Ancient and Original Tree and Shrub Origin Listing

We now have a source listing showing the areas where the seeds were collected. It is far more detailed than just growth zones; we state the county to pinpoint seedling origins. Also stock grown from Ancient or Old Growth seed will be designated by (A). There is no price difference between non ancient and ancient stock seedlings. We are simply offering more choices for conservation authorities, parks and preserves.


Old age in a tree is a testament to adaptation.  These are the trees we want to tap for their genetic information.  These trees have definitely been lucky to avoid the bite of the ax when Ontario was clear cut by mid 1800’s.  But their longevity is a story of constantly changing and adapting to climate change, air pollution, soil pollution and degradation.  We need to bring their genetics forward to create resilient forests.

In Nature, nothing is perfect and everything is perfect. Trees are contorted, bent in weird ways, and they’re still beautiful.
