Hosta is a genus of about 23–40 species of lily-like plants in the family Agavaceae, native to northeast Asia. The scientific name is also used as the common name; in the past they were also sometimes called the Plantain lily, but the term is now obsolete. 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. Taxonomists differ on the number of species; as such, the list at the right may be taken loosely. The genus may be broadly divided into three subgenera. Interspecific hybridization is generally possible, as all species have the same chromosome number (2n = 2x = 60) with the exception of H. ventricosa, a natural tetraploid that sets seed through apomixis. Many varieties formerly described as species have been taxonomically reduced to cultivar status, while retaining Latin names resembling species (e.g. H. 'Fortunei').
They are herbaceous perennial plants, growing from corms or rhizomes, with broad lanceolate or ovate leaves varying widely in size by species from 3–40 cm long and 2–30 cm broad. Variation among the numerous cultivars is even greater, with clumps ranging from less than 10 cm across to more than 2 m across. Leaf color in wild species is typically green, although some species (e.g. H. sieboldiana) are known for a glaucous waxy leaf coating that gives a blue appearance to the leaf. Natural mutations (sports) of native species are known with yellow-green ("gold") colored leaves or with leaf variegation (either white/cream or yellowish edges or centers).
The flowers are produced on an erect panicle up to 80 cm tall; the individual flowers are usually pendulous, 2–5 cm long, with six tepals, white, lavender, or violet in colour and usually scentless. The only strongly fragrant species is Hosta plantaginea, which is also unusual in that the flowers open in the evening and close by morning. This species blooms in late summer and is sometimes known as "August Lily".
