Description

Mountain laurel is one of the most beautiful native flowering shrubs. It can occasionally grow taller than 15' and be considered a small tree. The broad evergreen leaves are leathery. It produces spectacular clusters of cup-shaped, fragrant, white to deep pink flowers.

Cultivation

Kalmia latifolia prefers moist, rich, acidic, well drained soil. Conditions similar to those required for rhododendrons and azaleas. It is drought tolerant and may be planted in full sun so long as it is in a cool environment; as found in the higher elevations of its native range. Do not fertilize! May be in bloom for over 2 weeks, late spring to mid summer, depending on location: May- July. Zones 5-8

Propagation

Mountain laurel may be propagated by seed...with patience. It may be propagated by cuttings or layering, but this method also proves to be very difficult. Commercially available specimens are mostly propagated by tissue culture.

Additional Notes

Mountain laurel is the State flower of Connecticut. All parts of the plant are poisonous to humans and livestock. Deer resistant.
