The Seed Library at the Chicago Botanic Garden's Lenhardt library provides an opportunity for library visitors to “borrow” seeds to plant, grow, harvest, and save seeds for themselves and for return to the seed library for others to borrow the following season. By offering free open-pollinated seeds with instructions on the growing cycle, borrowers become a part of the community of seed savers with shared knowledge to pass on to future generations of gardeners. This poster will do a deep dive into our seed library and offer practical steps to easily replicate at other institutions.
