MCPL Seed Library


About the Seed Library

The 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.

Step 1: Borrow

MCPL cardholders may obtain four packets of seeds per month. After you’ve made your selection, please visit the Adult Reference Desk with your library card and let a librarian know which seeds you’ll be borrowing. For a current list of our seeds, click here.

Patrons should make  an effort to save seeds. If you’re a beginner gardener, please attend one of our seed saving programs. See our Program Guide for a list of upcoming programs. We also have have a large selection of seed saving books you can check out!  All gardeners should maintain good records and make sure everything is labeled when returning seeds.

Remember Seed Saving is fun and a rewarding experience!

Step 2: Plant & Learn 

Now for the fun part: growing! Each packet is labeled with basic directions on how to grow the seeds. Please, visit our Adult Reference Desk to obtain more extensive directions on growing and saving seeds.

Throughout the year, we’ll have programs on seed saving, pest control, and growing tips. Visit the Adult Reference Desk or register online for these great programs. By borrowing seeds you’ll automatically be signed up for our MCPL Seed Library Newsletter that will contain growing tips, upcoming gardening programs and new seeds available in our Seed Library.

Step 3: Return & Share

Collect seeds from your healthiest or tastiest crops. Seed saving envelopes are available at the Adult Reference Desk. You can also download and print our Seed Labels. Please, include as much information about the crop as possible. The success of our seed library depends on good record-keeping. Seeds can be returned to the Adult Reference Desk at any time.

You can also bring your saved seed to our Annual Seed Swap in March.
