemic throughout North America. In NC it grows as a biennial that may grow to 4 feet tall. The leaves are alternate with toothed or almost a smooth margin. Some leaves may have 3 or more lobes. The characteristic brown, domed center is surrounded by bright yellow ray florets (sometimes orange) which first mature in mid summer and continue into mid fall. This is a true sunshine worshipper that forgives neglect and has moderate drought tolerance.The trick to growing black-eyed Susan is to give it full sun in decent soil. Moderate fertility will give you the best flower show so avoid the edges of lawns where lawn fertilizer will provide excess nitrogen.
