BY Susan O’Brien In local parks and along our neighbourhood streets, the green leaf tones of summer are slowly giving way to lime tree yellows and orange tones of the chestnut. All around, there is a sense of a rising swell as flowers, fruits, and seed-heads surge towards a concert-like crescendo, in one final display. As the days become cooler and the evenings draw closer, most late season specimens will fade gracefully into the winter months.
