My little jewel orchid was not thriving in the terrarium; I don’t think it had enough light. The moss I purchased was thriving though, so I went looking for something relatively tall (1-2 inches) to crown my miniature hill. I found Climacium Tree Moss (Dendroides / Americanum). This moss grows a kind of trunk and looks like a miniature copse of trees. Adorable and perfect.

The jewel orchid lost its roots (probably too wet in the terrarium), so I put it in a jar with some living moss near a north facing window (no direct sunlight, but plenty of indirect). I’ll post an update on it as it recovers. I’ve read that an orchid can regrow roots from healthy stem and leaf, so I’m hoping.
