I thought it was a dracaena too but I cant find any pictures that look like it. Keep in mind that my picture is after it lost all the leaves. It used to be covered in leaves all the way to the soil. The lower 1/2 lost all the leaves so now it looks like it has a large stem.
I've thought its possibly a Janet Craig Compacta as well so i would believe that. I just have not been able to find a picture that looks just like mine before it lost all the leaves so i havent been sure. Here is a really old picture of it when it was much younger to see if that helps. Can i expect the lower leaves to regrow if it is a D. JC?
