Hi List,

Sorry about that blank letter... Anyway, Pinguicula DOES NOT
grow in peat or peatmoss. All soils should contain at least 70%
material(s) other than peatmoss, sand is often the best option.
Some Butterwurts (my German take on the name) can't tolerate pure
peat moss at all and the roots and leaves die on prolonged
contact with it. Believe, I've killed far too many, but now I
know better. Often they can be found growing on bare rock or
as epiphytes so it appears they like their roots to have lots of
air flow which peatmoss cuts off.
