Flower Sunday



No flowers today. It's fall. Here's some changing leaves from Lake Arrowhead, CA.
Now that the chlorophyll is moving down the trees from the leaves to the trunk, and, eventually, down to the roots, the leaves are beginning to die.

During fall, a process whereby the sugar forming in the leaves intensifies during warm days and then stops during cool nights, so that more and more sugar is accumulated in the leaves.

The abundant sugar causes the leaves to change color. By the time winter comes when the days are cool and the nights cold, the sugar then travels down the branches to the trunk and eventually to the roots, so that the leaves fall and die.

Happy raking.
