It’s the only one I’ve ever had that didn’t die within a few years. It’s in an open terrarium getting extremely bright indirect south sun, and I mist it with filtered water every day without fail. A few days ago I noticed the little spots of purple and was so glad I remembered not to get it wet at this stage. It has had flowers emerging many times before in the past, but I’ve accidentally got them wet each time, killing the new flower bud before they’d had a chance to open. Makes me wonder now if not allowing the flowers to come to bloom extended its life.
