Summary

Kalmia polifolia, commonly known as Bog Laurel, is an evergreen shrub native to acidic bogs, wetlands, and cold peat-accumulating areas in northern North America, including parts of Canada and the northern United States. It typically grows to a height of about two feet and is characterized by its small, leathery, blue-green leaves and clusters of deep pink to purple flowers that bloom in late spring to early summer. The flowers are showy and cup-shaped, attracting bees for pollination, but it is noteworthy that the honey produced from this plant can be toxic.

Bog Laurel is valued for its ornamental qualities, particularly its attractive flowers and compact size, making it suitable for rock gardens, bog gardens, and as a ground cover in acidic soil conditions. It requires consistently moist soil and can tolerate full sun to partial shade. While it is relatively low maintenance, it can be susceptible to leaf spot and other fungal diseases. Gardeners should be cautious when handling this plant, as all parts are toxic if ingested.CC BY-SA 4.0
