If you are saving seed, make sure they are not originally Hybrid plants... If you are using Heirloom Habanero, then, if you keep them from other peppers, these should grow true to your original. A good way to save seeds of all the heirlooms, is to lay them out on TP ( especially the wet seeds, like tomatoes) and when they dry to it, then all you do is tear off the seed with the tp, and plant the whole thing.it will grow fine.
I root my tomato branches that have broken off, in a glass of water, they root well..and are easy to transplant. I do know that pepper plants, like a tomato plant, can be planted deep and they will grow roots on the stem you have planted, which makes them stronger.
One more thing, if you're not sure if they cross pollinated, then by all means, plant the seed and see what you get. You might be surprised in the goodies that will pop out of it!
