Seed Bank in Ames, Iowa
Sunflowers being grown out are kept in insect-prooof bags to prevent cross pollination, at the USDA-ARS North Central Regional Plant Introduction Station in Ames, Iowa.
Seeds must be grown out periodically to keep them viable, one of the issues that makes proper maintenance of a seed bank difficult and expensive.
