See attached picture. Is this growth normal? If not, what do I do?
I think it is crown gall, a bacterial infection.
Probably your best course of action is to carefully remove the plant from where it is growing, before the disease spreads to some other, and possibly more valuable plants you may have.
Since crown gall is caused by is a soil borne bacterium, you might avoid planting anything in its place for a couple of years.
