One specimen growing well for ten years in south Louisiana.
Beautiful tree! Evergreen with gorgeous red new foliage. Flowers every year, sets some fruit, and then one after another the acorns seem to wither away. Disheartening. Forty feet away a Q. polymorpha is thriving in the same heavy acidic soil and produces many viable seeds yearly.
I am finally going to add mulch and fertilizer to the germana- hope that I don't jinx it.
Nov. 2016 finally- three mature acorns- huge- added photo
hundreds of fruits did not make it past 5/8" for unknown reasons- perhaps maturity of specimen?

There's an interesting feature of the acorns I noticed this year. Normally, an acorn contains two cotyledons, joined by a common shoot. Q. germana acorns are not like this. They do seem to have two cotyledons, but each has its own sprout. The leaf end of the sprout is at the center by the proximal end of the acorn. The root emerges out of the side of the acorn, diagonally outward and distally from the leaf end.
