The large white medial
variegation of this hosta accounts for its name. It is a sport
of H. 'Krossa Regal'
which grows about 15 inches tall with a spread of 35 inches.
Pale lavender flowers bloom from mid-July into August. This cultivar was registered by
Peter Ruh in 1999 on behalf of
who introduced it around 1971.
Since this cultivar lacks chlorophyll in much of the leaf
surface area, it produces thin leaf tissue. This is more easily
damaged by hot, dry weather and may be more attractive to slugs.
It also makes it a rather slow growing, tender plant overall.
The Hosta Handbook by
Mark Zilis (2000), says that this is the stable form of a streaked plant once known as
Hosta fortunei 'Krossa Variegated' that was available
The Hostapedia by
Mark Zilis (2009),
"Probably its main claim to fame is being the mother plant of 'Night
before Christmas' which has a much better growth rate."
