Nepenthes 'Ile de France' is an old cultivar registered back in 2000 and is from the hybrid (mirabilis x thorelii) x (northiana x manxima). I'm not sure what happened to this plant over the years but you sure don't see it very much, which is a shame because I love the way it looks!
It is said to prefer warm to hot temperatures, but my greenhouse is only warmed to around 50f at night in the winter (and warms to 60s to 80s depending on the day for the day high) and it continues to grow and pitcher just fine for me. Not sure if it could handle these lower temperatures for a long time though (our winters are short).
