Newbie with a cutting question

hey when you do a cutting on a nep ,will that nep still grow?newer leaves?(if the top is cut off then no new leave can form right?
The Nepenthes vine can create an all new plant from a section of stem only two leaves long. There is a dormant growth node (or meristem) inbetween each leaf. If you look closely just 1/2 or 1 cm above where the leaf attaches to the stem you will see either a nipple or a navel shaped structure or depression (depening upon species). This is the dormant node, which is there incase the plant should have it's growing tip decapitated the plant can simply regenerate from the next viable node down. Sometimes when a plant is cut the next two or three nodes become active and the plant becomes bushy.

Not all dormant nodes are viable. The older a vine is, the more "woody" it becomes and there is less chance of the nodes between the old leaves on the woody part of the stem sprouting.

hope this helps!
k thx so for every two leaves there will be 1 node?
The node is usually located 1/2 to 1 full centimeter above each leaf, look for the nipple or navel structure. On a tiny plant it will be near impossible to see but on a average cutting it should be visible.

What I meant by "between two leaves" is that a two leaf section are the minimum amount of plant material needed to start a relatively mature quick growing new plant from the dormant node. I have started a plant from simply a gouged out dormant node with no leaves or roots off from a N. Ventrata hybrid planted in pure living sphagnum and kept moist with intense light and high humidity but it took a very long time to establish and become a plant.
the node is really tiny right?is it the small green shoot?

1. A knob,knot, protuberance, or swelling.

There's an axillary bud at every node, so technically speaking you can make a cutting from just one node.

i made a cutting and there was black stuff on the insides of the stem of the "parent plant".Is this normal?
