Very nice! Mine isn't looking that happy. I think I let it dry out too much. Unless the plant I have has just reached the end of its lifespan (they are short lived, from what I gather). Either way, time to take some pullings!
I notice the very high water level in that bowl - how long has it been that way for? And is your plant happier because of it? Might have to give the 'nearly submerged' method a try.
Looks great. Every primuliflora I ever tried to grow has promptly expired.
I keep mine very wet never letting it dry out which I do believe to be the key to growing this ping well. I also feed it often.
