This is a real beauty. I bought it as a young plant from a supermarket, it has been in the ground 4 years at the conception of a new bed and grown with it. I planted it behind a pittosporum tenuifolium 'Tom Thumb', which has grown slowly with it, and the new growth always lays nicely over it, a great contrast. Not rampant, it doesn't need to be, with the right combination. Last year it started to make reasonable flowers, this year it has been spectacular! Many buds formed, flowering in succession for quite some time in early summer. It makes the occasional single flower later.

No pruning is necessary, easy, just plant and leave.
