One of Nature’s Mysteries to Solve

Hey there! I have a plain little leaf to show for today. A tough one, I know. So I thought if you don’t want to try an identification, make a guess as to why the leaf is colored like this! (That was Miz Flora’s idea.)


This leaf is from the Serviceberry, Amelanchier alnifolia. This small native tree can be a single stemmed tree, but also turns up in yards around here as a shrub.

It has a nice spring flower that I’ll remind Nutmeg to show you next spring. The berries disappear very fast—birds, you know—so I’m not sure we’ll be able to show them.

As for the leaf coloring, Miz Flora needs to answer that one.

“Simple really. Leaves are green with chlorophyll when they are making sugars—photosynthesizing. This leaf has shut down for the winter and is pulling its sugars in to store them. The green coloring goes too, along the veins, and the last little bit hasn’t finished being sucked out of the leaf yet.”

Uh, yeah. Hope some of you got that!
