common sunflower
Native to much of North America, this is a wild California selection from the Central Valley just east of Lake Berryessa. A fast growing annual with coarse heart-shaped leaves and topped with an abundance of 3 inch flowers, with bright yellow petals and brown centers on branched stalks. An excellent habitat plant, providing nectar and pollen for a wide array of bees and butterflies as well as seed relished by birds. A highly variable species with a long history of uses and domestication. Plant in full sun where it is adaptable to soil types and watering regimes. Can manage in dryish conditions but best with moderate water, especially early in its growth.
