H. 'Silver Frost' × H. 'Blue Moon' hybrid was registered by Don Dean of Minnesota in 1999. The
medium size plant grows to about 14 inches tall and 38 inches
wide with very broadly ovate to round leaves that are often
cupped and unruly. Its very pale purple flowers bloom in July
followed by viable seeds.
The Hostapedia by
Mark Zilis (2009), "The intensity of blue coloration
in 'Silver Bay' is quite
impressive. Add to that intense
corrugation, an unruly nature, and thick substance and you have
a cultivar that should rank near the top of any list of best
blue hostas. Thank you Don Dean for developing this plant!."
The New Encyclopedia of Hostas by
Grenfell (2009) states: "...it is one of the few H. 'Elegans'cultivars that retain its blue color into the autumn...the
winner of the Alex J. Summers Distinguished Merit Award 2008 as
his most outstanding introduction."
