Definitely not Hibiscus - looks more like an Azalea.

Thanks Bamboo-- shows how much I know!

Not sure it is Azalea though!

my first thought was azalea too. has flower buds so we will know come the autumn.

Thanks everyone for help!

Autumn? don't you mean spring, Seaburngirl...

I thought it was an Escallonia ...

Going by pictures, Escallonia seems more likely.

I did mean spring. oops
my escallonia has different foliage to this.
