MCPL Seed Library


About the Seed Library

MCPL Seed Library logoThis 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 is returned. Most our seeds are organic and GMO-free unless otherwise noted on the package.

Step 1: Borrow

Patrons may obtain 4 packets of seeds per visit. Patrons are limited to 20 packets of seeds per month. Please only take what you can grow in your space.  After you’ve made your selection, please visit the Adult Reference Desk and a librarian will check the seeds out to you. Our Seed Libraries are located in the adult public floors in both Centereach and Selden and can be accessed anytime the library is open.  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.

Current List of Seeds

Patrons should make an effort to save seeds. You can attend our gardening programs offered throughout the year to learn more. We also 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. You can also bring your seeds to our Annual Seed Exchange in March.

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. You can also visit the Seed Saver Exchange website or Hudson Valley Seed Company for more detailed directions.

Throughout the year, we’ll have programs on seed saving, pest control, and growing tips.

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.
