Actually this plant is on my amazing to propagate list. As Pohdaddy and Greene say it is easy to propagate from a stem or leaf for an immediate plant, but more interesting is to take all the leaflets from that stem and insert their tips in a shallow pot of well drained soil. Forget all about it except to occasionally water, and first thing you know you have a pot full of hidden tubers which will eventually produce a really full pot of ZZs. I now have this plant in pots everywhere to donate to society plant sales.
