Adenium (Desert rose)
You probably do not consider this to be a bush, but if you allow it to grow, it will become more than 2m high and across. It is then extremely straggly, so it is usually kept cut back in to a small plant. It is not all that hardy in the summer sun (although it is a native), and is best moved in to the shade.
The flowers are mainly red/ pink/ white colours and it should flower frequently during the year.
