Oh, Hawthorn; what a tree. This tree has big thorns and beautiful fruit. This Hawthorn is what I call "on top of the world"; it lives on Mt. Pisgah on the Blueridge Parkway. There are many Hawthorns growing at this elevation. It is over 5,000 feet above sea level at Mt. Pisgah.
The late summer ID tip is to look for the berries and the one-inch thorns, and it is probably a hawthorn.
