I root mine in water also. Actually, I root most stuff in water lately. The only things I think probably won't make it are the bunch of cuttings I took from leonotis leonurus alba / White Lion's Tail. The plant was large and in a falling apart half barrel that I wanted put of the way. Since I have another Leo Alba, I wasn't too worried about losing it and didn't want to bother with perlite cuttings, so just took a lot of cuttings and have them in water now. I don't expect them to make it, but it was a good chance to find out...lol...and with that number of cuttings, perhjaps one opr two may make it. It has a woody stem.....
