Identification: help identify plant from walmart

I purchased two of these plants at Walmart and have no idea what kind of plant it is. The container just reads 6" tropical. I want to get it healthy and happy, but I have no idea what it is or how to take care of it at this point. Any help?

 

it is a Lemon Lime Dracaena .. here is some info on it ..
