Plant Collector: Kalmia latifolia “Nipmuck”

Kalmia latifolia “Nipmuck”

Just when all the spring flowering trees and shrubs have passed over and we move into early summer, the kalmias open. They look as if they belong in the spring group and they like to grow in similar conditions to rhododendrons and camellias but their blooms take us into December. This one has the rather odd name of “Nipmuck” and is the darkest variety we grow. I failed to find out how it came by its name but would guess it may derive from the indigenous people of America.

In leaf, these slow growing, evergreen shrubs are pretty anonymous. But when the buds appear, they look like piped icing such as often adorns wedding cakes, opening to little cups, chalices maybe. The backs of the petals are white with just the red shading through from the inside.

Kalmias are native to North America, though only to the east coast where they stretch from Canada to as far south as Mexico. Locals call them the Calico Plant or Mountain Laurel. Most of the prized garden selections are forms of latifolia which is hardy. In other words it won’t be harmed by cold winters of the type we get in New Zealand, even inland, southern areas. They belong to the ericaceae family.

There is nothing rare about kalmias but they are very difficult to propagate from cutting so you may find them hard to source. When you do find them for sale, be prepared to pay a decent price for one. Cheap plants are cheap to produce so difficult ones should command a higher value.

From 2009, Kalmia Ostbo Red.
