Fair enough.
When I originally thought of 'China Flowers' for the UK, I was thinking of flowers which are from China (not sure whether even possible with fresh ones, dried/artificial ones are probably possible though).
However, if you haven't already noticed, all the Google results are for Chinese florists or for compaines offering to deliver flowers to China. Not sure this would be any use on a UK extension.
All in my opinion of course and provided to hopefully give you some knowledge, but other opinions may differ.
