Through a bit of browsing on Melane's sugestion I came
across a list of plants which require a Plant Passport
for export out of UK. I was quite suprised at how many
of the favorite pfaf plants were included there.
This information has been taken from DEFRA Guide to Plant Passporting.
Which places restrictions on plants which can be exported from the
UK mainly because they are carriers for pests and diseases.
