Sourwood is usually found along ridge tops and upper slopes capped with sandstone, although it thrives on more favored soil sites as well. Large specimens have been observed growing in coves and richer slopes mixed with tuliptree, chestnut oak, hickory, and red oak. Sourwood, sumac, black tupelo, scarlet oak, and sassafras are the major sources of red color fall color in the Ohio landscape.
