I've seen a few of this good tree species planted at arboretums in southeast Pennsylvania. Its native range in in the Appalachian Region of southwest Pennsylvania to northern Georgia and along the Ohio River to southcentral Indiana. It is hardly different from the more common Ohio Buckeye. It also has its compound leaves with 5 leaflets that turn orange in autumn. The erect terminal flower clusters are also yellow. The husk of the fruit capsule is different in that it is smooth, while the Ohio species has little bumps and spines on it. The Yellow species also likes moist or draining wet soil that is somewhat acid to slightly alkaline. It grows about 1 foot/year and lives about 150 to 250 years. It tolerates a little more shade than the Ohio species. It also can be hit hard some years with cool, wet springs by Leaf Blotch fungus disease, so many leaves darken and fall early in late summer.
