This terrarium has survived multiple locations and many months in my house.
It doesn't make a mess and requires almost no care.
It cost about $12 and about 2 minutes to put together.
And it's a fake.
I normally think fake plants are a pretty bad idea, especially cheap ones.
(This fern was 99 cents at Michael's.)
But I've discovered that if you put them behind glass, or mix them with real plants,
or just display them at a distance, you can get away with it.
I added some real twigs from our backyard, some fake mossy rocks,
and behind glass I think it works.
So there it is--sometimes I'm a cheater.
