Pulmonaria 'Mrs Moon' is a charming woodland perennial prized for its attractive silver-spotted foliage and delicate pink-to-blue tubular flowers that bloom in spring. This cultivar is more ornamental than the species, featuring heavily variegated leaves that remain decorative throughout the growing season. It thrives in shaded garden settings and brings early color to woodland gardens and shade borders.

Growing Conditions

☀️
Sun: Partial to full shade; tolerates 2-4 hours of filtered morning sun; afternoon shade essential in warmer zones
💧
Water: Consistently moist but not waterlogged; water regularly during growing season (spring through early summer); reduce watering after flowering; drought-tolerant once established but performs better with adequate moisture
📏
Spacing: 12-18 inches apart inches
📅
Days to maturity: Flowers appear in first year from transplants; 2-3 years to reach mature size
🌱
Planting depth: Plant at same depth as nursery pot; crown should be at soil surface level

Soil

Type: Rich, well-draining woodland soil or humus-rich loamy soil
pH: 6.0-7.0

Growth Stages

1

Dormancy/Winter

November-February

Plant 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

2

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

3

Foliage Development

May-July

After 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

4

Summer Dormancy

July-September

Growth 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

5

Fall Senescence

September-November

Leaves 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

Aggressive spreading perennials (e.g., mint, Bishop's weed) Plants requiring full sun Drought-tolerant plants competing for space Very dry shade competitors

Common Pests

  • Ensure good air circulation; avoid overhead watering; reduce humidity; apply sulfur dust or fungicidal spray if severe; prune affected foliage

  • and

    Remove debris and dense ground cover where they hide; hand-pick at dawn; use beer traps or copper barriers; apply iron phosphate slug bait

  • Remove and dispose of affected leaves; improve air circulation; avoid wetting foliage; apply fungicide if widespread

  • Hand-pick if visible; maintain good garden hygiene; apply neem oil or insecticidal soap; rarely severe enough to require treatment

Uses

🍳

Herbal Tea & Infusions

Culinary

Young leaves can be harvested in spring and dried for herbal tea; traditionally used to support respiratory health and soothe coughs. The mild, slightly earthy flavor pairs well with honey. [source]

💊

Respiratory Support

Medicinal

The common name 'lungwort' derives from traditional use in supporting respiratory health, likely due to the leaf spotting resembling lung tissue (Doctrine of Signatures). Contains mucilage and silica compounds. [source]

🏠

Fresh Cut Flowers & Arrangements

Household

Delicate spring flower spikes are excellent for small bouquets, woodland arrangements, and cottage garden displays. The variegated foliage adds texture and interest to fresh or dried arrangements. [source]

🦋

Early Pollinator Nectar Source

Wildlife

One of the first spring flowers to bloom, providing essential nectar and pollen for bumblebees, honeybees, and other early-season pollinators emerging from dormancy. [source]

Garden Design & Ornamental Foliage

Craft

Prized by gardeners for its striking silver-spotted leaves that provide season-long visual interest in shade gardens; the contrast between blooms and variegated foliage makes it a focal point in woodland plantings. [source]

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.
