Care
Watering
Water regularly during the growing season to keep the soil slightly moist. Reduce watering after flowering. Avoid standing water which promotes root rot. In winter, minimal watering is sufficient.
Light exposure
Pulmonaria longifolia prefers partial shade or dappled shade. It tolerates a few hours of soft morning sun. In warm regions, light shade is preferable to prevent leaf scorch.
Soil and planting
Plant in soil rich in organic matter, well-structured and well-draining. Adding mature compost at planting time encourages establishment. This species appreciates humus-rich environments, as found in natural woodland.
Pruning and maintenance
Remove damaged or dried leaves after winter. Light tidying after flowering helps maintain a compact shape. No drastic pruning necessary.
Fertilizing
An application of balanced fertilizer in spring is sufficient. Favor light organic fertilizer if soil is poor. Avoid excess nitrogen which would promote foliage at the expense of flowering.
Diseases and pests
Pulmonaria longifolia is generally robust. Watch for powdery mildew in warm, humid weather (ensure good air circulation). Excess moisture can promote leaf spots; if infection occurs, remove affected leaves and improve air circulation.
Did you know?
The name "Pulmonaria" comes from the Latin "pulmo" (lung), because the white-spotted foliage resembles lung lobes. In the Middle Ages, people believed it was beneficial for respiratory complaints, according to the "theory of signatures." Today, this plant is prized by gardeners for its early flowering which brightens winter woodlands.
Where to buy it
Plant in spring or early autumn, avoiding spells of intense heat. Pick a plant with healthy foliage and roots that are not exposed. Best time: March, April, May, September.
