From wikipedia: Hosta (syn. Funkia) is a genus of about 23–45 species of lily-like plants in the family Asparagaceae, subfamily Agavoideae, native to northeast Asia. They have been placed in their own family, Hostaceae (or Funkiaceae); like many ‘lilioid monocots’, they were once classified in the Liliaceae. The scientific name is also used as the common name; in the past they were also sometimes called the Corfu Lily, the Day Lily, or the Plantain lily, but these terms are now obsolete. The name Hosta is in honor of the Austrian botanist Nicholas Thomas Host. The Japanese name Giboshi is also used in English to a small extent. The rejected generic name Funkia, also used as a common name, can be found in some older literature. […]
