I know of nurseries in Britain that export growing plants to Japan...or use to do it.
It is a major headache/ problem.
To ensure that no pathogens are imported to Japan every tiny bit of soil has to be washed off before the plants can even be packed.It is very time comsuming. Then there is all the paper work. Not many are prepared to do it.
To bring live plants into the UK is again extremely strict.
They have to be put into quarantine and inspected by the government people to make sure no horrible insects/diseases arrive on the plants.
In Britain Crug Farm are the only private nursery who have their own quarantine facilities.
I suspect that Botanic gardens world wide do not export the plants but exchange seeds which do not require such stringent conditions.
