According to The Genus Hosta by W. George Schmid (1991), this species is native to several Korean islands. It forms a small size plant about 8 inches high with a spread of around 18 inches. The leaves are dull green, smooth textured with petioles that have reddish dots. Pale purple flowers with purple anthers bloom in August. It produces viable seeds.

The Hostapedia by Mark Zilis (2009) reports, "Hosta jonesii is a recently identified Hosta species. Its merits in the garden or as a breeding plant are yet to be determined, but superficially it appears similar to Hosta tsushimensis. The species name honors Dr. Samual B. Jones, botanist from the University of Georgia."

The New Encyclopedia of Hostas by Diana Grenfell (2009) states: "In cultivation usually seen only in specialist collections."

W. George Schmid in his Hosta Species Update on The Hosta Library (2010) says, "H. jonesii is rarely seen in gardens. Virtually all of the material sold in the US under this name is incorrect. This is unfortunate, because it is an attractive species. In cultivation H. jonesii is much more vigorous in growth than H. tsushimensis and is an attractive horticultural item."
