Asteraceae(family)
Forage for Pollinators: Nectar and Pollen is produced and foraged by Honeybees, Bumblebees both long and short-tongued, Solitary bees and flies. The pollen is especially sought after in autumn when there are few sources of pollen available. Sunflowers are rarely self-pollinated and most need pollen transferred to them from other sunflowers. Seed yield of sunflower crops is significantly increased by taking honeybee colonies to them. There are also extrafloral nectaries in bracts and upper leaves.
Flowering time: July, August, September.

Increasingly being grown here in the UK on field-scale for game cover and bird-seed, and this must be of great benefit to bees when organically grown.
