In San Francisco, which is much more moderate from the influence of the
Pacific and its famous fog, and less affected by the Sacramento Valley than
Antioch, we grow some Nepenthes outside. Geoff Wong has had a large N. maxima
outside for a couple of years now, its huge, but it doesn't have very many
pitchers. This year we had a low temp of about 30 deg. F ( about -1 deg.C. )
and there was no damage to that maxima or to my khasiana or the khasiana x
alata that I have outside, as one would expect. Nor did Geoff loose his other
highland species that were outside; N khasiana, carunculata, spathulata,
tentaculata and ventricosa. Some seedling villosas and raja's bit it though.
Judith Finn found that at the U.C. Botanical Garden on the hills above
Berkeley the 20 deg. F. (about -6 deg. C.) temperatures in December killed a
number of CP including a N. ventricosa that at first was thought to have
survived. I think that in the more severe climate of Antioch ( farther East )
any Nepenthes had better be under cover, if not in a climate-controlled
environment. This ain't Kansas, but it aint Borneo either.
Good Luck ( on St Paddy's Day )
and Cheers,
