Armeria maritima is a compact evergreen perennial native to coastal cliffs, salt marshes, and rocky shorelines across Europe and North America. It forms tight, grass-like mounds and sends up slender stems topped with dense globe-shaped heads of pink flowers in late spring and early summer. Its salt tolerance, drought resistance, and tidy habit make it well suited to rock gardens, border edges, and xeriscape plantings.
Excellent drainage is essential; the plant rots in heavy or consistently wet soil. Low fertility suits it best — rich soil favors leafy growth over flowering. Avoid mulching around the crown. It tolerates a pH of 6.0–7.0 and thrives in poor, sandy, or gravelly soils. Clumps may die out in the center after several years; divide in early spring to rejuvenate them. Cold-hardy to zone 3 and highly tolerant of salt spray and wind, making it a reliable choice for coastal and exposed sites.
Armeria maritima has a documented history of folk medicinal use in parts of Europe, recorded for external antiseptic application and for urinary and thyroid complaints. The plant contains plumbagic acid and armericin, compounds that have been studied for antimicrobial activity.
Crown Rot
Lower leaves yellow and wilt; the base of the rosette turns brown and soft, sometimes with white fungal threads at the soil line. Plants collapse in wet conditions.
Remove and destroy affected plants. Improve drainage and avoid overhead watering. Do not mulch directly against the crown. Space plants for airflow and avoid replanting in the same wet spot.
Rust
Orange to brown raised pustules on the undersides of leaves, with yellow spotting on the upper surface. Heavy infections cause leaves to yellow and drop.
Remove and destroy infected leaves. Avoid overhead watering and improve air circulation. Apply a sulfur or copper-based fungicide if it spreads. Clear plant debris in fall.
Phytophthora Root Rot
Wilting despite moist soil, yellowing leaves, stunted growth, and dark, decayed roots and crown tissue. Vines may collapse during hot weather.
Plant in well-draining soil and avoid waterlogging. Remove and destroy affected vines. Improve drainage with raised beds or amended soil and avoid overwatering.
