Sheep Laural also is known as Lambkill is a shrub in coastal New York. Isn't it a really cool looking flower?
The shrub itself is an evergreen.
Your vision of how other Kalmia (click here) look may influence you to envision a much different plant than this radically different Kalmia with blue-green, almost needle-like evergreen foliage that forms a much smaller, low, dense shrub at maturity. Sheep Laurel's closest match for looks might be a mature Rosemary plant with similar size and texture making it perfect in a small garden or rock garden. This Kalmia produces small rose-pink flowers from June into July that are set off perfectly by its foliage color. One of the hardiest plants in cultivation, it performs best in moist well-drained soils with light shade as its preferred exposure and is a great addition to the native shade garden.
