Ran Lydell of
Cooks Nursery and Eagle Bay Gardens in New York introduction, this
cultivar is a sport of H. 'Halcyon' which Ran registered in
1995. It is a medium size plant with shiny, smooth textured,
slightly wavy foliage that has thick substance. The pale bluish
lavender flowers bloom starting in late July.
An article about H. 'Canadian Shield', H. 'Devon Green', H. 'Peridot' and H.
'Valerie's Vanity' by Warren I. Pollock in
Hosta Journal (1997 Vol. 28 No. 1) states that, "These
four hostas are mutations of 'Halcyon', arguably the best of the late
Smith's blue-leaved Tardiana Group...Are all four cultivars the same? I haven't
seen any evidence they are different."
An article about the Halcyon Group by
Peter Cross in
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....Traditionally, sporting involves the cells in a section of a leaf
(either margin or center) changing color...These sports simply lack the wax
coating that makes the hosta leaves appear blue...I find it impossible to see
any differences between these green sports..." Cross lists the all-green sports
of 'Halcyon' including:
