Identifying an unexpected shrub?
The attached image is an unplanned addition and I am having trouble identifying it if someone could help please?
Seems to have come in a Brunnera pot from a plantery, planted mid Spring this year - this is it's first summer and it has started really taking off, sending runners out, etc., so I am interested in whether I need t keep it, move it, or remove it completely.
It has beautiful leaves, no flowers so far but if I am keeping it, I'd like to be sure it's in the right lace of course!
In advance, thank you!
