beaucarnea recurvata 
'Nolina Ponytail Plant'
 
This big beauty will do best in a moderate light spot although can withstand living in a shadier spot too. The hardy stem is a water-holding capsule, meaning you can go long periods in between waterings. Keep them away from radiators as these plants do not like dry-air conditions. They are very hardy so they survive in colder temperatures, although not outdoors.
