I have one growing outside. It is in the 4" plastic pot it came in with a chunky bark mix. I have it outside where it gets sun until about noon, then the area is bright the rest of the day. It is doing very well. It is also very hot and humid here. Temps have been in the mid 90's and humidity about 60%.
As it is outside in the heat, I water it about every other day.
I have not had it through a winter, but it seems a sturdy plant I bought it for the leaves and "structure" as I thought it was pretty, but the blooms have lasted for quite some time.
