Pulmonaria longifolio "Bertram Anderson"
Pulmonaria or Lungworts are valuable plants, not only for their early pink or blue flowers, but also for their foliage. The clusters of nodding flowers, which attract bees, stand out well against the glossy green leaves. Plants make good trouble-free ground cover for moist shade; they spread slowly and need little care. The Latin root pulmo, gives this plant it's common name, lungwort. The Doctrine of Signatures describes Pulmonaria as an effective remedy for diseases of the lung because the spotted leaves carried on most species were supposed to resemble diseased lungs.
"Blue Ensign" is one of the earliest varieties to flower, creating a good display of bright, blue blooms throughout March and April. These fade gradually to purple with age. This variety is distinctive because it has plain green foliage.
