Looking for Canadian garden seed and plant sources online?
Listings are alphabetical by province and company.
This directory features Canadian seed sellers and online nurseries for seeds, plants, and bulbs. The listings are sorted by province so you can find sources in your region.
While I would like to list everything these individuals and companies sell, it is nearly impossible to keep on top of the changes, so please go directly to their sites for info.
While this started primarily as a seed company directory, there are also sources listed that sell plants and bulbs.
Personally, I want seeds, plants, and bulbs that do well in my zone, are not invasive, and benefit local wildlife.
