Fall is soon going to be here and that means time for Seedex donations.

Your seedex committee has been busy revamping the Seedex donation sheet.

Yes, we have eliminated the description column as most people found it cumbersome to look up and type in descriptions. When ordering seeds, members can always Google descriptions through the links we provide for every species or hybrid and it will relieve our proof readers of a lot of checking for spelling and punctuation.

Another feature is the addition of drop-down options from which you should select the relevant information. For colour, there are two columns which, for example, allows you to enter both pink and white if needed. The height in cm. and kind of plant like perennial or annual are also selected by clicking the appropriate box in the drop-down options.

Please play with the form before you are ready to donate.

The deadline for submitting your completed seed donation sheet is October 31. It should be emailed to This email address is being protected from spambots. You need JavaScript enabled to view it..

We would appreciate receiving your actual seeds by October 31, but any seed which is still not ripe by that time must be mailed no later than November 30. Seeds should be mailed or delivered to Arie Vanspronsen, 2 Union St, Box 1234, Waterdown ON, L0R 2H0. You can also deliver them to Carol Clark (Toronto, near TBG).


The ORG&HPS seed exchange is a major activity for our society, and the seedex depends completely on our members sending in seeds. By donating 5 items, you get preferred status when it comes to ordering, and you then get the pick of the crop which becomes a real bonus with some of the seeds which are in short supply.

We cannot accept seeds which are hydrophilic (recalcitrant)  https://onrockgarden.com/images/Seedex/HYDROPHILIC_SEEDS_WHICH_ARE_NOT_ACCEPTABLE_FOR_THE_SEEDEX.pdf

Please ensure that the seed is as clean as possible, free of contaminants, dried well and properly labelled and preferably in taped glassines which are available from Carol Clark or Arie Vanspronsen either by mail or pickup from them for a small fee. 50/$1 plus postage.
