Leaf shape can range from elliptic to a long narrow lance. Flowers are funnel-shaped, ranging from narrow to flaring, in relaxed forked cymes at the end of the stems. Flower color can be violet, blue, red, salmon and sometimes white. The color the flowers open with are only part of a description. Many have buds one color, opening to a second, then fading as they age to give the appearance of a third color - all on the same plant.
Colors are usually soft and muted making statements of quiet beauty.
If, when in bloom, lungworts look vaguely familiar that is probably because you already have a relative in your perennial garden. All relatives mentioned make fine companion plants. Pulmonaria enjoy some shade, preferably protected from the afternoon sun, and in the company of shrubs and deep-rooted deciduous trees. My lungworts are planted among deciduous azaleas and dogwoods. Before planting I work the soil to a depth of eight to twelve inches, adding large amounts of organic matter.
