This cultivar is an H. 'Tokudama'-type
plant with blue-green foliage. It was originated by
Mark Zilis but registered by
Peter Ruh of Ohio in 2002. The large
size mound grows to a height of around 19 inches with a
spread of around 40 inches. Its near-white flowers bloom in
clusters in July.
The Hostapedia by Mark Zilis (2009), "...I purchased a plant of what I thought was 'Blue
Moon'...and began propagating it by
tissue culture. After a
few years, a number of collectors began noticing that this
version of 'Blue Moon' was much larger than
Eric Smith's true
'Blue Moon' and dubbed it "Big Blue Moon". Finally, in 1990, I
named this mistaken plant 'Blue Splendor'."
