Oh yea,
they don't need a terrarium or anything...
I have a half dozen on a regular shelf in front of a window.
Thats why they are so popular.
Very easy to grow, and to root from a simple leaf cutting (with a bit stem attached).

They bloom regularly, with a rest in between.
Fertilize when they stop blooming, and cut back after they bloom a while...
gives them a rest, and bloom cycle.

And flowers do wilt when finished, and new ones replace them.

good luck!
