Kalmia latifolia 'Nipmuck'


Back in 1971, geneticist and plant breeder Richard Jaynes was working to develop new and interesting cultivars of mountain laurel at the Connecticut Agricultural Experiment Station in New Haven, CT. His curiosity and love of mountain laurels resulted in ‘Nipmuck’, one of the more outstanding cultivars created. Named after the Nipmuck State Forest in Connecticut, this mountain laurel is a slow-growing, rounded evergreen that reaches 4-5 feet tall and 4 feet wide in ten years. In late winter, red flower buds form in large clusters carried at the ends of the branches, and in spring these buds open to ample numbers of light pink flowers with dark pink petal backs. Quite often, red buds and pink open blooms appear at the same time, which is a sight to see. Evergreen. Plant in part shade in cool, moist, acidic, compost-rich, well-drained soil. Water well when blooming and avoid excessive pruning. Does not like clay soils. Looks lovely in a woodland garden or other naturalized setting.


Nipmuck will begin shipping on February 10, 2022

Mountain Laurel look great when planted with Rhododendron and/or Azalea. They have smaller leaves but boom almost at the same time as the Rhodies, early May for us in NC. If you love Mountain Laurel or want to try the for the first time, be sure to plant them very high and use well draining soil so that thier roots do not stay wet as they will rot very quickly. In the nursery, we water them very lightly and not after 2pm.

A relative of the rhododendron, the common mountain laurel is native to Eastern North America (New England, southern Indiana, Louisiana, and the Florida panhandle) and is frequently found in pine, spruce, and fir forests. Mountain laurels were often called ‘Spoonwood’ by Native Americans, as they fashioned wooden spoons from the gnarled trunks of mature plants. All parts of the mountain laurel plant are toxic if ingested and are poisonous to horses, goats, cattle, sheep, and deer. 

Be sure to use a well drained soil medium when planting any Mountain Laurel as they prefer fall planting with less watering than you might think. In NC our soil is clay so we prefer to use pine bark soil conditioner when planting Camellia, Rhododendron, Mountain Laurel, and Azalea.
