Amazing how much we learn from one another on 365 . I would never had known this plant which has appeared in my garden until the other day when @wendyfrost posted similar, and @shutterbug identified it as Green Alkanet , I was doing a bit of weeding , but for the moment this plant has been left to grow !
I know they are regarded as weeds but they have lovely blue flowers at this time of year. I see it often beside the road and it is a prolific self seeder.
A pretty shot with the delicate blue flowers and broad green leaves against your brick wall. Fav (I would give it a chance, Beryl, before you cut its life short- just see how it does. But then, I don't do the gardening :)
