Nepenthes ventricosa x truncata is a larger easy to grow plant. Both the leaf span and the pitchers get bigger than a lot of Nepenthes out there, N. truncata helps in this regard. This hybrid does just fine for me in the winter where it is a bit cooler than intermediate conditions and in the summer where it is a bit cooler than lowland, but if I were to chose which it likes more, I would probably say the warmer side but in both climates it grows and pitchers just fine!
Shipped potted in a 3.5" ready to grow!
Turns out I don't have a photo of a plant growing and pitchers other than when I did cuttings :-\ but you get the idea!
