Beech trees are notorious for hanging on to some of their dead leaves all winter. That trait is called marcescence (mar-SES-ents) . Beech trees do it; so do oaks. When I walk along the road on a windy day, I can hear the beech leaves rattle and shake. The other day I took a closer look at one of the beech leaves. It looked a bit like a stained glass window, but without colored glass.
Next time you're out walking
look for leaves lingering on limbs. Notice their shape and color, whether they have jaggedy edges, and what kind of tree they are on.
