NANPS Seed Exchange

If you are donating seeds, please remember to:

• provide botanical and common name
• provide source information if known
• write clearly and legibly

Genetic provenance is an important consideration when selecting seeds from the seed exchange and whatever information you are able to provide about the origin of your seed is appreciated.

Donated native plant seed with provenance noted should be sent to:

Seed Exchange

NANPS: North American Native Plant Society
PO Box 69070
St. Clair PO
Toronto, ON
M4T 3A1

Please note that seed donors are permitted to request 30 packets of seed, which is twice the maximum amount for non-donors. Review the list in the section below for seed availability.

Inquiries about how the seed exchange works, or how to unlock the dormancy mechanism for seed offered, can be made to: seeds@nanps.org

2023/2024 NANPS Seedex List

The following native species are available to members through the NANPS Seed Exchange. Members can order 15 packets of seeds without having donated (seed donors may request up to 30 packets).

Members are asked to send their seed requests to seeds@nanps.org or mail to the NANPS address at the bottom of page. The seed exchange winds down by the end of March and resumes again in the fall.

It is not our intention to generate revenue from the seed exchange, but there is a small charge for each packet to cover the costs of packaging and mailing. Additional details and ordering instructions can be found below the Seedex list.

Please note that while all seeds donated are native to North America, they may not be local to the donor. Use your own discretion when ordering seeds and choose local stock if available. We recommend that members order seed that originates from their bioregion (the general rule of thumb is within a 200-kilometre range, or 125 miles). The same species grown at different locations will be listed separately, so that members can select the seed source closest to where they live.

NANPS tries its best to list seeds as received. NANPS also uses discretion when receiving seeds of threatened species.

Our donors are our heroes!

Please include the following information with your request for seeds: your name and mailing address, the species you’d like (by botanical name) and any substitutions you would like in case we cannot supply your first choice. If you prefer seed from a specific listed location please so indicate and we’ll try to comply.

 The cost of seeds:

If you are a Canadian requester include $2 for the first packet and 50 cents for each additional packet. 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 send $20 to cover the cost of a phytosanitary certificate (required to ship across the border) and 50 cents for each packet of seeds (in U.S. funds). Tree, shrub, and vine seeds cannot be sent to the U.S.

Payment can be made either by:

• e-transfer to treasurer@nanps.org and email seeds@nanps.org to let us know your request.
