Mammoth Grey Stripe Sunflower - The Friendly Giant of Your Garden

This sunflower is grown for its edible seeds. Huge single flowers 10-12" wide grow on 10-12' stalks. Makes an excellent background plant for your garden, providing a valuable seed crop for songbirds and a tasty snack for people.


The wild sunflower is native to North America but commercialization of the plant took place in Russia. It was only recently that the sunflower plant returned to North America to become a cultivated crop. Sunflower was a common crop among American Indian tribes throughout North America. Evidence suggests that the plant was cultivated by Indians in present-day Arizona and New Mexico about 3000 BC. Some archaeologists suggest that sunflower may have been domesticated before corn.

Growing Tip

Larger sunflowers will penetrate deep into the soil. If you use drip-irrigation in your garden, make sure to place drip-lines away from the roots, the roots can puncture it.
