My windowsill growlist (before purchasing my greenhouses)
Highland:
x Ventrata
alata
ventricosa
sanguinea
macfarlanei
ephippiata
burbidgeae
macrophylla (with great difficulty, not a beginner's plant)
maxima
Lowland:
bicalcarata (NOT HAPPY)
truncata (pitchered, but grew slower)
rafflesiana (happy)
For macfarlanei, ephippiata, burbidgeae, and macophylla, be prepared to get night drops in to the 50s, with a LOT of misting.
Bical needs misting too, but warmer temps.
X Ventrata, alata, ventricosa, sanguinea, truncata, maxima, and rafflesiana should be fine without any major pampering.
Hope i helped!
