I just got some greenhouse space at work, so I've started to grow Nepenthes again after taking a break for the better part of the decade. A nursery I've gotten plants from before is offering two crosses I'm interested in growing, N. truncata x merrilliana "Caesar", and N. "thorellii" x (truncata x campanulata), but I'm concerned my conditions are not warm enough (Day: 75f, Night: 55f). I assume hybrids with the highland truncata would do fine for me, but I assume most N.truncata crosses involve to lowland form, since highland N. truncata has only become widespread in cultivation in recent years.
I've never grown N.truncata before, but I remember hearing that both the highland and lowland forms of N.truncata grow well over a very wide range of conditions. I have seen a number of examples of growers in cool climates growing lowland N. truncata alongside their highlanders (as well as growers in the tropics having success with highland forms). I likely can't get any sort of concrete answer on this, but I was wondering if N.truncata's tolerance for cooler conditions would be likely to be present in it's hybrids.
I remember a similar situation from back when I first grew Nepenthes. I lived in a climate with very hot summers and high night temps. The only highland nepenthes I had success with were N. ventricosa crosses, which tended to pass on tolerance to lowland conditions in hybrids with other highlanders.
