Carpinus caroliniana (American Hornbeam/Ironwood) 15-25ft; small tree with smooth slate-gray bark; nicely shaped shade tree; mature trunk has a "muscle-like" look.
I ordered one of these for my Dad as a father's day gift and even though I had it shipped to GA in early summer (it was out of dormancy), it has still put out new growth and already made progress, even in this first year. Plants that arrive and take off like that are the mark of good root systems which is what I have come to expect with Mail Order Natives.
nice size. nice root ball. very healthy
