Give us a guess in the comments, and we’ll be back to confirm!
These leaves are similar to maple leaves, but clearly maples don’t have berries. This is often called wild grape, a vine that tends to grow up trees, or grow up with trees, and flourishing their canopies. This vine is on a pine tree.
While we squirrels may appreciate the handy way the vine brings the grape fruits up to us, a vine growing a tree isn’t always good for the tree. It can overshadow the tree’s leaves and the extra weight is hard for a tree to support. Because of this, grape vines are often considered invasive, even though this is a native plant.
Now for a confession: We squirrels thought this was a native wild grape. But after consulting with Ms. Flora, we have learned it isn’t. Those pretty blue berries are the give away. They aren’t unripe grape fruits; that is what the fruits look like on a grape look-alike. (And we were caught by it, too!) This is a species native to China, Japan and other Asian countries known as Porcelain Berry, Amur Peppervine or sometimes just creeper. Ampelopsis glandulosa actually is invasive and we recommend that you do not eat them!
