Has anyone grown a Nepenthes hybrid with particularly strong "hybrid vigor", either faster growing than the parents, or more tolerant of conditions outside the preferred range of the parents? I have noticed this trait in some hybrids, but not in others.
One example I can give from my own collection in my N. sibuyanensis x robcantleyi. This was one of the first Nepenthes. I got it mid-summer, when my conditions were firmly "lowland", days in the 90s, nights in the 70s. My conditions for the other 10 months of the year are 10-15 degrees cooler day and night. I grew it as a houseplant under lights, in 40-50% humidity. It acclimated easily, grew steadily and pitchered. It has since sped up and done even better now that I have cooler temps and a hydrofogger. I'm pretty sure these conditions would have killed either of the parent species.
