SUNFLOWER

Sunflowers are annuals with showy, daisylike flowerheads that are usually 2-4 inches across and bright yellow.  Tall and course, the plants have creeping or tuberous roots and large, bristly leaves. Most sunflowers are remarkably tough and easy to grow as long as the soil is not waterlogged. Most are heat and drought tolerant. They make excellent cut flowers and many are attractive to bees and birds.

Sunflowers grow best in locations with full sun; they prefer long, hot summers to flower well.  If possible, put seeds in a spot that is sheltered from strong winds, perhaps along a fence or near a building.
