Pulmonaria 'Blue Ensign' is a cultivar of Pulmonaria in the family Boraginaceae, notable as a clump-forming 

 that flowers in spring. It produces short, mostly unbranched flowering stems arising from a basal rosette of leaves. The genus typically bears hairs on stems and leaves and spreads slowly by a creeping rhizome. Expect blooms from March to May.

Pulmonaria 'Blue Ensign' sits within the Boraginaceae and follows the general growth habits of its genus: perennial, clump-forming plants that regenerate from a slowly creeping rhizome. Flowering is an early-season event, with blooms appearing between March and May on short, usually unbranched stems. The leaves form a basal rosette and the aerial parts are often covered in hairs of varying length. Use these structural traits to plan planting positions: the plant's modest height and capacity to spread to about 0.6 m make it suitable for the front of borders or to fill gaps in mixed beds where an early display is wanted. Establishment comes from the rhizome, so allow space for gradual spreading rather than expecting a single tight mound. Maintenance focuses on monitoring the clump and dividing if the centre begins to thin, which renews vigour without disturbing flowering stems. For garden interest, the timing of Pulmonaria 'Blue Ensign' is its chief asset — it brings foliage-led structure and then a concentrated period of bloom in spring. Flowers from March to May emerge on the short stems above the basal leaves, giving a predictable seasonal marker in the perennial border.
