favorite underused trees
We talk a lot about overused and/or invasive trees.
What are some of your favorite trees that SHOULD probably be planted more?
For me, here are a few:
Quercus michauxii - Swamp Chestnut Oak. I only really "discovered" this tree myself last year - I've known of its existence for a long time, but hadn't seen one in its full glory until last spring. Reasonably fast growth rate, often better-than-average fall color (can be a nice red, sometimes brown, almost as good as White Oak and better than Swamp White IMHO), nice form, good looking bark. Doesn't "need" a swamp to grow, but probably isn't quite as drought or urban tolerant than the "other" Swamp Oak, Q. bicolor.
Aesculus flava (sometimes called A. octandra) Yellow Buckeye - this tree is, IMHO, the best of the genus for most of us. Not nearly as scorch prone as the more commonly planted A. hippocastanum or A. glabra among the large-growing members of the genus. Has decent yellow flowers & often good yellow-orange fall color. Several large specimens in Baltimore showed no sign of scorch even as late as October this past season.
