Hosta is a genus of about 2345 species of plants commonly known as hostas, plantain lilies (particularly in Britain) and occasionally by the Japanese name giboshi. Hostas are widely cultivated as shade-tolerant foliage plants. The genus is currently placed in the family Asparagaceae, subfamily Agavoideae, and is native to northeast Asia. Like many 'lilioid monocots', the genus was once classified in the Liliaceae. The name Hosta is in honor of the Austrian botanist Nicholas Thomas Host. The rejected generic name Funkia, also used as a common name, can be found in some older literature. Hostas are herbaceous perennial plants, growing from rhizomes or stolons, with broad lanceolate or ovate leaves varying widely in size by species from 118 in (345 cm) long and 0.7512 in (230 cm) broad. The smallest varieties are called miniatures.
