Seeds carry memory, it’s our job to preserve the story.
The Seed Swap Co-Op is a curated seed exchange designed to preserve plant lineage while connecting growers across regions. Members complete a short profile sharing what they grow, what they're seeking, and the environment they're growing in. From there, Calidad thoughtfully matches participants and facilitates the exchange, pairing seeds and stories with intention. Mail in what you can share. Receive what you've been hoping to grow. This is community-powered biodiversity.
