On native plants
I think there is a row of swamp roses along the west side of Willow Avenue along the Waterfront Trail. This row was reduced when the Guthrie building went in, but about a quarter of the row survives opposite TCAT. There is also a bed of swamp roses in a centre bed in a Cornell parking lot on the north side of Tower Road, near Stocking Hall. They have an unforgettable fragrance.
