Kalmia latifolia aka Mountain Laurel

Taxonomy

Kalmia latifolia, commonly known as mountain laurel, calico-bush, or spoonwood, is a bushy, evergreen shrub native to the eastern United States. It reaches a height of 1.5-1.8m and features lance-shaped, glossy dark green leaves. From late spring to midsummer, the plant produces large dome-shaped flowerheads with crimped cup-shaped salmon-pink flowers that open from reddish-pink buds. Mountain laurel is the state flower of Connecticut and Pennsylvania, and it is the namesake of Laurel County in Kentucky, the city of Laurel, Mississippi, and the Laurel Highlands in southwestern Pennsylvania. This shade-loving shrub has elliptical, glossy deep-green leaves similar to rhododendrons and gnarled stems, making it visually appealing throughout the year. It blooms with clusters of rose, pink, or white flowers with purple markings in late May to early June. If not deadheaded, it produces nondescript brown fruits. While mountain laurel has specific soil requirements, it is relatively easy to grow in the appropriate environment and complements rhododendrons and azaleas.

How to care for Mountain Laurel

Difficulty

Mountain Laurel presents a moderate level of care, which allows plant enthusiasts with some experience to expand their skills and knowledge.

Water

Mountain Laurel should be watered regularly, allowing the soil to dry out between waterings.

Soil

Mountain Laurel loves a well-draining soil. Perlite and vermiculite help with drainage, while coco coir adds organic matter, so a good potting soil mix will have all three. You can improve store-bought soil by adding some perlite to it.

Lighting

To ensure optimal growth, the Mountain Laurel prefers bright diffused light for 6-8 hours each day. Insufficient light can result in slow growth and leaf drop, so it's important to find a well-lit location for this plant. Place it near a window, within a distance of 1 meter (3 feet), to enhance its potential for thriving.

Dormancy

During the wintertime, it's common for Mountain Laurel to go dormant and their growth may slow down, so waterings should be spaced out more.

Toxicity

The toxicity level of this plant has not been officially confirmed by Ploi. If there is a possibility of ingestion of plant material with an uncertain toxicity by you, a family member, or a pet, it is advisable to seek the assistance of a medical professional.

Fertilizer

The growth rate of Mountain Laurel is slow and it doesn't necessitate additional fertilizing. By changing the soil in its pot annually, the plant should be provided with adequate nutrition. It is crucial to keep in mind that plants derive their energy from the sun, not fertilizers.

Region of origin

Mountain Laurel’s native range is Eastern N. America - New England to New York south to W. Florida.
