Interesting topic really enjoyed reading thru the posts. I have two terrariums both empty now. The one is a very large round glass jar I have had from the 70's the other a small long GH looking thing that I have never gotten around to planting. For me I think the problem is displaying them. They kind of get lost in all the big house plants I have or crowded among the smaller philo on a table. I have the bug to get one going again, I have been looking at them on Pinterest, plus the Flower Show I was at last week and the Fairy Garden Workshop our Garden Club had the week before.
