Ornamental Sunflower Information Sources
The National Sunflower Association works with commercially-produced (agricultural) sunflower grown by farmers for food, oil, and industrial purposes. Gardeners and consumers seeking information on growing ornamental sunflowers should consult with a local horticulturalist or gardening expert; a local plant nursery or nearest county extension office is a good place to start. To locate county extension offices in the U.S., see the web site: www.csrees.usda.gov/Extension/index.html
