This is a small to medium
size hosta with slightly waxy, medium green foliage that
has a narrow, yellow to creamy white marginal
variegation. Lavender flowers with purple stripes bloom
on scapes 14 inches tall in August followed by viable
seeds.
There seems to be
a lot of confusion over this fine hosta as evidenced by
the following comments from Mark Zilis. It appears that
he is saying that H. 'Opipara' is actually H. 'Bill
Brincka' but it could also be H. 'Koriyama' which could
be H. 'Opipara Koriyama' which is the same as H. 'Mishima
Fukurin Koba'...is that clear?
RE: H. 'Opipara' - Mark Zilis (2009) says, "...'Opipara' (or 'Bill Brincka') should be in every hosta
collection...In the 1980s, however, I would not have given this
plant such a glowing recommendation. Nearly every plant of 'Opipara'...in
the United States was infected with a virus (probably
Hosta Virus X). Fortunately,
Bill Brincka... obtained
a clean selection of this plant, which was marketed under his
name..."
RE: H.
'Koryama' - According to
The Hostapedia by Mark Zilis (2009), "When I first encountered this
plant in the 1980s, it was purported to be a dwarf-size
Hosta opipara, listed as
Hosta opipara 'Koriyama'. A
lot has changed since that time. Hosta opipara is now considered
a cultivar (H. 'Opipara') and 'Koriyama' is the proper spelling
for the plant (named for a mountain in northeastern Japan). More
importantly, 'Koriyama' appears to be the same as 'Mishima
Fukurin Koba', a form of Hosta sieboldii!"
RE: H.
'Bill Brincka' - Mark Zilis (2009) states, "...represents a
virus -free
version of 'Opipara'. Most 'Opipara' specimens in the U.S. were
infected with a virus (probably
Hosta Virus X) before
Bill Brincka imported this clean plant from
Japan. By whatever name,
the plant is simply magnificent."
Mikiko Lockwood in an article on The Hosta Library titled,
A Little About Japanese Hosta Terms defines the term koba as small leaf,
'Koba Gibōshi' or
H. sieboldii, the term fukurin as margined or edged. and the term yama as mountain.
