Question
I'm interested in growing a N. ephippiata, but I'm unsure of whether the conditions in my house are sufficient for it to grow decently. I don't have any space for a terrarium, so that's not an option for me. I would be growing it by an east or south facing window, so hopefully light is not an issue here (except for in the winter). The problem is the humidity; I'm under the impression that this species prefers higher humidity to thrive and I'm not sure how I can keep the humidity up without a terrarium. The humidity is around 40% here in the summer. In the winter it's a little drier, but not extremely dry. Would this plant be able to grow with lower humidity? Another problem is how to achieve a cooler night time temperature. There isn't really any place in the house that's as low as 10-15 C in the summer. But I have read different things about this plant. Some say it's easy to grow and others had difficulty with it, so I am stumped as to whether I would be able to grow it or not.

Answer
Hi Clarice,

Nepenthe ephippiata grows very slowly.  I think it took me about a year before my plant produced a pitcher for me.  And I grew it in my greenhouse!  I haven't seen this plant adapt to household conditions.  

Given your growing conditions, you're better off with the following:
Nepenthes truncata
Nepenthes sanguinea
Nepenthes ventricosa
Nepenthes alata
Nepenthes ramispina
Nepenthes x 'Miranda'

These plants grow very well in lower humidity.  Watch our May and June video podcast for an example of how these plants adapt to the home:

Good growing!
