Question
Hi, i just wanted to know are there any species of neps, that dont become a climbing vine and if so what species?

Answer
Hi Dylan,

Just by nature of the genus all Nepenthes vine to some degree.  The ones that are slower about it would included plants like N. ampullaria, N. truncata, N. ventricosa, N. rajah to name a few.  You can also cut back a vine that begins to elongate making it produce side shoots to keep it more bushy and smaller.  I've done this many times with plants like N. sanguinea.

Good Growing!
