Hi,
I grow several highland Nepenthes species and hybrids
outdoors in Santa Monica, CA, about a mile and a half
from the ocean. Winter low temperatures occasionally
dip as low as 5C, but average lows for winter months
are around 9C to 10C. (The official temperatures recorded
at the Santa Monica airport tend to be a bit warmer than
what I record at my home.)
Humidity is sub-optimal. In the winter and spring,
it is usually above 50% RH, but in the summer and fall,
it can get as low as 20%. I water the growing medium
with reverse osmosis water, but on dry warm days,
I mist the leaves two or three times with tap water.
The species that have grown well include N. khasiana,
N. ventricosa, N. alata (striped highland), N. sanguinea,
N. maxima.
Hybrids include N. 'Emmarene' (khasiana x ventricosa),
N. bongso x maxima, N. ventricosa x inermis, and
N. thorelii x (x wittei) [rather surprising that it
does so well in a cool climate, since it has lowland
parentage].
These have all grown into large plants and some have flowered.
Some grow slowly year-round, while others grow little in the
winter and then grow vigorously in the summer.
Now I'm trying several different N. ventricosa hybrids
from Andreas Wistuba. They are all small, but are growing
vigorously. I'll see how they do in the winter.
