Lithodora diffusa after flowering/winter care

I think it depends how much space you want it to fill. If you cut it back a lot it will limit the flowers you get in spring. I just trim it if its covering something else.

The best tme to trim this back is immediately after flowering. The next year's flowers are carried on the new growth.

I hadn't realised the name had been changed . This is my old favourite Lithospermum Heavenly Blue. It was supposed to be hard to propagate. My Wife who did all the cutting taking, was always so pleased when she had a boxful all rooted. I have only just brought it back to my, garden,but haven't taken any cuttings .
