Looks like an Osteospermum. Take care when ordering - only one or two are perennial in this country, the rest are used for summer bedding.

I think its probably Osteospermum jucundum, which is hardy in the UK, unlike most of the other varieties.

Thanks to you both. I just googled that and it does seem to be Osteospermum jucundum. It does seem to come in alot of different colours, I did want the exact same colour as in the photo, so I will have to be careful when buying.
