Seed Library

Contra Costa County Seed Library

Seed libraries available at some branches, while varied in their use, are places for community members to share and trade seeds that have been donated or harvested locally. This means that the plants that grow from these seeds will often do better than store-bought seeds since they have acclimated to the local microclimates and soils. See the list below to find out where you can "borrow" and donate seeds.

The Seed Circle is open to all. Browse through our seed collection and take only what you need, leaving seeds for others. Seed envelopes are provided. Community donations of heirloom seeds are always welcome, either store-bought or self-harvested. Every spring we host a Seed Swap along with localized gardening programs to provide resources and foster connection between gardeners in the area.
