Cutleaf Coneflower (common along the canal near Harrison Street),
Boneset (shows up in sunny spots along creeks),
Cardinal Flower (along the banks of the Millstone River, upstream of Carnegie Lake),
Summersweet (also called Clethra or Sweet Pepperbush--very fragrant),
Swamp Milkweed (wet, sunny spots in local preserves, great for Monarch butterflies),
Monkey Flower (swamps).
