Early-spring woodland plant known for flowers that change colour; a nectar source for bumblebees and early bees, with a small contribution for honey bees.
Lungwort is a low perennial of the deciduous woods of Central Europe, scrub edges and damp, humus-rich soils. The flowers open pink and turn blue as they age; the nectar is found mainly in the young, pink flowers. The corolla tube is fairly long, so bumblebee queens and long-tongued solitary bees benefit most. Honey bees visit on mild days, but their contribution is small.
Between March and May it stays in flower for 4-6 weeks, before the trees come into leaf.
There is no monofloral honey; the nectar is used up in spring build-up.
It is a bee-friendly early plant suited to shady corners of the garden. For honey bees, the willow, cornelian cherry and fruit trees that flower at the same time are far more important; lungwort only supplements them.
