Lapland rosebay

Rhododendron lapponicum (L.) Wahlenb.

Lapland rosebay brings the woody structure of a shrub down almost to ground level. In the Canadian Arctic flora, plants commonly stand only five to ten centimeters tall, though sheltered sites can support much taller, upright growth. Exposed shoots may instead trail close to the ground. Canadian Museum of Nature: Flora of the Canadian Arctic Archipelago, Rhododendron lapponicum

Recognizing the plant

Its persistent leaves alternate along the stems on very short stalks. Blades are elliptical to narrow and widest toward the tip, generally 4–12 mm long, with smooth margins. A few fragrant flowers gather together, their joined petals opening into five purple lobes that fade toward pink. The anthers release pollen through pores at their tips. Small, conical capsules follow, opening at the top to release numerous tiny seeds. Canadian Museum of Nature: Flora of the Canadian Arctic Archipelago, Rhododendron lapponicum

Native range

Kew places the species across subarctic regions and south into the north-central and northeastern United States. In Arctic Canada it inhabits dry tundra, slopes, ridges and meadows, often on rocky or gravelly ground with little accumulated organic matter.
