Pulmonaria officinalisis a herbaceous rhizomatous evergreen or semi-evergreen, perennial plant of the genus Pulmonaria, belonging to the family Boraginaceae. It was originally from Europe. Pulmonaria officinalisis grows to 30cm tall by 30cm wide at a fast rate.
The plant was given its common name ‘Lungwort’ during the Middle Ages. It was believed that the plant had a medicinal value because the lung-shaped leaves with its grey spots looked like a diseased lung, and therefore was considered an effective herb to treat lung-related ailments in humans. It is still in use today as a herbal remedy for several medical conditions.
The plant's basal leaves are green, with a rounded base, more or less elongated and pointed and always with rounded and often sharply defined white or pale green patches. The upper surface of the leaves has tiny bumps and it is quite hairy.
In late winter or early spring, the plant produces small bunches of terminal clusters of funnel-shaped hermaphrodite flowers. The 5-petals flowers are first white, red or pink later turning to a blue-purple. This occurs because the pH value changes inside the petals. This colour change occurs because the flowers contain a dye that belongs to the anthocyanins which change colour from red (acidic) to blue (alkaline).
Pollination is by flies, ants, bees and butterflies.
