Hosta 'Tonoko Tachi'
aka H. rectifolia pruinosa

This cultivar is a sport of H. rectifolia from Japan which was first named by Dr. Fumio Maekawa around 1940. It is a large size plant about 19 inches high by 32 inches wide with shiny, medium green colored foliage. The leaves are moderately corrugated, wavy and have good substance. Medium purple flowers bloom from late July into August.

From the Field Guide to Hostas by Mark Zilis (2014), "It can be found amongst grasses and other perennials in full sun within a few hundred meters of the Japan Sea...has been marketing this plant under the cultivar name 'Tonoko Tachi for a few years, though this contradicts a statement I made on page 957 of The Hostapedia. I stated that Tonoko Tachi "is not a cultivar but a Japanese common name for H. rectifolia pruinosa..." Obviously, I changed my thinking a bit on the subject and now consider 'Tonoko Tachi' an acceptable name for marketing purposes."

Mikiko Lockwood in an article on The Hosta Library titled, A Little About Japanese Hosta Terms defines the term tachi as upright, 'Tachi Gibōshi' or H. rectifolia.
