Sharon said:Leon, seems that I remember them turning from shades of red to a golden yellow before falling to the ground. Is that what they do or is my memory just playing tricks? Looks like from your pictures that's what's happening. Beautiful.
Yes, they seem to transform from one shade and hue to another. I've taken pictures of them in varying stages of colors; and I "think" the frosts and cooler temperatures have something to do with it. (That's not a scientific fact- only a hunch!
) Maybe someone out there reading this can shed some light on it. In the picture below the leaves are mostly a golden yellow. But, note the ones at lower right which are in the crimson/red phase. I'm sure it has something to do with plant pigmentation and loss of chlorophyll: But exactly what I don't know. (Note the Sumac sapling poking through at bottom center.) In summary, your memory is not playing tricks.
