An RHS AGM winner, Pulmonaria 'Blue Ensign' has clear blue flowers formed in clusters from March to May. Unlike many Lungwort cultivars, the green leaves of Pulmonaria 'Blue Ensign' don't have the typical pale spots and are broader and more refined, creating low spreading clumps that form useful but attractive ground cover. 'Blue Ensign' is perfect for bringing spring colour to woodland areas and shady borders where it will act as a magnet for pollinating insects. Height: 35cm (14). Spread: 45cm (18).
