The American Beech (Fagus grandifolia) is one of the few deciduous trees in Michigan to hold its leaves all winter. The leaves change color in autumn but rather than dropping they just slowly fade to tan on the branches. I'd never really thought about when they finally lose their leaves, but this week I noticed scattered beech leaves on top of the snow.
