I'm sorry - can't help you with the name - but its lovely!
Several of my cyms are box store noids - doesnt make them any less beautiful
Yes - when mine need to be potted up I go to the gallon nursery pots. So far I haven't need larger than that lol
I'm glad you decided to try out some cyms - they're pretty hardy plants for the most part. I have only killed one - that was from neglect - the interesting thing is all of my cyms were neglected just as much and didn't die!
Good luck with your cyms - and come join the group if you are interested!
