Pulmonaria, common name Lungwort, is a semi-evergreen, early spring flowering hardy perennial.
Pulmonaria is a woodland plant which like semi shade with moist, well-drained soil. In these conditions, Pulmonaria will thrive and the plants naturally multiply. Because they flower early in the year, late winter/early spring Pulmonaria are attractive to emerging solitary bees, providing much needed early nectar in late February, March and April. Pulmonaria flowers are blue, white, pink and some a combination of both.
Pulmonaria are small plants, up to about 35cms and form clumps around 45cms, ideal for front of borders, ground cover or under-planting shrubs. Some varieties have attractive white spotted leaves such as in the image above and below left of P. 'Sissinghurst White' and also P.'Lewis Palmer', both of which have the RHS garden award of garden merit and P. 'Fruhlingshimmel'
Two of the strongest standout blue forms of Pulmonaria are 'Mawson's blue' and 'Blue Ensign', which is shown in the centre image, both of which have unspotted leaves.
Because Pulmonaria is a plant which likes moist conditions, it is not best suited to growing in container which tend to dry out more quickly that a garden border. If grown in a container, Pulmonaria would benefit from a mulch to help retain water, possibly some water retaining gel and the container would need to be placed in semi shade conditions.
