Black Sunflower Seeds
Does anyone know of a supplier of the black Peredovik sunflower, and is it open pollinated? All the seed offerd buy commercial agricultural merchants is F1, not much use to a seed saver.
Check some of the nurseries that sell organic and non GMO seed. Seed Saver's Exchange, Baker's Heirloom Seeds and Territorial Seed Company are some that immediately come to mind.
