With Kalmia latifolia 'Goodshow' (Mountain Laurel 'Goodshow'), you can bring year-round evergreen structure and a big late-spring floral show to your landscape.
You'll get a dense shrub that typically matures about 72-96 inches tall. In season, it carries clustered, cup-shaped blooms that range from white to rose and often show distinct markings inside each flower, giving the plant a detailed, patterned look up close.
For best performance, plant in cool, consistently moist but well-drained, acidic soil rich in organic matter. Set it where it receives part shade, such as morning sun with afternoon shade, though it can tolerate more sun when soil moisture is dependable. Mulch helps keep roots cool and reduces drying between waterings.
After flowering, you can lightly prune to shape and to encourage a bushier habit; avoid heavy pruning at the wrong time since next year's flowers develop on older growth. Because mountain laurel is poisonous if eaten, place it thoughtfully around pets and small children and wear gloves if you are sensitive when handling foliage.
