Allium triquetrum leaves are triangular in cross section also, because of the sharp ridge on the underside of the leaf. Allium ursinium (Ramsoms) is more common here in the wild than A. triquetrum. It is slowly working its way down the hill behind my house, especially now the country road edges and ditches are no longer maintained. Many of the more healthy eating families have a weekly delivery of seasonal vegetables. Ramsoms was included recently in Devon (SW England) as a bonus vegetable, complete with recipes to try.
