Varieties Of Large Sunflowers

Sunflower heads produce seeds used for human and wildlife consumption.

Sunflower varieties differ in plant and flower size, and the preferred flower size differs depending on the intended use of the sunflower plant. For example, varieties raised for oil production commonly have heads about 4 inches in diameter, while sunflowers planted for ornamental purposes, or to produce seeds for human and wildlife production, often have larger heads and produce larger seeds. Does this Spark an idea?

The giant grey and mammoth Russian are two commonly grown sunflowers known for large heads and seed production.
