BACKGROUND OF THE INVENTION
·
The present invention relates to a new and distinct
cultivar of Hosta plant, botanically known as Hosta × 'Old Glory'.
·
The new cultivar was discovered by the inventor in
Waseca, Minnesota. United States of America, as a
naturally-occurring leaf mutation of the non-patented Hosta hybrid 'Glory' (unpatented), which is a hybrid of Hosta 'August Moon' (unpatented), and was observed in a
group of plants of the parent cultivar in 1996.
·
Asexual propagation of the new cultivar in 1999 at
Waseca, Minnesota., The United States of America, by division
and tissue culture has shown that the unique features of
this new Hosta plant are stable and reproduced true to
type in successive generations of asexual propagation.
·
BRIEF BRIEF SUMMARY OF THE INVENTION '
·
The following traits have been repeatedly observed and
are determined to be the unique characteristics of 'Old Glory'. These characteristics in combination distinguish
the new Hosta as a new and unique cultivar:
· 1. Medium size cordate leaves with a slightly rippled
leaf margin comprising a medium to large sized plant
mound;
·
2. Light yellow leaves maturing to darker yellow with an
uneven dark green margin; and
·
3. Clusters of lavender funnel-shaped flowers are
presented above the foliage in mid-summer.
·
The new Hosta can be compared to its parent cultivar, 'Glory'. In the new Hosta the leaves acquire a
variegation pattern wherein the leaves are substantially
light yellow with uneven dark green margins, whereas in
the parent 'Glory' as well as in the plant 'August Moon' the leaves have a fairly uniform yellow color.
·
The new Hosta cultivar has not been observed under all
possible environmental conditions. The phenotype may
vary to some extent with variations in environmental
conditions such as temperature and light intensity,
without any variance in genotype.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS
·
The accompanying colored photographs illustrate the
overall appearance of the new cultivar, showing the
colors as true as is reasonably possible to obtain in
colored reproductions of this type.
·
The first sheet of photographs comprises a top
perspective view of a typical plant of the new Hosta.
·
The second sheet of photographs comprises a top
perspective view of a typical plant of the new Hosta wherein the inflorescence including the flowers and
peduncles may also be seen.
·
The third sheet of photographs comprises a close-up view
of a typical leaf of the Hosta × 'Old Glory'.
·
Leaf and flower colors in the photographs may appear
differently from the actual colors due to light
reflectance.

DETAILED DESCRIPTION OF THE INVENTION
·
In the following description, color references are made
to The Royal Horticulture Society Colour Chart except
where general terms of ordinary dictionary significance
are used. The following observations and measurements
describe a three-year old plant, as depicted in the
accompanying color photographs, which was grown outdoors
in Waseca, Minnesota., United States of America.
·
Botanical Classification: Hosta × 'Old Glory'.
·
Parentage: Hosta × 'Glory'.
·
Propagation:
·
Method: By
division and tissue culture.
·
Plant description:
·
Plant shape: Mounding,
dome-shaped, symmetrical.
·
Growth habit: Initially
upright when young, with leaves outwardly arching as
they mature.
·
Culture: Light
to medium shade in moist soil.
·
Plant type: Herbaceous
perennial.
·
Plant height: About
14 inches from soil level to top of leaf plane.
·
Plant diameter: About
36 inches.
·
Vigor and growth rate: Moderate
to high.
·
Disease resistance: No
known particular resistance or susceptibility to disease
known to Hosta observed.
·
Foliage description:
·
Leaf shape: Cordate
with slight ripple of outer leaf margin.
·
Leaf margin: Entire.
·
Leaf texture: Leaves
are fairly smooth with the exception of ridges formed by
the leaf veins.
·
Leaf size: Length:
About 8.5 inches. Width: About 7.5 inches.
·
Venation pattern: Campylodrome
with 10 pairs of veins.
·
Leaf color: Centers:
Emerge in yellow-green (about 145D) maturing to yellow
(11C) by early to mid-summer. Margins: Green (about
131C), margins being ¾ of an inch to 2 inches wide.
·
Petioles description: In a mature plant petioles may
have a length of approximately 25-30 centimeters in and
a diameter of about 1.0 cm (0.4 in.) . Petiole color is yellow-green.
·
Flower description:
·
Bloom period: Mid-summer.
·
Fragrance: No
observed fragrance.
·
Flower arrangement: Raceme
comprised of numerous single flowers having six tepals.
Each inflorescence having around 25 flowers, with each
flower lasting approximately 1 day.
·
Flower shape: Funnel-shaped.
·
Flower size: Approximately
4.5-5 cm.
·
Flower color: Lavender
(85D).
·
Scape description:
·
Number: The
number of scapes per plant is dependent on the maturity
of the plant. Each mature eye comprising the clump may
produce a flower scape under normal growing conditions.
The scape has a color approximately the same as that the
leaf interior. The length of the scape may be up to and
about 25 inches in a mature plant with a diameter of
about 0.5 to 1.0 cm (0.4 in.) and having a round shape and smooth
texture.
·
Description of Reproductive organs: The reproductive
organs comprise six stamens and a compound ovary having
three locules. The size of the anther is Approximately 0.5 cm (0.2 in.) with a color of 11A. The pollen is average in
abundance. The stigma is a three lobed stigma of color
155C, and the style has a color of 155A.
·
Seed development: Has not been observed.
·
Root development: From transfer to rooting media in
tissue culture, rooting takes approximately 4 weeks at
about 68 degrees Fahrenheit. After transfer from stage
III in tissue culture to planting into soil in a green
house, a well rooted plant is produced in approximately
8 weeks with a day time temperature of about 68 degrees
Fahrenheit (about 65 degrees Fahrenheit at night) and a
soil temperature of about 78 degrees Fahrenheit. |
