Yes to all of the above! These came from dropped seeds, but they're as easy as sedum to root cuttings from too! I did some of those at the same time I did the sedums. Easy peasy. Also rooted cuttings of sweet potato vine they are real easy and quick too. You don't even need rooting hormone. I just made a coffee cup of weak bleach/ water solution and dropped the cutting in there long enough to put planting mix in the pot. Worked like a charm!
I'm enjoying the visual in my head of purple petunias cascading over a creek wall. You don't happen to have a pix of that do you?
We eat our nasturtiums too. I forgot to plant my variegated leaved variety *gasp*, I can still do it! What's a few more things to water !?!
