This
cultivar forms a medium size (16 inches high by 41 inches wide) mound of corrugated,
thick textured foliage and near white flowers from late June into July. The flowers have a pale lavender stripe in the middle of
the petals. It is a slow growing cultivar that was registered in
1984 by
The American Hosta Society.
H. 'Gold Medallion' is a sport of
H. 'Tokudama
Aureonebulosa' that was found in
tissue culture production.
The Hostapedia by Mark Zilis (2009), states that this cultivar "...has been around for
many years under an assortment of names including H. tokudama
'Golden' and 'Golden Tokudama'. Both of those names have also
been used for the very, very similar 'Golden
Bullion'."
The New Encyclopedia of Hostas by
Diana
Grenfell (2009) states: "Group name embracing all yellow-leaved natural
sports of H. 'Tokudama'...Site in light to
medium shade all day, otherwise the edges can scorch. Among the first
yellow-leaved hostas introduced. Now largely superseded by gold-leaved hostas
which do not scorch."
Nomenclature changes recommended in the
1991 book The
Genus Hosta by
W. George Schmid and accepted by The American Hosta Society would update names as follows: H. tokudama is now H. 'Tokudama'.
"Plant
is a yellow sport of H. 'Tokudama Aureonebulosa'.
Several clones exist and form the H. 'Tokudama
Aureonebulosa Yellow' group. This clonal cultivar name
has been assigned and is horticulturally used for all
yellow-leaved members of the H. 'Tokudama Aureonebulosa'
group but this is technically incorrect because several
distinct forms of the latter exist. I have established a
H. 'Tokudama Aureonebulosa Yellow' group...under which
all the distinct yellow taxa in this group can be
assembled in a broad sense and named."
An article by
Marvin C. Eisel, Hosta Registrar in
The
Hosta Journal (1985 Vol. 16) states that, "In the Fall
1984 The American Hosta
Society Newsletter, page 12, I reported that I had registered in the name of
The American Hosta
Society, the cultivar name 'Golden Sunburst' for the golden forms
of H. '
Frances Williams' and 'Golden Medallion' for all the golden
mutations of H. tokudama."
