Kalmia procumbens (L.) Gift, et al. ex Galasso et al.
Habitat: Peaty or rocky exposed habitats. [Alpine or subalpine (non-forested, upland)]
Range: Circumboreal, south to the higher mountains of Maine, New Hampshire, and New York.
Aids to Identification: Alpine-azalea is a small woody shrub which forms bushy clumps usually no more than 10 cm high. The leaves are opposite, evergreen, leathery, and only 5-8 mm long. The pink or white flowers grow in clusters from the upper leaf-axils and are shaped like a crown due to fusion of the lower half of the petals and mature as a 2- or 3-valved capsule.
Ecological characteristics: In Maine, this species is found above treeline on Mt. Katahdin.
Phenology: Flowers June - August.
Synonyms: Azalea procumbens L.; Chamaecistus procumbens (L.) Kuntze.; Loiseleuria procumbens (L.) Desv.
Known Distribution in Maine: This rare plant has been documented from a total of 1 town(s) in the following county(ies): Piscataquis.
Reason(s) for rarity: An arctic species disjunct from its principal range.
Conservation considerations: Unscrupulous people have been known to pluck up alpine azalea plants from Katahdin for alpine-themed gardens; this is illegal and could be harmful to the population. Wild plants need to be left undisturbed.
