The origional purpose of the terrarium was to root cuttings of plants, which I could then take to the flea market to sell. These got stuck in there after I repotted them, and they got a little wilty. So I stuck them in the terrarium and treated them like cuttings. They promptly began blooming and they've been thriving ever since.
It breaks all the rules... They get water all over the leaves, (It's hard to water over a foot and a half tall piece of glass without splashing some) but they don't develop brown spots... I have no idea why. Maybe the higher humidity has something to do with it... someone suggested that the water on the leaves may be a problem because of it drying on the leaves, where the humidity in the case keeps it from drying. Sounds just as good as any other reason. I don't worry about it. It's working, so I ain't arguing about it.
This seems to be a semi-dwarf variety... the leaves are small, but not as small as a miniature, and it has lots of happy little grape colored flowers.
