My father-in-law bought for my wife, two years ago, a Nepenthes for Mother's Day. To the best of my knowledge, from leaf and pitcher comparisons, it appears to be N. ventrata, or possibly another cross of either or both parents. It was not id'd when he purchased it (at a farmer's market in Fla), not even to high or lowland. He was told it was "incredibly easy" to care for. He also bought one for himself at that time (since deceased) and picked up another for himself this year. Mine (or my wife's, but it's in my care) is still going very strong. So what's the problem? Well, I swear the thing is mocking me. Every day it taunts me with its lack of pitchers. Anyway, the thing's got about a dozen points of growth, 3 of which are actually rooted (one a cutting I took of a longish piece). The leaves are bright green, no crisping at all, no yellowing, nothing, except for the tendrils, which just won't produce a thing. Currently, it's being kept in a southern window that also gets eastern and some western sun. Lighting, I think, is probably not a problem, right? It WAS being kept open air in my home (40% humidity, controlled). I've since built a sort of enclosure out of a quilters gizmo, some round thing with an inner and outer ring that clamp together. The rings are now holding a dry cleaners standard plastic bag which hangs over the plant. I don't have a hygrometer to measure humidity currently, but a guess would be about 60%. It's been in this situation for about a month now. There's one new tip that looks like it might be promising, but I'm not holding my breath here. For reference, this quilter's ring thing is 18" in diameter, and the most mature leaves of the plant extend, while hanging, almost the full 18". Temp is roughly 72-74º during the day in the window, down to about 65º in the window at night. I've ordered thin but rigid film to make a more permanent enclosure. Is there anything else I can try? Or am I destined to have a "toothless" carnivore?
