More Fall Color

Autumn continues its progress in Kalamazoo, despite the unseasonably warm weather. Silver maples seem to be at their peak (at least those growing by ponds & lakes); some have already lost their leaves but most are bright red. Sumac, Virginia Creeper, and Poison Ivy contribute more reds. There are a lot more yellow leaves-- walnuts, hickories, and ash-- than there were a couple of weeks ago. Some oaks are getting a little purple-red and the first sugar maples have started to change.

The National Arboretum has an interesting page on the science of color, which explains why day length, rather than temperature determines when leaves change.

West Michigan Weekly has updated their Fall Color Report.
