Polygala calcarea
Polygala calcarea, the chalk milkwort, is a species of flowering plant in the family Polygalaceae, native to western Europe. It is a delicate mat-forming evergreen perennial growing to 5 cm (2 in) tall by 20 cm (8 in) broad, with spikes of small, vivid deep blue flowers in spring, and leathery, oval leaves.[1] The white anthers of the flowers may possibly be the source of the name milkwort.
