The American mountain ash (sorbus americana) is a very attractive ornamental tree. It is not a true ash. It usually remains rather small, the example shown here being typical for the tree in this area.
The brilliant orange berries are attractive to birds and they remain on the tree deep into the winter, long after the leaves have fallen, or until the birds have finished them off!
Noting this tree today was a reminder of another orange fruit which will be ready soon, the persimmon! We have to have a frost, though, before that fruit is edible. And it sure hasn't felt like frost anytime recently, for sure.
