This is a large tree that bears clusters of berries that ripen in autumn. As you can see, the berries hold until dry. They tend to drop in late November and December, providing food for deer.
Are they yellow in summer? if so, see if it could be a chinaberry tree.
My guess would be ….
Phellodendron amurense the Amur cork tree
Opposite or alternate? I tried zooming in but its not immediately obvious to me (which suggests alternate). The prominent warty lenticels are a good clue. What is the structure of the fruit like? Winter buds would be helpful too.
I think you nailed it. Bark looks right, both the outer bark and the bright yellow inner bark. Fruit looks right. Buds appear opposite, separated by roughly 2-3" on the shoot, which seems right. The fruit have a citrus smell, which is right. Vegetation is reportedly not eaten by deer, which would explain why there are so many young ones around. I have pictures that substantiate all these points, but I think the question is answered. Thanks.
Reportedly, this species was introduced to the U.S. in the 1850s and it has proven invasive. MA classifies it as a “noxious weed.” Young ones here grow in thickets, presumably due either to seeds or root suckers sprouting.
Deer definitely eat the fruit. I can reliably find bug bucks under the trees in the afternoon in late November and December. I was thinking I should plant more of them. Now that seems a very bad idea.
Never heard of it. But it seem to have some biomedical uses.
