I didn't have any difficulty with them. And once you get them going, they can be propagated from cuttings fairly easily. I forgot to take cuttings last year, so I'm back to starting seeds. Hmmm, should probably make sure I still have some.....
edited to add: whew! Thought for a moment I didn't have any seeds left! Anyway, it does mention on the seed pack I have to plant the seeds 1/2 inch deep and on edge. And they want temperatures from 68-72 to germinate. I had better luck with the purple ones than the white, BTW.
