Hans Hansen of Minnesota registered this
tissue culture sport of H. 'Stained Glass' in
Shady Oaks Nursery of Minnesota received a U.S. patent
in 2006. The tetraploid nature of the plant allows it to have a
thicker leaf substance and a wider dark green margin than the
mother plant. Its flowers are pale lavender, fragrant and are
borne in August.
The New Encyclopedia of Hostas by
Grenfell (2009) states: "Increases rapidly. Must be divided frequently to
retain the balance between
variegation and the wide leaf
margins...Differs from its parent in having thicker
leaves with much wider leaf margins which entirely
changes the balance of the leaf colors."
In an article in
Hosta Journal (2016 Vol. 47 No 2), the author
described this plant's flowers as having a "Strong" fragrance
compared to other hostas.
