Len, that c bulosa was grown submersed. Make sure the humidity is high if you're planning to grow it emersed. I had trouble with emersed growth. Good luck if you're going through that route and pelase share your experience good or bad.
Steve, this is the mother plant
- its a c bullosa alright.
Is that really C. bullosa? All the ones I've seen have bullated leaves. Maybe cause it's a young plant?
