Lungwort Plant Care

Lungwort (Pulmonaria saccharata) belongs to the Boraginaceae family within the Pulmonaria genus. Lungwort is native to France and Italy. Lungwort is also known as Bethlehem Sage, Spotted Lungwort, Sugar Lungwort.

Lungwort displays a low rosette, spreading growth habit, reaching up to 0 inches tall with a spread of approximately 0 inches. Lungwort produces tubular flowers in shades of blue, pink, or white that change color as they mature.

Leaf size: approximately 0 inches.

Pulmonaria saccharata requires watering every 0 days. Allow the top layer of soil to dry between waterings to prevent root rot. Reduce watering frequency during winter when growth slows.

Lungwort thrives in partial to full shade light conditions. The optimal light range is 0–0 lux. Avoid placing Lungwort in direct, harsh sunlight for extended periods, as this can scorch the foliage.

Pulmonaria saccharata grows best at temperatures between 0°F and 0°F. Lungwort prefers humidity levels of 0–0%.

Moist, well-draining soil rich in organic matter. Good drainage is essential for Lungwort to prevent waterlogging, which leads to root rot and fungal issues.

Repot every 2-3 years in early spring. Choose a pot one size larger than the current container, and ensure it has drainage holes to allow excess water to escape.

Lungwort can be propagated through division, seeds.

Lungwort is susceptible to slugs, snails, powdery mildew. Inspect the foliage regularly, especially along leaf undersides and stems. Treat infestations promptly with insecticidal soap or neem oil to prevent spread.

Lungwort grows outdoors in USDA Zone 3a – 8b. Native to France and Italy, Lungwort is adapted to warm climates. In cooler regions, grow Lungwort as a houseplant or bring it indoors before the first frost.
