MCPL Seed Library


About the Seed Library

MCPL Seed Library logoThe practice of saving seeds has been around for 12,000 years. However with the increase of biodiversity, this practice has been lost. This mission of the MCPL Seed Library is to collect, grow and share seeds with the community. The MCPL Seed Library contains a selection of vegetable, herb and flower seeds. Our selection changes throughout the year based on donations what what is returned. All our seeds are 100% organic and GMO-free unless otherwise noted on the package.
