Hosta 'Cathedral Windows'
 

Hans Hansen of Minnesota registered this chemically induced tetraploid tissue culture sport of H. 'Stained Glass' in 2005 and 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 Diana 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."

Similar hostas include H. 'Avocado' and H. 'Holy Mole'.

Sports include H. 'The Shining'.

In an article in The Hosta Journal (2016 Vol. 47 No 2), the author described this plant's flowers as having a "Strong" fragrance compared to other hostas.


United States Patent: PP17295  (2006)
