This sport of H. 'Undulata
Albomarginata' is a non-registered hosta from
W. George Schmid of Georgia. The leaves emerge nearly white in the
spring but turn a bit greener as the season progresses.
Ohatsuki Gibōshi, the "white leafy-scaped hosta," is
a white form that occurs from time to time as a mutation
in cultivated H. 'Undulata Albomarginata'
colonies. It has been reported in Japan and on several
occasions in the United States. Its leaves are a uniform
near-white with a scarcely noticeable greenish-yellow
tint, the overall impression being white. A difficult
subject in cultivation - hence the name - because of its
lack of chlorophyll. The Japanese cultivate it in pots
so it can be moved around. It makes a fine showing in
spring when it requires shade, but later it must be
grown in sun so that the white-streaked, green summer
leaves can build up enough food for survival. Its other
morphological features are like H. 'Undulata'
except that the leaves are flat and, being a difficult
subject, it is definitely for experienced collectors
Mikiko Lockwood in an article on The Hosta Library titled,
A Little About Japanese Hosta Terms defines the term ohatsuki as leafy flower scape.
