This plant came straight out of Beetle Juice.

This is one of the easiest succulents I have ever cared for. My most neglected plant of all time and still chugging along. 

Care:

Light: Succulents need as much light as you can give them. In the winter a south facing window is best. During the rest of the year they'll be happy in any area that gets bright but indirect light.

Water: Succulents store water in their leaves making these plants very hard to underwater. However they can be easy to over water. Wait until the soil is completely dry before watering then give them a good soak. I like to wait till the leaves look a little wrinkled.

Temps: best kept between 55 and 85 degrees.
