The flowers of Pulmonaria come in various shades of pink, purple, and blue. There are also white ones (e.g. Sissinghurst White), and a true blue one (Blue Ensign) which has plain green, not variegated, leaves. I have even seen a scarlet red one. They self-seed and hybridise, so the white and blue may eventually change colour. But I don't mind, as they are all so pretty.
