Even before the wedding planning began, I have always had a fascination with terrariums. I by no means have a green thumb, but it is fascinating to see a whole little eco-system growing in a pretty little glass bubble. 
These also remind me of the solarium that I hope to have off of my imaginary-future house. Jonathan and I have already made a deal that he would build me a solarium if he could build a treehouse for himself.
I think they would be great to put as centerpieces for the wedding, especially sitting on a freshly cut piece of sod with tealight candles surrounding them. I have yet to see anyone do this combination, but have found some ideas of the closest thing to them.
