Too bad Elin, I have no idea whether Clorospatha will creep, clump or climb. It is new to mee too. As the pandemic strike last year ecuagenera been visiting our country, and that made it possible for us to get these. But again they came with little or no information. Judging from their fleshy rhizome they are a creeper not a climber, but mine is still a very small plant. Plants can surprise you.., When I get a Rhodospatha few years ago I was sure it was a clump forming plants until it gets happy and start climbing.. If Chlorospatha becoming a climber I would'nt be too surprise.
Hearing you mention it is a bog plant made me thinking to try propagating mine when it get slightly bigger, and experimenting, perhaps growing one in more wet situation.
