Description

Annual Sunflower (Helianthus annuus) is common and widespread. It is a native and in the case of many varieties, a domesticated crop. In some areas it is so prolific it is considered a roadside weed. It is common in open sites in many different habitats throughout North America, southern Canada, and Mexico. Annual sunflower should not be confused with the large, cultivated, edible varieties.

The name “Helianthus” comes from the Greek helios anthos, meaning “sun flower”, the species name annuus means “annual.”

Sunflowers need full sun. They are especially prominent along roadsides and disturbed areas, making them a good ingredient for reclamation and stablilization mixes. Sunflowers are an important species for wildlife habitat improvement, especially for birds. Annual Sunflower is a common component in pollinator mixes.
