Bob Solberg of Green Hill Farm in North Carolina registered this cultivar in 2000. It is the result of a cross between H. 'Blue Arrow' × H. 'Sea Fire'. The plant grows into a medium size hosta about 14 inches in height with a spread of 36 inches. Leaf blades are narrowly ovate, are slightly wavy, have red petioles and have a little corrugation. From mid-July into August, it bears very pale lavender flowers.

The New Encyclopedia of Hostas by Diana Grenfell (2009) states: "Grow at eye level to feature the attractive mauve petioles, which are unusual in a hosta with this leaf color."

A Photo Essay article by Steve Chamberlain in The Hostta Journal (2010 Vol. 41 No. 1) makes comments about H. 'Deane's Dream', "Bob Solberg registered this cross between 'Blue Arrow' and 'Sea Fire' in 2000. It is a vigorous blue hosta in the garden. The light blue leaves hold their color well, at least until the plant blooms."
