Our unheated winter greenhouse that we grow year-round zone 5
Canada has a widespread difference in weather and seasonal trends. If you can find a local seed company that’s growing in a similar climate to you, the plants are adapted to your region. This can be especially important if you’re in a cold short growing season.
I will say that many of the Canadian seed companies that I have purchased from sadly seem to have gone out of business. We had a great local seed company Stellar Seeds for example. I couldn’t find the Cottage Gardener anymore either. I’ve only grown seeds from a small amount of Canadian seeds, but I tried to find as many as I could. I couldn’t find any seed companies for the northern Canadian territories ( I tried!).

Our weather is winter for many months of the year, we deal with snow, frosts and even drought and wildfires these days. I’m in a growing zone 5, but many others are in colder like zone 2 or 3. Some coastal areas like Vancouver and the Island get a lot of rain and but less heat. Nova Scotia and the east coast gets lots of fog and winter precipitation.

Because I live in B.C. I personally grow a lot from West Coast Seeds. It was there gardening guide (free) that helped my gardener gardener self over 10 years ago. I’ve shared some of my fav seed companies before, but today I wanted to focus on Canada. I also grow a lot from U.S companies because the majority of my readers are from the U.S. and I like to share certain varieties. But it’s great to support seeds from your local area.
