I forget all about Poison Ivy after October and only think about it again when I see the new leaves in spring. Of course it is still there, leafless and dormant. Pictured above and below is the bud and a few remaining berries of a large vine.
Below is the “trunk” of Poison Ivy climbing a tree. Poison Ivy vines are often described as hairy, in this case the hair like rootlets that hold the vine to the tree are few and not obvious from a distance.
