Seed Library
The San Mateo Public Library’s Seed Library offers free vegetable, herb, and California native flower seeds to San Mateo and Hillsborough residents. Visit the seed cabinet on the 2nd floor at the Main Library to choose some seeds to plant in your garden or containers! Mini-seed libraries will be available at the Marina and Hillsdale branches in June 2023. Limit of one packet per seed type per visit, and five packets total per visit. Seed types, growing tips, and lending guidelines are below—select tabs below to view information.

This project was supported in whole or in part by the U.S. Institute of Museum and Library Services under the provisions of the Library Services and Technology Act, administered in California by the State Librarian.
Mission
Planting from seed is a fulfilling adventure! Through the seed library, we hope to:
- Spark interest in learning how to garden and grow food. Anyone can do it!
- Foster an appreciation and enjoyment of nature, from soil organisms to plants to bees and birds.
- Encourage food self-sufficiency, both personally (growing your own food) as well as in community (harvesting and giving back organically-grown seeds to the seed library to further a sustainable cycle).
- Help preserve biodiversity, and increase populations of native pollinators (birds, hummingbirds, butterflies, bees, and insects) by planting native flowering plants that provide nectar and pollen, and refuge.
- Increase equity in our community—access to free seeds increases food security and food justice.
- Improve health—growing food in healthy soil can provide more nutrient-rich food than commercial farming.
- Respond to climate change—there’s nothing more local than harvesting from your own yard or balcony.
- Provide education on growing food, healthy soil, saving seeds, and related topics.
- Foster a sense of community among San Mateo’s “urban farmers”.
Welcome to the San Mateo Public Library’s Seed Library!
Lending policy
Seeds are free and available to residents of San Mateo or Hillsborough. No library card is required.
How much seed do I need?
Each packet contains enough seeds to grow a crop of that vegetable, herb, or flower for a season.
Help us provide seeds for everyone by following these guidelines:
- 1 packet maximum per type of seed per household per visit
- 5 packets of seeds total per household per visit
What kind of seeds do you offer?
Vegetable and herb seeds are organic, non-hybrid, non-GMO. Many are heirloom. Some flower seeds are organic; all flowers provide food and refuge for pollinators and most are drought-tolerant California natives. Our seeds come from Eden Brothers, Johnny’s Seeds, Botanical Interests, and Larner Seeds.
How do I plant these seeds?
Basic growing instructions are provided on the Growing Tips tab. Many seeds can be planted directly in the soil outdoors but some should be started indoors then transplanted (tomatoes, peppers, eggplant, for example). For more information on a specific type of seed, consult the seed company’s website, and the SF/San Mateo Master Gardeners’ website—which has a wealth of growing tips and techniques. Librarians can help you find books on growing vegetables, too.
Do you accept seed donations?
During this first year, we are not accepting seed donations. However, if you are interested in learning how to save seeds from your plants (or already know how), consider joining our future Seed Savers Brigade! In partnership with San Francisco/San Mateo Counties Master Gardeners, we will offer workshops on how to save seeds, and use these donations to continue the seed library. Email mbaute@cityofsanmateo.org for more information.
