Dwarf Sunflower ‘Incredible’ grows to just 40 inches tall, and the yellow flowers can be up to 9 inches across. Plants are branching and have large leaves. Once flowers are spent, leave the seed heads for seed-eating birds such as goldfinches, cardinals, chickadees and jays. This sunflower is easy-to-grow and recommended for beds and borders as well as large containers. Prefers sunny locations.
