doesn't it smell like rosemary? if yes then that is what it is. I'm using a very small tablet and cant get a particularly good view of it. ;o)

or it could be lithodora that has bright blue flowers in spring.

Doesn’t smell like rosemary, looked up Lithodora and it does look like that. Thank you for that. :)

It reminds me of Phlox subulata. Lithodora leaves are rather thick and leathery …

I also thought phlox at first but the bright blue flowers made me think lithodora.
hopefully it will flower next spring and Amsterdam will let us know.

Ah yes, just read about the flowers lol ! :D Lithodora then …
Must slow down a bit .

Have just planted it in my rockery so hope it will give me a good show of bright blue flowers next year.
