I'll check mine to see if it's large enough to divide. I don't think it is, but I'll look.
Edit: I actually bought this plant from Ratcliffe's..not that this helps at all. Anyway, my plant is now 2 blooming size growths. The growth that bloomed for me last year yellowed off. So, if you can't find anyone else that's selling them or has a bigger plant I could probably divide it if the roots are decent on both growths. I would have to empty the pot and double check the roots though, and I don't want to disturb it if you can find another source.
