Note that Comma has been reported Inverness area. I have yet to see one here though (Nairn/Moray).

Interesting stuff, Guy.

When I was a kid, there were no Commas round me (Liverpool area) and much of the literature available had their LHP down as hop. I wonder whether this progressive preference towards stinging nettle is a contributory factor in their geographical range expansion over the last 25 years or so?
