Identify this plant!
 

hi,

i bought this plant the other day on a whim and I have no idea what plant it is and how to look after it. here is a link to a photo of my plant:

some of the leaves are going dry and brown at the ends, so i need to know how to look after the plant before it dies!

thanks in advance,
