Pulmonaria ‘Raspberry Splash’ is a small, spreading, semi-evergreen herbaceous perennial. Its dark green leaves are upright with rounded pale green/ silver spots, with entire leaf margins and are arranged in rosettes. Their upper surface is quite hairy. Its raspberry pink flowers are 5 petaled and lobed, with a tubular corolla, 5 stamens and are produced in small bunches on long stalks just above the foliage in spring. The fruit is a dry 1-4 seeded drupe or nutlet. The roots are rhizomes which aid the spread of this plant.

Pulmonaria ‘Raspberry Splash’, commonly known as Lungwort ‘Raspberry Splash’, is a cross between Pulmonaria ’Bertram Anderson’ and Pulmonaria ’Barfield Pink’. This variety is one of the more upright and more mildew resistant Pulmonaria.

The etymological root of the binomial name Pulmonaria is derived from the Latin pulmo ‘lungs’ in reference to its historic use.
