We bought this yesterday put it (them actually since there are 2) in the ground today. Not quite a record but pretty good.
It also goes under the name Trailing African Daisy and the technical term is Osteospermum.
The light was pretty bad and doesn't really do them justice. They are bright white with blue centers and the underside of the petals are blue gray.
Update: I thought it could look better so here is a close up.
