Looks like Dracaena fragrans 'Warneckii'

That does look like a couple of the pics of the Dracaena Fragrans 'Warneckii" on Google Search . Thanks so much for the id !!! Now I can find out how best to grow it .

That's what it is. It's a terrific houseplant!!! Let it dry somewhat between waterings, don't keep constantly moist. Provide some bright light but not direct sun. They are EASY, genus Dracaena make terrific indoor plants.

the grower did a sublime job.. growing a small plant into a monster.. unfortunately.. he didnt up pot before sending it to market ..

let it get over shipping stresses.. being at the store stress.. and moving to your house stress.. and repot it in mid to late spring... perhaps when you are thinking of moving it outside for summer.. if thats an option ... put it in full bright shade for the summer ...

choice of media will be more important than anything else.. and go only one pot size up ..

I think when a lot of people buy indoor plants, the first thing they do is pot them into a bigger pot. But, the grower has been growing them fast, and maybe if they were still with the grower in his wonderful glasshouse or whatever, potting on might be an idea. But now, with the new owner, they won't be growing so fast. So they might be in too big a pot if they are potted on.

In this size pot (which your plant is currently in) there is less danger of over-watering. You can wet the entire rootball (and should), allow to drain, then not water again until you deem it necessary. That is trial and error. I don't agree with the phrase, 'let the plant dry out between waterings' because that would mean: the soil becomes dry (and probably water-resistant) (hard to re-wet).

That might seem to be an extreme of what is meant by 'let the soil dry out between waterings' but what is someone to think by that phrase?

Be guided by your own feelings on when to water. If you get the feeling that the plant needs water, water it well. If you are not sure, pick up the pot. How heavy does it feel?
