I've always found citrus trees fascinating (of course, living in Wisconsin, we can't grow anything like that here.) I recently learned that you can buy dwarf lemon and lime trees to grow indoors!
I had to have one, and the local garden center carried them.

And bonus, it has two lemons already growing on it!
For anyone who is interested, the cultivar name is 'Meyer Improved'.
