NANPS Seed Exchange
The 2024 – 2025 Seedex list
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 by:
- Growing native plants and offering some of their seed to our Exchange* or;
- Requesting seeds and planting them in your garden or;
- Both of the above!
The success of the NANPS Seed Exchange relies on your participation. See below for more information on how to donate and/or request seeds.
The Exchange is open to all members. If you are not yet a member, you may join online now or include your membership form with your seed request.
New to seed collecting or growing native plants from seed? Review NANPS’ guidelines for seed collection and indoor native seed stratification tips.
*Seeds are most often contributed from NANPS members’ gardens but donations of seed ethically collected from wild sources are also welcome (less than 10% from a healthy population of relatively common species, otherwise do not collect!). 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.
Seed Donation
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
Seed Requests and NANPS Seedex List
2024/2025 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).
Requests can be emailed to seeds@nanps.org or by mail to NANPS mailing address (see below). 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.
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.
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.
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
- Cheque or money order – please do not send cash in the mail.
Cheques can be mailed to:
