Mountain Laurel is a broadleaf shrub known for its beautiful springtime blooms. The buds of the Galaxy Mountain Laurel open in late May to reveal star-shaped white flowers and burgundy accents. The flowers grow in clusters and are surrounded by long glossy green foliage that comes to a point. This plant is easy to maintain and can grow in conditions that other plants may find challenging.
This shrub is a vigorous grower that can be used as a border or specimen in a landscape. Kalmia latifolia naturally spreads, so feature this plant along a fence or a patio space to create privacy. The foliage stays in place year-round, so this plant still provides greenery and visual interest even after the flowers die back.
Galaxy Mountain Laurel Care
Galaxy Mountain Laurel loves shade, so plant in an area that receives 4 to 6 hours of sunlight. The ideal spot will also be protected from high winds, which can damage the branches. This shrub can handle full sun, but the growth may be impacted. Soil should be rich, well-drained, and slightly acidic. Mountain Laurel prefers damp conditions but allow the soil to dry out before watering.
Feed this Mountain Laurel using an acidic fertilizer in the spring. Let the plant grow naturally or trim it to fit your space during the early summer after the flowers fade away. Give the shrub a rejuvenating trim every few years if it becomes leggy.
Galaxy Mountain Laurel Spacing
This upright plant will grow 7 to 8 feet tall and wide. When creating a privacy screen or dense planting, Galaxy Mountain Laurel shrubs can be spaced 4 to 6 feet apart.

?
"Blooms on" tells you which stems produce flowers, which decides when it's safe to prune.
- New Wood: Flowers form on stems that grow this season. Prune in late winter or early spring without losing blooms.
- Old Wood: Flower buds form on last year's stems. Prune right after flowering. Pruning in fall or early spring removes next year's blooms.
- Both New and Old Wood: Blooms on last year's stems and again on new growth, so it flowers even after a hard winter or a mistimed pruning. Prune lightly after the first flush of blooms.
