NANPS Seed Exchange

The 2020 – 2021 Seedex list

Our Seedex is a benefit of membership. There are usually some seeds remaining after our member requests have been fulfilled, and we bring these seeds to events where we have an information table, such as Seedy Saturday. Because we cannot meet in person this year, we have now opened up our Seedex to the general public.

The cost of seeds are:
Member: $2 for the first packet and 50 cents for each packet thereafter. You can request up to 15 packets. Members who have already made a request are able to make another request up to 15 packets. If you are requesting acorns/nuts of tree species please add an extra $2 to cover the cost of mailing. If you are an American requester please contact Tree and shrub seeds cannot be sent to the U.S.

General Public: $3 per packet plus a $3 handling fee. You can request up to 15 packets.

All revenue goes toward the running of our charitable organization.

Payment can be made either by
-e-transfer to Let us know the species you are requesting and your mailing address by email,

-Cheque or money order – please do not send cash in the mail.

The NANPS seed exchange started in 1988 and has been running continuously ever since. There are over 10,000 species of vascular plants native to temperate North America. Our seed exchange offers you the chance to increase the population of a few of these. Please help North American flora to flourish by growing locally native plants in your own garden and offering some of their seed to our Exchange.

Seeds are most often contributed from NANPS members’ gardens but donations of seed ethically collected (less than 10% from a healthy population of relatively common species; otherwise do not collect!) from wild sources is also welcome. Once seed is sent to us we endeavour to store it appropriately (e.g. moist medium for hydrophilic seed, refrigeration at the appropriate time). We are only able to do this after the seed is mailed to us.
