W. George Schmid in his
Hosta Species Update in The Hosta Library (2008) states that
this is a non-registered sport of
which is rarely seen in Japanese gardens. It is a
Kenji Watanabe of
Gotemba Nursery in Japan. The leaves are green with a
yellowish-white medial (center) variegation that also
includes some streaking.
As a sport of H. montana, this plant is probably
a large size hosta with an upright growth habit and
medium green colored foliage. The leaves are deeply
veined, moderately wavy with a moderately lobed leaf
base. It has open funnel shaped, very pale lavender
flowers in July with bracts on the
flower scape after the flower opens. Plants of this species also tend to emerge early in the spring
and are often susceptible to damage from frosts if not
says that It is also known as H.
'Fuji Sunrise' but
the hosta we have by that name is a much smaller plant
H. sieboldii in its background. Perhaps the
'Fuji Sunrise' sold in Japan is different from the one
sold by that name in the U.S.
