Good geusses all.
Here are some facts about this tree to maybe help.
This tree is the only plant in the Genus. It had gone out of cultivation, but was reintroduced from China. Hardy in zones 6 & 7. It is somewhat available in the nursery trade, however it has been cultivated in Europe far longer than the US.
It produces many small white to yellowish blooms on current years growth. It is typically a large shrub, but could grow into a tree of 50' with age.
There are a couple well recognized Arboreteum that have them in the collection. From what I have seen of this tree it could become a very good street tree option or small ornamental option. No pest or disease issues yet, does not appear to be invasive so far.
