I've got some Nepenthes that are supposed to be able to handle out-of-terrarium conditions (N. alata x (ventricosa x alata) and N. sanguinea,) or so I was told by the guy who sold them to me. Right now I have them in a ten-gallon tank because I don't have any other plants that would like to be in said tank any more than the Neps.
However, some have started to climb (and be a general sprawling nuisance,) so I'm thinking about cloning. If I could evict a few of my Neps from the tank, I'd have plenty of space for clones. Also, I'd just like to have some Neps around the house, where they're more visible. So, I guess what I'm wondering is, what are your favorite "windowsill" Nepenthes varieties?
