Wild/Perennial/Babington leeks

Hi again - I know absolutely nothing about Phytosanitary certificates. The Government website has this https://www.gov.uk/guidance/export-plant...eland#fees which implies that there is a cost attached to the inspection and certification of plant material.
I've heard about several companies that have stopped selling seeds/plants outside the UK because of the complexity. Since the UK left the EU it has become very restrictive as we can't even send seeds to the EU now.
Can I ask why you're so interested in Babington leeks?

Most of my family is from Ireland and Scotland.  I've only been over there once, but I was quite taken with the Irish country side.  I just happened to read about the Babington Leeks and was interested in trying to get some established over here in the mulched rows between my fruit trees.  I think I can accommodate their soil and climate requirements and would really like to try to get them naturalized on my farm. 

Alliums are among the very few things I can grow outside of a fenced area.  Our part of the world is overrun with whitetail deer, and they will eat just about anything. They have even taken to eating my the leaves off of my rhubarb plants (which, until recently, survived in the rows of my orchard).  

We have Allium tricoccum, a very close cousin of your ramson, over here.  I am propagating it, but would also like to get some of the Ramsons growing too.   Any interest in Paw Paws (Asimina triloba) or Persimmons (Diospyros virginiana)?  Interested in trading some?
