Kalmia procumbens, commonly known as alpine azalea[1] or trailing azalea,[2] is a dwarf shrub of high mountain regions of the Northern Hemisphere that usually grows no more than 10 centimeters (4 in) tall. Originally named by Linnaeus as Azalea procumbens, it is also named after French botanist L.L.A. Loiseleur-Deslongchamps - Loiseleuria procumbens.

Distribution[edit]

Kalmia procumbens is not well known though it is widely distributed. These plants are common in the subarctic regions and high mountains of the northern hemisphere. In North America it reaches the southern limit of its range in the mountains of Maine, New Hampshire, New York, and Washington. It is easy to propagate.[citation needed]

Habitat and ecology[edit]

Kalmia procumbens prefers alpine or subalpine, rocky exposed habitat. It grows above treeline with mountain heathers and at lower elevations in bogs.[citation needed]

It is a known host to the microfungus Delphinella polyspora, which grows on its pedicels and fruit.[3]
