It has much narrower leaves than does Lungwort.

Stems still square with first pinkish-red flowers which may turn blue.

Leaves seem to be a lot more blotched with pale green than do the spots of Lungwort.

The specifications say that it has far fewer glandular hairs than does of Lungwort, but maybe this is a garden variety?


Some similarities to : Pulmonaria angustifolia [which seems to have no common name despite being a popular garden plant from Europe] also has long leaves, but the two are easily distinguished from one another, the latter lacks marks on the leaves.

Uniquely identifiable characteristics

Distinguishing Feature :

Just like Lungwort it contains poisonous Pyrrolizidine Alkaloids.

You are only likely to find it growing wild in Dorset, but does occur as a garden escape infrequently elsewhere.

The flowers of Lungworts are heterostylous, meaning that there are two flower types, the pin (aka longistylous) form and the thrum (aka brevistylous) form (no, flowers don't make humming noises). The two forms are sexually mutually exclusive - either form can only fertilise the opposite form - they are said to exhibit heteromorphic self-incompatibility. See Primrose for examples of pin and thrum forms.
