'''''Saussurea''''' is a genus of about 300 species of [[flowering plant]]s in the tribe [[Cardueae]] within the family [[Asteraceae]], native to cool [[temperate]] and [[arctic]] regions of [[East Asia]], [[Europe]], and [[North America]], with the highest diversity in [[alpine climate|alpine]] habitats in the [[Himalayas]] and East Asia. Common names include '''saw-wort''' and '''snow lotus''', the latter used for a number of high altitude species in East Asia.

They are [[perennial plant|perennial]] [[herbaceous]] plants, ranging in height from dwarf alpine species 5–10 cm tall, to tall [[thistle]]-like plants up to 3 m tall. The [[leaf|leaves]] are produced in a dense basal rosette, and then spirally up the flowering stem. The [[flower]]s form in a dense head of small [[inflorescence|capitula]], often surrounded by dense white to purple woolly hairs; the individual florets are also white to purple. The wool is densest in the high altitude species, and aids in the thermoregulation of the flowers, minimising frost damage at night and also preventing [[ultraviolet light]] damage from the intense high-altitude sunlight.

De Candolle named the genus after [[Horace-Bénédict de Saussure]] (1740-1799) and [[Nicolas-Théodore de Saussure]] (1767–1845).<ref>Candolle, A.P. de, in ''Annales du Muséum National d'Histoire Naturelle.'' 16:197-198</ref>

==Uses==
A number of the high alpine Himalayan species are grown as [[ornamental plant]]s for their decorative dense woolly flowerheads; they are among the most challenging plants to grow, being adapted to harsh climates from 3500–5000 m altitude, demanding cool temperatures, a very long (up to 8–10 months) winter rest period, and very good soil drainage in humus-rich gravel soils.

As the slow-growing wild plant is endangered by collections, a substitute grown in tissue culture has been suggested, which is mostly equivalent. Generally the analgesic and antiinflammatory effects of the plant are much inferior to those of [[indometacin]].

===Literature and culture===
In most Chinese martial arts literature, the snow Lotus was classified a rare herb as precious as [[lingzhi mushroom]], and old [[ginseng]].
