many plants growing in a semi-natural area behind old Strubb's factory - could have been planted but there are no other plants here out of place. In "List of the Vascular Plants of Ontario's Carolinian Zone" this species is not listed for any County E of Elgin. Strangely there are a few locations for this species in Hamilton on iNat. No idea on the origin on these Hamilton plants. Adventive? Not sure how the Brantford plants got there but the population is robust at this location.
