skylark said:i did not know the plant with blue flowers. so had to go search for it. the closest seems to be
Lithodora diffusa 'Heavenly Blue' (Purple gromwell 'Heavenly Blue'). is that what it is? the leaves are so-o similar to rosemary! and thyme and juniper next to it? very elegant!
Thank you skylark, and you are good at sleuthing! I can't research with just a picture; takes too long to make the right discovery and I would have a big headache by then. But you are correct that blue flowers are from Lithodora diffusa...but it is 'Grace Ward' and planted next to Thymus 'Doone Valley' (and also another, French Thyme) and an unknown juniper.
The blue on blue theme was happenstance. I chose the Lithodora solely for its ground cover-like growing pattern and its very dark green leaves to go with the lighter color leaves of the two thymes It was a surprise this Spring to see the blue flowers(!) appear which matched the blue pot very well. So I have to admit that the blue on blue was not planned...
