Plant Profile: Andromeda polifolia

Andromeda polifolia, commonly known as Bog Rosemary, is a low-growing evergreen shrub or ground cover that typically reaches heights between 8 inches and 3 feet. In its natural habitat, it is predominantly found in bog environments. This shrub tends to have few branches, but multiple plants can cluster together to form a dense group. It thrives in well-drained, moisture-retentive soil that is rich in humus and free of lime, preferring shaded areas. The plant struggles in hot and humid conditions, particularly in regions south of Zone 6. It spreads gradually through suckers, making it an attractive ornamental choice. The leaves are small, firm, and narrow, exhibiting a blue-green hue with rolled-under edges. At the end of its branches, clusters of small, bell-shaped flowers bloom in shades of pink or white, arranged in a curved umbel.

Bog Rosemary belongs to a group of heath shrubs that includes Leatherleaf, Sheep Laurel, Bog Laurel, and Labrador Tea. In certain cultures, the young leaves and shoot tips are used to brew a fragrant tea; however, caution is advised, as boiling the plant or steeping it in hot water can release a toxic compound. A safer method is to prepare 'sun tea' by soaking the leaves in a jar of water placed in direct sunlight.

Regarding plant health, there are no known diseases or insect pests that affect Bog Rosemary, although it does require acidic soil for optimal growth.
