Unless there is some supporting evidence for this to be Convallaria majalis var. montana
, I'd suggest it's the usual and very common European Convallaria majalis
instead, and that the photo should be moved to that entry.
The most noticeable feature that distinguishes Convallaria majalis var. montana
from the very commonly-grown Convallaria majalis
is that the midribs on the flower tepals are green (unlike on Convallaria majalis
which shows pure white) - your plant doesn't appear to show the characteristic green-striped flowers.
If you take a look at the comment posted for this entry, you'll see what makes Convallaria majalis var. montana
different from the Convallaria majalis
that we all grow. (And I'm not meaning to single out your photo particularly - the majority of the other photos posted under Convallaria majalis var. montana
are probably actually just Convallaria majalis
also.) Please let me know if you disagree.
