Mikiko Lockwood in an article on The Hosta Library titled,
A Little About Japanese Hosta Terms defines the term
kodakarasaki or kodakarazaki as having no English word
for this type of blooming habit - multiple flowers growing from on
pedicel, or within another flower (similar to "hose in hose").
cultivar name was mentioned in the Lockwood article with no further
details but we can probably expect that it is a hosta with different
type of bloom structure.
