Plant your Nepenthes in a hanging pot a.s.a.p upon receipt. Or use a tall planter that it can hang over the edges. The pot should have holes in the base and hopefully a matching saucer for drainage. You could also use a normal pot with holes, inside a larger planter without and catch the drain-off in there. Add a layer of hydro-pellets, then some fresh potting compost and plant your Nepenthes at the correct height for it to hang over the edge. Fill the pot with more potting compost and press the whole thing carefully in. Do leave sufficient space for watering between the top of the soil and the pot edge.
Water generously immediately and give your plant a nice warm spot (preferably), in part shade. No full sun and preferably not about a radiator. Avoid draughts as much as possible.
 

Water your Nepenthes regularly and do not allow it to dry out. Rain water is preferable. Carnivorous plants should not be fertilised at all. While this plant will tolerate low humidity, the Nepenthes may well develop brown edges to its leaves so you would do well to spray it regularly with rain water to avoid this. You could also try potting up to a larger external planter with a layer of hydro-pellets in the base. Stand the plant in its pot on the hydro-pellets and excess drainage will help keep the humidity up.
Your Nepenthes will create longer shoots after a while and you could then perhaps train these up a frame of some sort that's in the pot. If not trained upwards, it will definitely need a hanging pot, or a tall planter to allow it to trail.

The foliage is a lovely bright green. Each leaf develops the bright red, hanging chalice shaped flowers. The more light this plant gets, the redder they will be. Nepenthes originated in the tropical rainforests of Central and South America where it grows long lianas/vines. We can luckily grow these plants as houseplants so they are less vigorous.
