Hi all, has anyone here ever tryed to propagate ZZ plants..

I read about it and heres my attempt at it, I read that it takes a year, is that right....I have one piece in water and the rest in soil....I found a branch broken at a green house and I asked if I could have it to try and grow, and they gave it to me, but said it probably wouldn't work. what do you think and any help is welcome....thank you ....linda............
