This is a non-registered sport of
H. 'Tardiflora' of unidentified origin . It has green foliage with
yellow medial (center) variegation. The medium size (12 inches
high) plant bears lavender flowers late in the season and may
not have time to mature and set seed before frost in many
is in Japan called Kinakafu Aki Gibōshi, the "aureonebulosa Aki hosta"
but Aki Gibōshi is
H. longipes f. sparsa (purple anthers), not
H. 'Tardiflora' (yellow anthers), so the true form of Aki Gibōshi (H.
longipes f. sparsa) has mediovariegated mutations, but it probably does.
This cultivar is a sport with a yellow center and green margin or a center
clouded with yellow. A stable and viridescent form exists. Aside from the
variegation it is identical to H. 'Tardiflora'. A host offered as
tardiva aureostriata hort. in the United states is not related but belongs
to the H. sieboldii complex, the main difference is the much heavier
substance of the leaves and the much later blooming habit of the variegated H.
'Tardiflora'. Most clones of this cultivar are viridescent. It is available and
of interest to the collector."
Mikiko Lockwood in an article on The Hosta Library titled,
A Little About Japanese Hosta Terms defines the term kinakafu or ki nakifu as yellow-center(ed).
