Pulmonaria "Mrs. Moon," also known as Lungwort, is a member of the Borage family and is related to Virgina Bluebells, and the flowers are very similar.  Pulmonaria "Mrs. Moon" has attractive, slightly hairy spotted leaves and pink, turning to blue, clustered flowers.  It's one of the first plants to bloom in early spring, growing to almost 12 inches in dappled shade.  This gently spreading perennial makes a very attractive ground cover, as it readily increases in size, making clumps that are easily divided.  Zones 4-7.  Quarts.
