About Sunflowers

About Sunflowers

Sunflowers belong to the Helianthus genus, which contains about 70 species of annual and perennial flowers. The common sunflower, H. annuus, is perhaps the archetypical sunflower so often seen in gardens and landscapes.

Depending on the variety, these North and Central American natives stand up to eight feet tall. They have a strong, slightly hairy stem and coarse foliage.

Most sunflowers bloom in summer or into fall with dramatic yellow, orange, and red blossoms around a flat, central disk. Though the blooms may look like single flowers, they actually consist of many smaller flowers. The blossoms attract bees and other pollinators. Humans (and wildlife) treasure the plants’ tasty, oil-rich seeds.
