Seed ExchangeThe NPA Seed Exchange

Each year, the Seed Exchange prepares and packages several hundred types of seed provided from the NPA Border at the Bellevue Botanical Garden and our members’ gardens.  All seed is welcome, whether familiar old standbys such as Aquilegia (Columbine) and Lathyrus (Sweet Pea) or the rarest of the rare.  One year, the Seed Exchange received an email from the Botany Department of a major California university saying we were the only source they had found in the entire U.S. for a particular seed they needed.

We try to supply quantities of seed equal to or greater than those given by the major seed houses at a greatly reduced price.  Seed is available for purchase by NPA members and nonmembers alike online and at all NPA lectures and plant sales. View this year's seed list.

Join a packing party.

Packing parties meet from September through January with a special session in early summer when the fresh Hellebore seed comes in. They’re a great way to learn more about plants.If you’d like to put your name on the email alert list for packing parties, click here to volunteer.

How to donate seed.

For each plant, cut seed stalks when ripe, place upside down in kraft paper grocery bags (never plastic), and fold the tops shut. Note on the outside of the bag the name of the plant (be as specific as possible), bloom color, date seed was collected and your name.  For delivery, contact the Seed Exchange or bring the seed to the September or November NPA meetings at the Center for Urban Horticulture.
