Clusters of purplish-blue flowers hang from the greenery of ground ivy. It's growing close to the foundation of the house and I am stunned by the beauty of these tiny flowers and with the square stem. Were you aware that some plants have square stems? It is a member of the mint family and considered an aromatic herb, although it does not smell 'minty'. It has been called ale hoof and was used as a seasoning in the brewing of ale in Germany. Gill-Over-The-Ground is the french name for this plant, gill meaning fermented ale in french. I think that stripped of their greenery they could masquerade as orchids.
