Pinguicula longifolia ssp caussensis
Pinguicula longifolia is one of the most striking of the hardy Pinguiculas. This subspecies occurs
in the Alpes Maritimes in southern France. Plants I have seen were paler than P.longifolia ssp longifolia
with smaller flowers, but this was at the end of June, when the plants were coming to the end of their
flowering period and seasonal temperatures and sunlight were increasing rapidly, so plants were potentially
stressed and slightly bleached.
Mountain springs ensure that this rock face is continually moistened with a fine film of water running down it.
Though it looks like rock, the habitat is closer to being a low nutrient vertical bog.
