I purchased some seed last year from a very reputable seed merchant
that I have grown on, beleiving that it was Meadow Cranesbill.

I have since planted lots of plugs out into my fields.

The problem now comes, that I have kept some plugs in my greenhouse,
for seed collection.

Only to find that the flowers are white ??? They are not White Campion
as they do not have the bladder behind the flower.

I have tried scouring the internet to see if White Cranesbill is a
native or not, any help please.
