No one can deny that Autumn is a colourful time of year in this part of Canada and the eastern US. As deciduous trees get ready for the coming winter, their chlorophyll production ceases and the green slowly leaches out of a tree’s leaves. As the green disappears, the other colours in the leaves become present. These colours were always there, but the green chlorophyll masked them. It is the anthocyanin and carotenoids in the tree’s leaves which determine the colours that will flame forth in the fall once the chlorophyll is gone.
While it sounds like a complicated process, the beauty of it is clear to anyone who has taken a stroll in the fall to admire the changing colours of the trees. From yellow, to golden oranges, to fiery reds and browns, tree canopies are transformed. It is our last blast of colour before winter blankets everything in white. And you should go out and admire it, before it is gone.
Look for these brilliant colours from these trees;
