I suppose I could keep it in it's pot. It might not look quite as neat, but I think it would still work.
I may forgo the jar idea and just get a nice orchid to place near a window and find another pretty flower that would enjoy an enclosed environment.
The woman on TV made it sound like this would work wonderfully and the orchid would thrive well in the jar, but I guess that's why they say you shouldn't believe everything you see on TV.
Thanks for the info!
