In reply to Sean Kelly:
Out of interest I checked the altitude range for wood anemone at
http://bsbi.org/altitudes
Anemone nemorosa 1190m Ben Lawers
(I think my 'record' would have been more like 950m when I worked on Ben Lawers but don't have my field notes to hand)
so, at least in Scotland, it grows at altitudes higher than Cloggy
