I’ve never been so aware of how many plants have stems and branches that turn red in fall. Even some of our wildflowers, that I would swear were green-stemmed spring, summer, and fall, turn out to turn red. I don’t think it’s climate change, or weird conditions. I think I’m just paying more attention, especially after having it pointed out to me a time or two. This is a beautiful example of the phenomenon.
I’m not sure why that phenomenon occurs, but it does quite often. There is a place near where I live that if you climb to a mountainside about 600 feet above the river and look down at it on a sunny day, the water appears an emerald green, but from other angles and places it appears normal.
