Why do Leaves Change Colour.?

In our autumn in Victoria, deciduous trees are a spectacular sight. In the streets, roads, avenues line with towering desidous. In our property, we planted several 18 years ago. Vibrant reds, oranges, yellows, and purples. capture the eye through a photographer's lens. We love driving into country roads where these golden ember colours draw us to want to know more about the mystery behind why their leaves change from reds and burgundy to golden orange, then bright tan, and eventually, fall? Thanks to Science of Botany. Green leaves are green because of the presence of the pigment chlorophyll, therefore photosynthesis happens. In temperate regions, cold winters affect the leaves of broadleaf trees and other perennials, and so these plants drop their leaves, gradually. As the declining day length and falling temperatures of autumn, leaf abscission ( the dropping of leaves) begins with the decomposition of chlorophyll. As the green fades, yellow and orange pigments, known as carotenoids show in the leaves. In other plants, pigments called anthocyanins accumulate in the leaves at this time, giving them shades of red and purple. Some of the most amazing fall foliage features both types of pigments, often with one color leading to the next as the season progresses. Eventually all the leaves drop. The desidous trees and shrubs go dormant for the long winter months. What do you think?
