Need to identify my new plant?

Question

I need help identifying a plant. To me it looks quite similar to a Yucca, someone also told me it looked like a Corn Plant. I'm not certain it is either though. It has a rough stalk like a Yucca, but it is not thick. Maybe about the size of a thick Hi-Lighter. It's about 4 feet tall. It had dark green leaves with a white border around the almost edge (green, thin white, 1/2 centimeter green to the edge). the leaves go almost all the way to the bottom. Maybe 1/2 foot of stalk with no leaves. My mom bought me the plant at a second hand store.

Answer 1

I think it might be a Dracaena.  There are different varieties.

Here are some pics...

Answer 2

I have never seen a yucca house plant, that was variegated if  it is a hybrid. A corn plant, is a Dracaena. fragrans 'Massangeana'
