Can anyone name this plant?

Maybe a Boltonia asteroides?

Hi, could be Cranbe cordifolia, Derek.

Could it be a aster!

Hi,it could be Aster umbellatus, Derek.

Or even Aster ericoides!

So, no, we can't!

Hmm...Crambe cordifolius is a member of the mustard family, and the blooms are more like arugala than daisies. Aster Umbellatus is a definite candidate, but the ones that I have seen have fewer rays than these are showing, and a more upright habit. Aster ericoides, on the other hand, has a more prostrate habit than these, from what I have seen. I still stand by my suggestion--though I could easily be wrong, too! :)

Aster ericoides White Heather grows to about 4 feet so not particularly prostrate.

Ah, the ones I was looking at must have been shorter cultivars. Oddly, one of the shortest that I saw was labelled 'White Heather', but I know how labels often go!

Thank You for the Nice Replies to my Question about the plant :o)

You're welcome, Ladyessex! :)

You don't say when the picture was taken but it looks like it could be Osmanthus burkwoodii or Olearia hastii. These are both evergreen & spring to early summer flowering.
