Most sunflowers are tall 8-15 ft; most have rough-hairy oval to heart shaped leaves; most have large flowerheads 8-12 in across; and most have yellow ray florets and purplish brown disk florets. The ray florets of sunflowers are sterile, and only the disk florets produce seeds. All the sunflower cultivars are fast-growing annuals, and many are rather rank coarse-textured plants.
