Sheep Laurel (Kalmia angustifolia), also known as Lambkill, is a compact, colony-forming native evergreen shrub that brings vivid color and texture to naturalized gardens and resto ration landscapes. Growing approximately 3 feet tall and up to twice as wide, it forms low, dense thickets perfect for adding structure to boggy or woodland margins, moist acidic soils, and disturbed or rewilding areas. In early to mid-summer, Sheep Laurel bursts into bloom with clusters of bright pink to magenta, saucer-shaped flowers that appear just below its glossy, blue-green foliage. These showy blooms attract native bees, butterflies, and other beneficial pollinators, while the foliage transforms to reddish-purple hues in fall, adding seasonal color and evergreen interest throughout the year. This shrub also provides shelter and nesting cover for small birds and acts as a larval host plant for species like the Columbia Silkmoth (Hyalophora columbia) and Northern Blue (Plebejus idas) butterfly. Though highly valued by wildlife and gardeners alike, Sheep Laurel is toxic to livestock—its historical common name “Lambkill” reflects its potent chemical defense system. It is not browsed by deer, which makes it a good option in areas with high deer pressure.
