Coarse, sturdy plants grown for their familiar, colorful blooms in summer and fall. Most are prime subjects for cut flowers. Plants are tough and widely adapted. Perennial kinds spread rapidly and may become invasive. Tall sunflowers may need staking.
The wild ancestor of today’s familiar sunflowers is a coarse, hairy plant with 2–3-in.-wide flowers, native to much of the central United States and southward to Central America. It is the state flower of Kansas and the only plant native to the lower 48 states to have become an important agricultural commodity. It has been bred to produce giant plants as well as a host of smaller (but still significant) varieties for garden decoration and cut flowers. Most sunflowers used in gardens are 3 to 7 ft. tall.
