Mystery Tree Traditional Cache

Why did I bring you here? It seems like a regular alley in Toronto. It is because 50m north, on Harrison Avenue, a large Willow (Salix something) tree thrives where it seems out of place. How can it be here?

2024 Note: The tree is gone, but attached image shows it as it was

Also note, this is not a Mystery Cache

Increase your enjoyment by figuring out how that tree flourishes. Email the CO the answer if you want it checked.

Congratulations to Henry&Co for FTF and solve mystery, just edging out frenchyfaith by minutes.
