My golden queen got stopped at the border and came with a tag specifying that it was my "one time" allowance (ie, further shipments would be destroyed).
The (bare-rooted) tree died, but I was lucky enough to pluck off a couple of pieces of budwood as it was entering throes of death, and I now have a pretty large golden queen top worked on my keitt -- which is totally loaded with blooms right now.
I should get a pretty decent harvest of fruit this summer on it, and if it is indeed golden queen, I will make budwood available.
It appears to be a very vigorous tree, and has the odd characteristic of very thick stems -- almost comically large.
PS, mine was purchased under a different name, the taiwanese version of the name (Jin Huang).
