'Carol' Mountain Laurel produces beautiful flower clumps in May and June. The buds are red but the ballet shirt shaped flowers are pale pink to white when fully open. The shiny green foliage is evergreen and somewhat leathery. Kalmia 'Carol' is particularly showy when naturalized and planted in mass. As Kalmias mature, they can become picturesquely open in habit, but if a tighter evergreen is desired, they can be pruned yearly, preferably soon after blooming.
