Hosta 'Undulata' Group

In 1991, the comprehensive book about hostas, The Genus Hosta by W. George Schmid, was published. It was the first intensively researched book about the entire genus which, until that time, suffered from a lot of misinformation and name confusion. As the result of his research, Schmidt determined that several of the plants previously treated as separate, naturally occuring, species were, in fact, cultivated varieties, i.e. cultivars. created by nurseries or hybridizers.

This is one of the hosta groupings that was shifted from species to cultivar status. For more on this process...

Species switched to cultivar status in 1991 include:

Hosta 'Undulata'

This cultivar of unknown parentage came from Japan and has been a part of American gardens for decades. It forms a medium (12 inches high) mound of narrowly elliptic foliage with thin substance. Pale lavender flowers appear in July.

According to The Hostapedia by Mark Zilis (2009), it was "...named as a species Hosta undulata by Liberty Hyde Bailey in 1923...but reduced to cultivar status, i.e., H. 'Undulata', by The Genus Hosta by G. Schmid (1991)...registered by the American Hosta Society in 2001 for Liberty Hyde Bailey...sold under a wide variety of names, including H. undulata variegata, 'Color Accent', H. koreana 'Variegated'...H. 'Medio-variegata' = H. 'Undulata'...

...Long rows of 'Undulata' still can be found around homes and in the parks of many U.S. cities. Its overuse and tendency to be voraciously attacked by slugs, however, caused it to gain a bad reputation...I maintain, though, that 'Undulata' is a beautiful hosta."

Seedlings or sports of this cultivar include H. 'Kiwi Spearmint', H. 'Outhouse Delight', and H. 'Purple and Gold'.

Similar cultivars include .
