Darlingtonias, in their natural range in Oregon, extend from the coast
to the mountains inland. In the Siskiyou mountain range, they can
receive snow, but their hoods tend to brown at cold temperatures. On
the coast, they seldom receive snow, but the temperature is in the 50
degree range in the summer, and cooler in the winter. They like to have
their toes wet, or moist, but do not submerge their roots. They live on
stream banks or bogs where there is cool water running. On the coast,
the soil they live in is sandy and swampy/boggy, almost marshy. In the
mountains, the soil is like most mountain soils, with chird or rocks,
but the Darlingtonia there tend to build up clumps where the soil is
spongy and a lot of dead dry grasses and detritus builds up. Areas with
dead logs, twigs, etc. Lots of decaying material covering the soil.
They always seem to grow in areas where water flows through, quickly or
slowly, and exits. So, the water tends to always be fresh. So, if you
have them in pots or something, the water should probably be refreshed
at intervals.

In the mountains, summer temperatures can get higher than on the coast.
So these things will survive extended periods of 80 degree weather in
the Summer. And, in the mountains, they don't have any shade or
protection from trees or other plants like they do on the coast. So they
can take full sun, as long as you don't have searing heat.
They bloom with purple/green/brown blooms in May.

If you want to know the yearly temperature range, contact the weather
service in Oregon (or whatever agency handles this) to get a listing
of the yearly coastal temperatures around Florence, and the yearly
mountain temperatures around Cave Junction and O'Brien.

These are the only areas I saw them in, so the information here is
probably incomplete when considering their entire range.
