Alan,
You can propagate carnivorous plants in many ways. Use can use leaf,
root and stem cuttings and seed. Plants such as Drosera can be propagated
by most of the above methods, while others such as the Nepenthes are best
by stem cuttings. They can also be propagated from seed, but this can be
a very slow process.
Propagating these plants is quite easy, as long as you use an open
medium, and ensure they that they have plenty of humidity. What plants
are you intending to propagate?
