Seed Exchange



Prepare for the 2018-2019 Exchange

First, join ORG&HPS. You must be a member to participate in the seed exchange. 

Collect seeds from your garden this summer. All kinds of seeds are welcome - from alpines, border perennials, pond plants, shrubs, trees and wild flowers to edibles. "Mystery plants" also are welcome contributions. As you collect, make notes about the height and colour as well as the most correct name that you can find for the mother plant.

For a tutorial on seed collection, watch the video "Collecting Seed from Flowers and How to Clean Them" posted by Robert Pavlis on

You do not have to donate seed to participate, but remember, if a listing is in limited supply when we fill orders, donors receive preference over non-donors.

Instructions were sent to all members on September 29 for submitting the lists of seeds they plan to donate. Very early in December, everyone will receive the newsletter listing all of the seeds on offer.

At that time, you can select up to 60 packages of seed for just $15. Orders can be placed either on-line or through the mail. Orders must be placed by January 1, are filled in the first week of January and distributed about the middle of January.

Residents of the USA can order only those seeds approved for entry into your country. 
Restricted seeds are identified in our Seedex with the symbol [X] in the germination 
code. As well, USDA inspectors will reject any seed identified only as "sp." if even one
plant in its entire genus is considered endangered.

Please keep in mind that a Small Lots of Seed Permit is required and must be sent in 
with your order, along with the Conditions, an itemized list of the seed names, your
own mailing label and the yellow and green mailing label. If you have recently applied
for the permit, and expect it soon, you can send it later on.  USA regulations restrict
importation to 50 packets of seed, but if you fill in all 60 spaces, we'll stop when we
get to 50 if you were lucky enough to get all your wishes!
