Lapland rosebay is a small, evergreen, circumpolar alpine and arctic subshrub with violet-purple funnel flowers. It grows from prostrate mats to shrubs up to about 1 m, and spreads by rhizomes. It needs cool conditions and open, well-drained, acidic soil, so it is best suited to cold-climate or alpine gardens rather than typical lowland gardens.

About

Rhododendron lapponicum is a dwarf species of Rhododendron native to arctic and subarctic regions of North America, Europe, and Asia. It is commonly known as Lapland rosebay, rhododendron de Laponie in French-speaking Canada, qijjuttaaqpait tipilitt (ᕿᔾᔪᑦᑖᖅᐸᐃᑦ ᑎᐱᓕᑦᑦ) in Inuktitut-speaking regions of Canada, and gāoshān dùjuān (高山杜鹃) in China. The specific epithet lapponicum was given to the species by Carl Linnaeus, naming it after the Swedish region of Lapland.

Where it grows

R. lapponicum has a wide-ranging circumpolar distribution, occurring in arctic and alpine tundra environments across northern North America, northern Europe, and northeastern Asia. It grows at elevations ranging from sea level to 1,900 m (6,200 ft). It may be found in rocky barrens, heaths, bogs, beach ridges, or sandy stream banks. In eastern alpine ecosystems, it is commonly associated with cushion-tussock and heath-shrub-rush plant communities.
