Beaucarnea, or Nolina as it's sometimes called, is often known as the Pony Tail Palm.
The Beaucarnea has a swollen thick brown stem at its base that stores water. The long, narrow curly, dark green leaves flow up from this base much like a plume of water in a fountain.
This Beautiful specimen grows slowly. The plant will do ok in a slightly shady spot, however it does need bright light for success. If you can provide some sun you will see the plant producing lush new visible leaves, i.e. more light equals more growth.
