In the early days of hosta cultivation in the home garden, if someone said they had the "variegated one" they were probably talking about Hosta 'Undulata Univittata'. The American Hosta Society registered it in 1987 by a former name of H. undulata 'Univittata'. It has been known under several other names until The Genus Hosta by W. George Schmid (1991) gave it the current name as a cultivar and not a separate species.

This sport of H. 'Undulata' is a medium size plant about 18 inches high by 45 inches wide. The deep green foliage has a creamy white medial (center) variegation. Its leaves are broadly elliptic, wavy and have smooth texture with a rounded base and curved tips. Pale lavender, striped flowers bloom from mid-July into August. It produces large numbers of flowers per scape.

From the Field Guide to Hostas by Mark Zilis (2014), "...differs from 'Undulata' by its much wider green margin...also more vigorous and has had a greater impact in American landscapes."

According to The Hostapedia by Mark Zilis (2009), this species has been known as H. 'Color Riot' in the past. It might have been sold at one time as Mackwoods No. 6.

This cultivar has been awarded the Royal Horticultural Society's Award of Garden Merit in the UK.
