Hihi!
Today I figured I'd finally get around to doing a glass jar self-contained terrarium. As you can see, I've used a red-leafed Acer Palmatum which is commonly referred to as a Japanese Maple. Unfortunately even in its juvenile stage it's a little too big for the jar, I also worry that this species does not make for an excellent indoor plant. Nevertheless we'll see how it goes! I've actually got about ten of these babies potted up which I'd like to put in my garden. I've got my eye on one in particular that I'll be turning into a bonsai once it's bigger too.
I'll see if I can get a better picture once all the moisture has gone from the glass.
