Well, apparently I was right about this being the wrong forum... guess I'll kick it down.

No you started a good thread here.
Seeds of Diversity is the Canadian seed savers organization.
In the fall they put out a request for members to say which seeds they have.
The information is compiled into a print directory which is sent to all members in about January.
Members can then order seeds from those who have them. A nominal fee is to be sent---usually about $2.50 Canadian---- a little more for heavier seeds.
Seeds of Diversity also sponsors "Seedy Saturdays" and "Seedy Sundays" across Canada. There are usually small seed producers there with booths
selling seeds/and plants. There is a donation booth where we can drop off our excess seeds and pick up others that we might like.
There are presentations on sustainable topics. Saturday, March 19 is the Calgary one in the Montgomery community hall. There is one in Edmonton on Sunday, March 20. There is a nominal admission charge of about $2. to help with the hall rental.

Those dates in the previous post are Saturday, March 20 in Calgary and Sunday, March 21, in Edmonton this year 2010.

Another thing Seeds of Diversity does is they run a Canadian Tomato Project to preserve heirloom tomato varieties which were developed in Canada.

They also have a preservation project for other plants whee donors can donate money which is used to preserve seeds of some plant which is in danger of extinction.

Zeedman,
You posted in the right place. People come here and read posts all the time. I didn't respond because I knew once responded to, it would drop down the page.

Zeedman, I think you're looking for non-US groups. However, I only recently learned of some of the groups within the US and may be unfamiliar with others. Maybe we can list them, too. I'm also not sure just what qualifies as an organization so hope I'm okay listing this. Sandhill Preservation seeks out and grows many heirloom varieties and sells them at low cost. It is great fun to read about the varieties they have. I'm looking forward to growing a few of them myself this year and passing on seed to others.

Thank you, Xaroline, for the update on SoDC. I had considered joining them several years ago, but the sample rates at the time were too low to make it practical. Most of my collection is larger seeds (such as beans), and the cost of international postage would have been prohibitive. If the rates have been raised to the point where I can break even, I might reconsider.

I really like the "Seedy Saturdays" idea. At one point, I had considered trying to organize such a thing locally; but a new job has cut into much of my family time, so it may not happen.

Naturegirl, while my primary intent was to hear from international seed saving organizations, it would certainly be great to hear from other U.S. organizations as well. Glen (who runs Sandhill) is one of the founding members of SSE, and one of their advisors.

zeedman - I am not a member of any organisation and I am sure you already know of this one but here's a link below. (not specifically edibles).

Not stricly a seed organisation but this one is another plant conservation organisation. http://www.brogdale.org/

This site has some links too: http://www.gardenorganic.org.uk/hsl/hsl_links.php

Native Seeds/ SEARCH (Southwestern Endangered Aridland Resource Clearinghouse) is another excellent organization to explore. They are involved in the conservation and distribution of heirloom seed varieties (particularly those developed and utilized by cultures in the southwestern United States and in the northwestern portion of Mexico). Their website is: http://www.nativeseeds.org/.
