if its a ground hugging plant possibly Ajuga, if not and produces a pink flower probably one of the Silene. How long are the leaves?

Leaves don't look veined enough for Ajuga, although it is remarkably similar otherwise...

It's definitely not ajuga

It looks like Pittosporum tenuifolium 'Elizabeth'.

I have Silene dioicea 'Clifford Moore' that looks like this too but the pinky colouration isn't a feature of it.
the lack of obvious veination is why I said possibly Ajuga.
It doesn't look to be woody so that would rule out Pittosporum. Must say I like the look of Elizabeth.

has it flowered at all if all what was it like?
