Dormancy/Winter
November-FebruaryPlant dies back to ground level in fall; foliage dies after frost; roots remain viable underground
No active care needed; leave dead foliage in place for winter protection or cut back in late fall; do not disturb dormant crown
Spring Growth & Flowering
March-May (zone-dependent)New foliage emerges in early spring with characteristic silver spots; flower stems appear simultaneously, producing pink buds that open to blue or bi-colored blooms
Maintain consistent moisture; apply balanced fertilizer in early spring; deadhead spent flowers to extend bloom and improve appearance; watch for powdery mildew in humid conditions
Foliage Development
May-JulyAfter flowering concludes, plant focuses on leaf expansion; mature leaves show prominent silvery-white spotting and variegation; plant reaches full bushy mound form
Continue regular watering; remove any diseased or damaged leaves; foliage becomes the main ornamental feature; some afternoon wilting is normal in heat
Summer Dormancy
July-SeptemberGrowth slows or stops during hot months; foliage may decline in appearance if conditions are too warm or dry; plant essentially rests
Reduce watering frequency but maintain some moisture; provide afternoon shade and mulch to keep roots cool; avoid fertilizing; this is normal and not a sign of stress
Fall Senescence
September-NovemberLeaves gradually yellow and brown as plant prepares for dormancy; foliage dies back completely after frost
Taper watering as growth ceases; do not fertilize; allow natural die-back; no deadheading needed

Harvest Tips
This is an ornamental plant, not typically harvested for culinary use. Harvest cut flowers in early spring when blooms are fully open for fresh arrangements. Cut stems at base using sharp scissors; blooms last 1-2 weeks in water with fresh flower food. Leaves can be used fresh in early spring for medicinal tea preparation.
Fun Facts
- 🌱 The common name 'lungwort' comes from the Doctrine of Signatures—the spotted leaves resembled diseased lungs, so it was traditionally used to treat respiratory ailments in medieval herbalism.
- 🌱 'Mrs Moon' is named after a British gardener and is prized as superior to the species for its heavier silver variegation, making it an award-winning cultivar (winner of multiple horticultural society medals).
- 🌱 Pulmonaria flowers are pollinator magnets and exhibit a fascinating color-change mechanism: pink flowers shift to blue after pollination, likely signaling pollinators that the bloom has already been visited.
