Spring
The sugar maple flowers emerge in the spring, producing fruits that ripen in September or October. The fruits called samaras or "maple keys" contain a pair of seeds attached to a wing of flat tissue. Seeds germinate in the spring following their dispersal in the fall. The spring stamp, issued on April 14, 1971, shows a maple key in early spring prior to germination.

Autumn
In the autumn, shorter days and cooler nights trigger maple leaves to turn to brilliant shades of yellow, red, or orange. This spectacular colour show precedes the shedding of a tree's leaves before winter sets in. A fallen red maple leaf is featured on the autumn stamp issued on September 3, 1971.
