We've got an abundance of plants in our garden which we've been calling borage for 18 months.
Then I saw your photo and it was different to my plants.
Turns out we've got Green Alkanet/Evergreen Bugloss (pentaglottis sempervirens) which is part of the boraginaceae family.
It is in just about every border and verge and we're pulling it up as we go. Have read the taproot is huge and is a pain to get rid of. May have to resort to stronger measures.
Pretty flowers though.
