Lithops sp.

Lithops sp. are native to the arid regions of southern Africa.  This plant has very low water requirements.

Lithops, also known as "living stones", are small, succulent plants that resemble stones or pebbles.  They are dwarf plants with two thick, fleshy leaves that fuse together at the soil level.  The leaves have a window-life shape that allows light to enter the plant.  Leaves come in a variety of patterns and colours, including tan, olive, orange and occasionally blues.  

A great starter plant as long as you are capable of just ignoring it.
