American Chestnut (in Canada)

While walking through the rock garden at the Royal Botanical Gardens in Burlington, Ontario I came across a small specimen of critically endangered American Chestnut. I wonder if it will survive the decade?

The chestnut blight (Cryphonectria parasitica) that decimated the once numerous American chestnut trees from 1904 to 1940 arrived in an era when urban forestry was in its infancy. The total number of chestnut trees in eastern North America was estimated at over three billion, and 25% of the trees in the Appalachian Mountains were American chestnut. The number of large surviving trees over 60 cm (24 in) in diameter within its former range is probably fewer than 100.
