Common Lungwort / Plućnjak

Pulmonaria officinalis


It is an herbaceous evergreen perennial rhizomatous plant. The basal leaves are green, cordate, 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. The leaves of this host plant are eaten by the caterpillars of the moth Ethmia pusiella. In spring, the plant produces small bunches of flowers. The 5-petals flowers are red or pink at first, later turn to blue-purple during the anthesis, by changing the pH value inside of the petals. As a matter of fact the flowers contain a dye that belongs to the anthocyanins and change the color from red (acidic) to blue (alkaline). Pulmonaria officinalis is diploid and has the chromosome number 2n = 14. Flowering period extends from March through May and the seeds ripen from May to June.


It was used since the Middle Ages to treat coughs and diseases of the chest, perhaps for its hard hairiness (expectorant effect).So it has been cultivated for centuries as a medicinal herb, the ovate spotted leaves held to be representative of diseased lungs, following the Doctrine of Signatures. In fact it is useful in the treatment of chest diseases and asthma.

Hehe. It's certanly hard to photograph European butterflies-you think you got them, and then they fly away just like that! :D

Especially those crazy European butterflies, I honestly think that in Africa or Asia butterflies are calmer and more willing to let you take the photo!

Tell me about it! I see so many amazing animals around here, but in the end I wind up without camera or am too late to take the picture or the picture turnes out blurry! :)
