You can grow Kalmia latifolia 'Nathan Hale' as a handsome, broadleaf evergreen shrub that brings glossy, leathery foliage and dramatic late-spring bloom to woodland edges and foundation plantings.
In spring, you will see clusters of cup-shaped flowers in shades of pink to white with purple markings. The plant typically matures to about 7-8 ft tall and 7-8 ft wide, forming a dense, rounded outline that adds structure all year.
For best results, site it where you can provide morning sun with shade from early to mid-afternoon. It tolerates a wide range of light from sun to shade, but it performs best in partial shade, especially where summers are warm. Shelter from harsh drying winds helps keep foliage looking its best.
Give it cool, moist, acidic, humus-rich, well-drained soil. Mulch to keep the root zone cool and evenly moist, and avoid heavy clay and poorly drained sites. Water regularly during establishment, then keep soil consistently moist without staying soggy.
Light pruning after bloom can help maintain a full shape. Remove spent flower clusters promptly if you want a tidier look and to encourage new growth. All parts of mountain laurel are toxic if ingested, so place it thoughtfully around children and pets.
