Mountain Laurel Overview

Kalmia is a genus containing around 9 species of evergreen shrubs in the Ericaceae family. They originate from Eastern North America and Cuba where they are found in regions with acid soil, some species native to boggy areas and others from dry sandy habitats. Commonly known as Mountain Laurel, Alpine Azalea and Trailing Azalea. Several species are cultivated for their attractive Rhododendron-like umbels of bowl-shaped flowers in shades of purple, pink and white. These plants are toxic and should be grown away from grazing livestock.
