Spring Growth & Flowering (February-April)
6-8 weeksFoliage expands dramatically with distinctive white-spotted silver leaves. Flower buds emerge from the center, opening into pure white bell-shaped flowers in clusters.
Continue consistent watering. Divide overcrowded plants in early spring if desired. Remove old foliage from previous year before new growth.
Post-Flowering Foliage Development (May-June)
6-8 weeksFlowers fade and drop. Variegated foliage becomes the main ornamental feature, with leaves reaching full size and color intensity. Plant fills out with dense, mounding growth.
Deadhead spent flower stems if desired for neatness. Maintain consistent moisture as temperatures warm. Apply compost mulch.
Summer Rest (July-August)
6-10 weeksIn cooler zones, foliage remains vibrant and ornamental. In warmer zones (7-8), leaves may become less pristine if hot and dry; some dormancy may occur.
Maintain moisture, especially in afternoon heat. In warm climates, provide afternoon shade and extra mulch. Avoid overhead watering.
Fall & Winter Dormancy (September-January)
4-5 monthsFoliage persists but may fade or brown in harsh freezes. Plant dies back to the crown in cold climates.
Leave foliage intact for winter interest unless severely damaged. Do not prune until early spring. Mulch heavily in zones below 5 for winter protection.

Uses
Traditional herbal tea (historical use)
CulinaryPulmonaria was historically brewed into medicinal teas in medieval and folk medicine traditions, though modern culinary use is minimal. Leaves contain mucilage compounds traditionally believed supportive of respiratory health. [source]
Lung health traditional remedy
MedicinalThe common name 'lungwort' derives from the plant's historical use in European folk medicine for respiratory conditions, based on the appearance of spotted leaves resembling diseased lungs (Doctrine of Signatures). [source]
Pollinator support and bee forage
WildlifeEarly spring flowers provide crucial nectar and pollen for emerging bumblebees, solitary bees, and other pollinators when food sources are scarce. Flowers appear before most spring plants bloom. [source]
Woodland garden ornament & shade plant
HouseholdThe striking white-variegated foliage brightens dark shade areas year-round, making it invaluable for brightening woodland gardens, shaded borders, and near darker-leaved hostas. Provides continuous ornamental interest beyond the short flowering period. [source]
Fresh and dried flower arrangements
CraftDelicate white flowers can be used in spring floral arrangements, while the long-lived variegated leaves provide interesting foliage texture in both fresh and dried arrangements. [source]

Harvest Tips
Pulmonaria is a ornamental flowering perennial, not harvested in the traditional sense. Deadhead spent flowers in late spring for neatness and possible reflowering. Cut back old foliage in early spring (late February/early March) before new growth emerges. Divide clumps every 3-4 years in early spring or after flowering to rejuvenate and propagate.
Fun Facts
- 🌱 The name 'Sissinghurst White' honors the famous Sissinghurst Castle Garden in Kent, England, where this cultivar was selected and bred by renowned horticulturist Vita Sackville-West in the mid-20th century.
- 🌱 Pulmonaria flowers change color after pollination: the white flowers may develop subtle pink or blue tones after being visited by bees, serving as a visual signal to pollinators that nectar has been depleted.
- 🌱 The distinctive white-spotted silver leaves give rise to the common name 'soldiers and sailors' in some regions, referring to the white spots (soldiers) on the blue-green background (sailors) found in some red-flowered species of Pulmonaria.
