This is a commonly occurring tissue culture sport of H. 'Sagae' which was registered by Mark Zilis of Illinois in 1999. The giant size (31 inches high) cultivar is known for its upright form. The foliage is wavy and deeply lobed at the base. It produces pale lavender flowers on scapes up to 50 inches tall from mid-July into August.

 

According to The Hostapedia by Mark Zilis (2009), "...has been a colossal failure. It is a very poor grower and certainly is a test for the most ardent collector. 'Ōgon Sagae' apparently is different from this plant and is a much better grower."

Mikiko Lockwood in an article on The Hosta Library titled, A Little About Japanese Hosta Terms defines the term ogon or oogon as gold or yellow.
