Hosta 'White Knight'
 

This cultivar of unknown parentage was registered by Peter Ruh of Ohio in 2004 and re-registered with new data in 2018 grows into a large size hosta about 19 inches tall and 35 inches wide. The foliage is medium to light green, ovate, flat and very shiny on top. Pure white, fragrant flowers bloom on scapes 17 to 20 inches tall from late July into August or later. The seed set was unknown at the time of registration.

The registration materials state: "...is different from 'Royal Standard' by having a dull underside of leaf; very fragrant...from the Krossa collection..."

According to The Hostapedia by Mark Zilis (2009), "...a long-standing cultivar name that was used by a few nurseries in the 1970s to evade the 'Royal Standard' patent...resulted in nearly all plants with this label being the same as 'Royal Standard'..."

This cultivar was originally registered as an H. plantaginea seedling but this was changed to Parentage Unknown in 2018.
