Anyone grow it? Reports from Wye Plantation and Edible Landscaping both seem to indicate that it's an especially easy and long-lived variety.
I found an old thread that Creekweb had one.

I have a Tecumseh tree that's about seven years old. It's thought to be a Great Wall seedling, and the two are somewhat similar, but the Tecumseh ripens later, and the tree is faster growing and larger. I prefer my very prolific dwarf Great Wall. The Tecumseh and a number of my other persimmons were exposed to at least -11F this winter with only a sheet of ice for protection, so its survival is questionable."
