By the end of the last ice age over 10,000 years ago, High Park would have been under 60 metres of water. As the water drained, large deposits of sand and other fine material were laid down here. The sand remains and, as a result, some sand-loving plants thrive.
Huckleberry thrives in old dunes and plains:
The Wild Lupine that was originally here was all picked and disappeared over time. In the last few years, it has been reintroduced and does well in this dry sandy soil:
Sassafras is uncommon in the Toronto area because there is not much of the dry sandy forest that it thrives on:
Sassafras is lovely in autumn:
It seems odd that a plant called Swamp Dewberry would grow in sandy High park. It is usually found in moist, shaded places but occasionally appears in dry forests like High Park:

Thank you Miles for explaining the disappearance of the Lupine… I always wondered why I could not find those hillsides blanketed in Lupine. I have tried to grow Lupine and now I realize the soil I provided was too rich.
Its nice to understand the ways of Nature. Thank you for your insights.
I very much enjoyed your nature walk!
Great birds, and now, great botany. Nothing like having it all! Thanks, Miles!
