This broadleaf evergreen shrub grows to a height of 12 to 15 feet and spreads to 12 feet. The growth rate is less than 12 inches a year. Mountain laurel requires an acid, well-aerated soil. It tolerates shade, but some exposure to sun is required for proper flower color development of red and pink cultivars. The foliage is thick and leathery with a dark green color at maturity.

Mountain laurel is native to dry rocky woodlands, slopes and streambanks from Florida to Canada.

This shrub can be used in borders, foundation plantings, screen, massing and as a specimen plant. Mountain laurel’s cultural requirements are similar to those of rhododendron and azalea, so they can be grown together.

Mountain laurel is susceptible to scale insects, lacebug, whitefly and borers. Cercospora leaf spot is found on almost all mountain laurels. This fungus causes irregular to circular spots on the leaves of mountain laurel throughout the Appalachian region. Severe infection seems to stunt plant growth and suppress flowering, particularly on plants growing in moist, shady places. The spots are 2 to 4 inches across, at first medium to dark brown on both surfaces, but fading to grayish brown in the center of the upper surface. The margin remains dark brown to purplish brown.
