Grown for their striking and colorful flowers, Helianthus (Sunflowers) can be annuals or perennials, with coarse simple leaves and large, showy daisy blossoms. Extensive hybridizing has resulted in a great number of cultivars providing a wide range of colors (yellow, red, orange, creamy-white and bicolor), flower shapes (short or long rays, frilled or double), and sizes (dwarf to giant). Blooming from summer to fall, these showstoppers make outstanding cut flowers and are valuable additions to beds and borders. Loved by the artist Van Gogh and generations of children, Sunflowers are fun, easy to grow, and require little care.
