looks like Teuchrium to me but which one not idea really. I have one but no species/varietal name as I got it from an open garden sales table.

I was thinking some kind of Veronica, myself. A close up of the flowers would help decide.

Hi Sbg, thank you for that, and the name does ring a bell..
I do quite like the spires of flowers, but not particularly the leaf..thanks again..

Yep, Sbg is right! Teucrium hircanicum. I learn something new every day...I just wish that I could retain more of it! :)

Great, thank you Tug for verifying it. I shall write it down now, so I don't forget again...
