This sport of H. 'Halcyon' was registered by
Peter Ruh of Ohio in 2005 on
behalf of the originator,
Roger and Ann Bowden of
England . The medium size
(18 inches high by 36 inches wide) plant has shiny, dark green
foliage with thick substance. It bears pale lavender flowers in
late July. This cultivar is part of the "Devon
Series" of hostas.
The Hostapedia by Mark Zilis (2009), "...appears identical to 'Valerie's Vanity', 'Canadian
Shield', and the other green leaved sports of 'Halcyon'."
The New Encyclopedia of Hostas by
Grenfell (2009) states: "Lovely in a cream stone container. Still the best-selling
green-leaved hosta in Europe...Purple-dotted, dark green scapes."
Warren I. Pollock in
Hosta Journal (1994 Vol. 25 No. 2) states "H.
'Devon Green', a sport of blue-leaved 'Halcyon', has dark green
leaves of the same distinct shape and characteristics as its parent.
The petioles are purple spotted...H. 'Peridot'
is a tissue culture sport of 'Halcyon' with dark-green, glossy
leaves, described as being a little smaller than those of
'Halcyon'...Are 'Peridot' and 'Devon Green' the same hosta or
sufficiently similar to be considered the same cultivar?...I'd like
to see side-by-side trials."
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."
Hosta Journal, (2002 Vol. 33 No. 2), "...'Halcyon',
'Devon Green' and 'June'...are the
same hosta but with different-colored leaves."
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:
An article by
Warren I. Pollack in
Hosta Journal (2020 Vol. 51 No. 1) titled
Doppelgänger Hostas: Fancy Name for
Look-alike Hostas, included a long list of hostas
which various hostaphiles, published articles or other sources have
indicated "look" the same. Some of these are, in fact, the same
plant with two or more different names. Others are hostas that vary
in some minor trait which is not immediately discernable to the
casual observer such as seasonal color variations, bloom traits, ploidy, etc. So, as Warren mentions, hostaphiles may differ as to the
plants listed but then, their opinions are based on visual observations and interpretations.
