As tiny plants go, this one is likely easier than most. It doesn't need particularly great humidity (my plants put up with whatever they get outside), overwatering is likely to be more deadly than lack of moisture. And pretty much any temperature from about 35 deg F (2-3 deg C) to 100 deg F (38 deg C) is fine.
If anybody gets a seed capsule... I have read that the pods contain vanillin, can be cured like vanilla beans. Haven't tried this myself though...
