My first-ever terrarium (well, maybe not first ever, but the ones I attempted as a child didn't turn out remotely this successfully) is insane with growth. I have cut back the Pellionia pulchra, Fittonia, and Nautilocalyx pemphidius once each and shared some at a gesneriad society meeting. I need to do so again! Luckily, such a meeting is in only a week and a half.
The N. pemphidius has been flowering for weeks. I haven't tried to pollinate the flowers for some reason--they're inside a glass jar, I always forget to.
The ailing Pilea depressa I received in trade is rejuvinating in the terrarium--it's not quite thriving, but it's not dying either. Success!
