What causes color variations?

9 years ago

Two Acer rubrum trees I found in out in the woods, growing within 3/4 mile of each other and look quite different in coloration, both in the fall and now in the spring. New leaves look greenish orange (more on the periphery with green center) and the other is almost a solid maroon color. Last fall was basically the same when fall colors hit. Are these genetic differences that happens among the same species? Does cross pollination create a sort of sub species with different charactaristics? I'm sure they're all just from native seeds falling from surrounding trees.

    It'll take someone with better botany skills than I have to answer your question. I take it you found them last fall and dug them this spring. It will be interesting to see if the maroon coloring is stable throughout the growing season and I hope you keep us posted.

    I've seen 3 trees like this out in the country, growing in a 'clump' similar to a birch tree, one or two would turn completely yellow in the fall and right next the other one would be one dark red.

    These two spent most of last season here in the ground. They both are coming back very well from winter. The Colors last fall were similar. Different as night and day. Same part of the yard btw.

    Just a follow up. The tree on the LEFT turned a nice peachy color but the dark red one on the RIGHT decided on different colors this year. Almost all yellow. The leaves at the very top, that came later in the season and haven't colored yet, look to have potential to turn deep red like last year. Different year, different colors I'm guessing.

    Edited 6:55 pm: had left and right transposed.

    Just in case anyone was wondering. :-)

    The little tree on the right never did put on a deep red display like it did it's first Fall or two. The larger maple tree on the left was removed for lack of interest and to make room for other placements in that part of the yard.

    Here's a picture of that little red maple today: (a bit windy for pictures)...

    Guessing 12-13 ft tall, maybe 1.5" diameter above the root flare.

    Now that's a Root flare:
