Pulmonaria saccharata, the Bethlehem lungwort[1] or Bethlehem sage, is a species of flowering plant in the family Boraginaceae, native to France and Italy. It is a rhizomatous herbaceous perennial which is closely related to the common lungwort (Pulmonaria officinalis). Growing to 10 cm (4 in) tall by 60 cm (24 in) wide, it has lance-shaped leaves with white confluent spots, and pink or white flowers in spring.[2]
The specific epithet saccharata means sugared, and refers to the spotted surface of the leaves.[3]
