We have three Wafer Ash (Ptelea trifoliata), aka "Money Tree." They are called that because the seed pods they produce resemble coins, and children used them as play money.
It is an understory tree, meaning you don't plant it in full sun because it needs some shade. It usually is multi-trunked and trying to make it into a single trunk tree is virtually impossible (believe me, I tried and was defeated!). Growth rate is moderate, so in 10 years you'll have a 12' tree more or less.
They are easy to grow. Basically, you plant them in a partly shaded spot, water deeply once a week until they get established, and then leave them alone. Don't fertilize, don't amend the soil before planting, and don't worry if the tree develops a really ugly caterpillar that looks like bird droppings. That is a Swallowtail butterfly caterpillar which won't harm the tree and will give you a gorgeous butterfly.
I see you are in 8b, so October, November would be a good time to plant a tree.
See if there isn't a private, non-big-box nursery near you that has a Wafer Ash for sale. What you are seeing at Home Depot may or may not be a true Wafer Ash (tags do get switched) and may not have been cared for properly. Also, if you have any questions after planting, the private nursery will be more willing and more able to answer your questions.
