This cultivar which is a sport of H. 'Halcyon' was originated by Sandra Bond of Goldbrook Plants in England and it was registered on her behalf in 2009 by Kevin Walek (Hosta Registrar). The mound grows to a medium size about 16 inches in height and 45 inches in spread. The leaves are broadly ovate, very slightly wavy and are not corrugated. In the center, a light green coloration is present. It bears pale bluish lavender flowers from mid-July into August.

An article in The Hosta Journal (2004 Vol. 35 No. 2) states that this was the first sport of H. 'Halcyon'.

An article about the Halcyon Group by Peter Cross in The Hosta Journal (2004 Vol. 35 No.2) says, "...'Halcyon' is a first-generation member (TF 1 × 7) of the legendary Tardiana Group of hostas, which consists of hybrids of 'Tardiflora' × H. 'Elegans', produced in England by Eric Smith,  the master hybridizer of blue hostas, in the 1960s....The first sport...was aptly named 'Goldbrook Glimmer', discovered by Sandra Bond of Goldbrook Plants in England...features a narrow "glimmer" or blaze of green down the middle of the blue leaves...The variegation is most pronounced in cooler climates and early in the season...In especially warm climates, the mound will appear a solid blue by the end of the summer."
