Alex - do you mean scientific cloning by taking a bit of plant tissue and using it to generate a new plant? Or do you mean reproducing the plant by roots or leaves rather than seeds? If it's the latter, a lot of succulents can be reproduced vegetatively. A lot are prone to producing offsets as a means of reproducing in addition to seed production. And, also, a lot are really more agreeable about replicating themselves that way than using seeds as a method of reproduction. Any specific plant you have in mind?
