You plant them just like any other stem plant, and propagate the same way. They'll grow roots even if you just cut the tops off and plant them. If they are super short, just get enough in the substrate to hold them.
Growth rate is heavily dependent on light, CO2, and ferts. It's not a super fast grower though. One nice thing is that if you cut the tops off, I think they don't look funny/ugly like a lot of stem plants do.
