    Sorry, I don't have any photos...I'll try to take one.

    I have a "new" clone coming, so it will be interesting to see how it compares.

    You may be right. However, I have three specimens of this species, all of which are unique, seed-grown plants. None of them have done well for me when overnight lows were much above 50 F. In my experience, for them to do really well, I need overnight lows of about 46 to 48 F. Furthermore, I have found the other species you mentioned (NN. macrophylla, hamata, etc.) to be much more forgiving of overwarm nights than N. aristolochioides.

    I guess you will find out when you have a chance to experiment with your new specimen. Please let us know how it goes.

    N. macrophylla is much more tolerant than many think.

    Does N. aristolochioides really need to be that cold Jeff? Boy, I've underestimated its highland heritage...I'm running around 80F in the day and down to 50-52F at night, reckon I should drop it lower?

    Are they growing well? If so, it's probably cold enough.
    But, as I mentioned, I found that under my conditions
    this species needed nights in the 40s.

    OK, I've not been growing aristolochioides for very long, but my plant is cheerfully making new pitchers at a min of 10-11c.
    Also, regarding macrophylla being tough, I've been growing a seedling under similar conditions to the aristo for just over as year now. Yes, it's trebled in size but it's still painfully slow....
    Cheers,
    T.

    I've found my aristolochioides more tolerant than Jeff's. Mine do really well with nights at or below 15C. They tolerate much warmer nights over summer, they just don't grow much at all. They've had days where temps have gotten over 40C, but it hasn't harmed them. However, in winter, when days are cool (25C or less in the greenhouse) and nights are cold 7 - 15C, they grow really, really rapidly, despite the much shorter daylight hours.

    It may depend on individuals. I have about 10 seedlings of this species, and they show a reasonable amount of variation in growth in the same conditions. How much is just strong versus weak individuals, reactions to growing conditions, or the potential for some of them to be hybrids, I don't know.
