I don't know about this. A tree trunk or branch covered with mosses, epiphytic ferns, orchids and general detritus would be an ideal place for all those thin black roots to wander. Whenever, I see those N. hamata roots popping out of half-dead LFS or climbing the condensation-soaked glass, I'm reminded of how cool it would be to have one growing epiphytically. I suspect that once established, it would grow like a weed.One might expect that it may grow slower or be smaller in general than if it were to have more room for its roots to expand.
Is that a young N. campanulata? I always thought that they couldn't grow well without limestone...
That is an absolutely gorgeous display piece. Great symetry.
Holy variegation batman! That may be the most impressive variegated Nepenthes I've ever seen.
