Rhododendron hirsutum (NL: Harig alpenroosje / EN: Hairy Alpenrose, Alpine Rose / DE: Bewimperte Alpenrose, Almrausch, Almenrausch oder Steinrose / FR: Rhododendron cilié, Rhododendron hirsute ou Rhododendron poilu) is one of the species of rhododendron native to the mountains of Europe. is found in the Central and Austrian Alps, the Italian Dolomites, and the mountains of Slovenia growing on or adjacent to limestone at elevations from 600-2500. It grows in woodlands, screes, among dwarf pine and moorland. R. hirsutum is a compact to broadly upright shrub to 1 m. The scaly branchlets usually have bristly hairs or very short hairs. The evergreen leaves are held 2 years and are obovate to oblanceolate. Although an alpine plant, it needs a closed snow cover in winter because it is frost sensitive. Linnaeus described it in 1753 with the species epithet "hirsutum"meaning "hairy". It, like the acid-loving species R. ferrugineum, is commonly called the "Alpine Rose" emphasizing the need for scientific name usage.
