Sea lungwort - Mertensia maritima (Care, Characteristics, Distribution, Images)

Sea lungwort

Also known as: Oysterplant, Northern shorewort

The sea lungwort is also called "oysterleaf" because in some situations the texture of and scent of its leaves resembles that of oysters. The seeds are very resilient against seawater - a fact that allows them to disburse via the ocean currents. Sea lungwort makes for a good garden plant, but it does tend to attract slugs and snails.

Water: Sea lungwort thrives in moist, saline conditions, requiring consistent moisture without waterlogging. Weekly watering is ideal, and outdoor growth benefits from natural rainfall. As an herbaceous perennial, sea lungwort requires reduced moisture during dormancy in colder months, correlating its needs with seasonal temperature changes.

Fertilize: For sea lungwort, feed with balanced fertilizers monthly during spring and summer at half-strength, and quarterly in winter. Use liquid fertilizers for better uptake, and ensure soil is moist before application. Avoid over-fertilization and root burn by diluting correctly and not applying directly on foliage.

Pruning: Sea lungwort thrives in coastal areas, featuring fleshy, bluish-green leaves and bell-shaped flowers. Prune from early to late spring, removing dead foliage and spent stalks to boost growth. Clean tools to minimize infection risk, enhance airflow, and promote healthier plants and optimal blooms.

Propagation: Propagation of sea lungwort is best done through division, separating clumps into smaller sections with healthy roots. Each division is a clone of the parent, ensuring quick establishment. Proper handling minimizes stress, promoting rapid recovery and growth for each new plant.

Repotting: Repot sea lungwort in early spring every 2-3 years in a wide, shallow pot to maintain its compact form. Post-repotting, keep the soil moist and provide indirect light. Adjust watering periodically to mimic its coastal habitat and support its unique foliage.
