}}Salvia canescens, the hoary sage, is a herbaceous perennial that is endemic to the Caucasus mountains. The specific epithet, canescens, refers to the off-white hairs covering the leaves.[1]Salvia canescens was first described in 1831 by the Russian botanist Carl Anton von Meyer.[2] The English botanist George Bentham applied the same name to a different species, which he corrected in his 1833 volume of Labiatarum Genera et Species by applying S. canescens Benth. as a synonym of Salvia pallida.[3][4] In 1992, the Russian botanist Y. L. Menitsky reduced the species Salvia daghestanica, originally described in 1951 by Dmitrii Ivanovich Sosnowsky,[5] to a variety of S. canescens, thus also requiring the autonym S. canescens var. canescens.[6]Salvia canescens var. daghestanica reaches nearly {{convert|1|ft|m|abbr=on}} tall and wide, forming a mound with snow-white {{convert|1|to|4|in|cm|abbr=on}} leaves that are covered with white hairs on top and bottom. It has royal purple flowers growing in whorls that bloom in summer and again in autumn, reaching just over {{convert|.5|in|cm|abbr=on}} long with a small calyx. Inflorescences grow to {{convert|1|ft|m|abbr=on}} long, holding the flowers above the foliage.[1] References1. ^1 {{cite book|last1=Clebsch|first1=Betsy|last2=Barner|first2=Carol D.|title=The New Book of Salvias|publisher=Timber Press|year=2003|pages=61–62|isbn=978-0-88192-560-9|url=https://books.google.com/books?id=NM0iwB8GrQYC&pg=PA61}} 2. ^{{IPNI|id=455879-1|accessdate=17 May 2010}} 3. ^{{IPNI|id=455880-1|accessdate=17 May 2010}} 4. ^Bentham, G. 1833.
