The reason why osmanthus fragrans leaves turn red in June+10/October, 5438.

Because leaves are rich in chlorophyll, the temperature will drop slowly in autumn, and the production speed of leaf green will be slower than the decomposition speed, so the chlorophyll content in leaves will decrease.

However, anthocyanins in some leaves will increase rapidly, especially in cold and sunny conditions, anthocyanins will be produced more vigorously, so leaves will turn red.
