@rootsCommon names: germander speedwell, bird's-eye speedwell, cat's eyesLooking at the flower in the Wikipedia article, I'm not sure if it looks like any oind of eye, burd or cat!Cousin to thyme-leaved speedwell, which we saw a few hours ago (same genus, Veronica).My favourite fact from the Wikipedia article is that, although now considered a weed, this plant was so popular for making tea in 18th century Britain that it was almost eradicated in London!
