Well no one said this was an easy species to grow in your climate. It may not be impossible, just difficult. And it may depend on the clone you have. One article in an early issue of the Carnivorous Plant Newsletter mentioned that Leo Song and others determined that this species had a maximum root temperature limit (I want to say 28C/82.4F). If the root temperature got above that the plants would die.
Availability from the West Coast nurseries is definitely cyclical. Two or three years ago these plants were as scarce as they are now. The next year there was plenty.
