Senecio angel plant

I have one of these and it looks like an octopus.  I have 1 main stem 15 inches high with new growth at the top and about 12 arms coming of the main stem a 1/3 of the way up, all around 12 -15 inches long, bending in all directions with new growth at the tips.  I have taken off all the dead leaves, just wondering what I can do to improve the plant and maybe propagate new plants from it.  Any suggestions welcome
