Hostas are native to northeast Asia, specifically China, Japan, Korea and the Russian Far East. They grow in moist, shaded places and are valued in gardens as shade-tolerant foliage plants, hardy in zones 3 to 8 or 9.
Most of the species behind modern hostas were brought from Japan to Europe by Philipp Franz von Siebold in the mid-19th century. The genus was named by Leopold Trattinnick in 1812 for Nicholas Thomas Host, and the older name Funkia honours Heinrich Christian Funck. Hosta plantaginea, the only strongly fragrant species, is often called August lily. The American Hosta Society registers cultivars, with over 7,200 registered or reserved names.
