Yellow buckeye, a giant flowering tree of the Appalachians, comes down the mountain and does just fine away from the other mountain folk (mountain trees, in this case). Stately, showy, native, and shady.
If you have space to let it dominate and you want something a little different than typical shade trees, why not give this a try?
The yellow-green flowers are a well-documented source of nectar for hummingbirds and pollen for bees. We found an interesting website with ecoregional guides to pollinator plants. I read the Appalachian guide because that's our ecoregion, or nearly so, and, sure-enough, it listed Aesculus flava both as a pollinator plant AND a host plant for hummingbirds and bees. We read so much without sound sources (people just repeating each other), that I latch on to references like these and keep the pdf on my desktop. Here's the website link to the Pollinator Partnership ecoregion guides so you can do the same.
When you see the seeds, you'll immediately understand why it's called a buckeye tree - they aren't edible for you and me, but the squirrels love them!
Our plants are seedling grown by yours truly from seeds from Dr. Michael A. Dirr's garden.
We have two smaller buckeyes - the tree type Aesculus pavia (red buckeye) and the large shrub Aesculus parviflora (bottlebrush buckeye).
