Tropicals & Tender Perennials: Epiphyllum seedlings, 1 by Studley

I couldn't take the wait any longer, plus I knocked off the seed pod while moving my epiphyllum. I was amazed to see that the seeds had germinated within the pod. I guess this makes sense for a plant which normally received little rainfall. I have potted up the seedlings now. I was just wanting to know more about epis. Will all of the seedlings be different? Different flower colors, etc? How common is it to get seeds from an epi? Has anyone got experience with growing them from seeds? How long does it take for them to flower? Here's a photo of the seed pod opened to show the germinated seedlings.
