I LOVE succulents.  They are pretty low maintenance, and come in all sorts of different colors and shapes.  Unfortunately my first go around with them turned out very poorly and I ended up killing all of them.  I watered them too much and put a few in direct sunlight and fried them.  Since then I research the different species I buy to make sure I am taking care of them correctly.   If you have ever had any succulents then you know that they tend to drop leaves.  You can use these dropped leaves to grow more plants.
