Anyone up to growing Paper Bush?

Another unusual plant I ordered from Woodlanders Nursery in S.C. was the Paper Bush
- Edgeworthia papyrifera

.
I planted it at the woodland's edge. I wish I had a stream I
could have put it next to, along with the Fetterbush, Virginia Sweetspire, and my
Hummingbird Sweet Pepperbush. The Paper Bush is surviving, but I have to pour the
water to it. It hates 100 degree weather, but I hear it loves the high humidity we
have in Central Alabama. It is not recommended for zones lower than zone 8.
I read that they grow it at the Missouri Botanical Garden, but I guess they grow it
inside.
