I was thinking it looked like that plant, but it's not one I know well, only had for about a year. I hate to not have anything positive to say but the cuttings don't look good, browning at the bottom. When I've done cuttings of it, I let them dry overnight, then stuck in pot. Worked well. For future reference, any kind of fertilizer is said to be too strong for unrooted cuttings until they show signs of new growth.
Hopefully someone with more experience propagating this plant will have some advice for you.
