A sport of H. 'Halcyon', this cultivar was registered by
Ken Knechtel of
Canada in 1993. It grows
into a medium size hosta about 14 inches high with a spread of
41 inches. The dark green foliage is shiny which differentiates
it from its mother plant. Pale bluish lavender flowers on 28
inch high scapes bloom from late July into August
followed by viable seeds.
The Hostapedia by Mark Zilis (2009), "...is no different from the several other named,
green-leaved 'Halcyon' sports."
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:
