Hosta sieboldiana is a deciduous herbaceous perennial with a clump forming habit. Its waxy mid green leaves are cordate shaped with entire margins, deeply veined, up to 30cm long and 20cm broad. Its white/ pale purple flowers are funnel shaped and appear on erect spikes which are up to 75cm tall. Its roots are stolons which aids its spread.

Hosta sieboldiana, commonly known as the Giant Hosta or Plantain Lilly, is native to north east Asia.

The etymological root of the binomial name Hosta is named after the Austrian botanist Nicolaus Thomas Host (1771 to 1834). Sieboldiana is named after Philipp Franz von Siebold (1796 – 1866), a German plant collector in Japan.

The landscape architect may find Hosta sieboldiana useful as a low ground cover plant with architectural leaves, particularly in shady locations and is suitable for woodland planting schemes.  Snails may be a problem in damp locations.

Ecologically, Hosta sieboldiana is attractive to nectar loving birds.
