The pot looks small for such a large shrub (by potential, not your particular specimen in its' current state.) And being black, it's going to get unnecessarily hot when the sun shines on it.
Your shrub looks like the seedy/weedy kind my Mom got that we decided to evict from her yard. There were a LOT of sprouts showing up. I would encourage you to seek a sterile cultivar to avoid that frustration.
