This is one of the few trees to present interesting bark year-round. Although more noticeable in the winter months, the vertical fissures of gray, brown, and black that form into plates are quite effective against a dark background. Not a good tree for fall foliage, though.
a Beautiful group of these trees are on the Ohio State University campus in columbus ohio. They are medium size here, probably because of the cold. They are also very difficult to find locally, but worth the search.

What's not to like about a tree that erupts in bell-like cream-colored flowers to announce Spring's arrival? The bark is interesting as well.
