A streaked form of
Japan, it forms a large size mound.
The Hosta Handbook by Mark Zilis (2000), "Don't confuse 'Shuho
Nishiki' with 'Shunko Nishiki'. Both are variegated sports of
H. montana, but 'Shuho Nishiki' has a streakier foliage."
Mikiko Lockwood in an article on The Hosta Library titled,
A Little About Japanese Hosta Terms defines the term nishiki as brocade (rich-colored woven fabric) i.e.
something colorful and beautiful.
