Claims
What is claimed:
1. A new and distinct cultivar of double-flowered Impatiens
walleriana plant named `TiWhit`, as illustrated and described
herein.
Description
Latin name of the genus and species and variety denomination:
Impatiens walleriana plant and known by the cultivar name
`TiWhit`.
BACKGROUND--FIELD OF INVENTION
The present invention relates to a new and distinct cultivar
botanically known as `Impatiens walleriana` and by the cultivar
name `TiWhit`, which is shown in the photograph accompany this
specification.
The cultivar was developed and selected in a controlled breeding
program in a controlled environment in Broadbent, Oreg. by the
inventors, Harlan Cosner and Sue Cosner, as described herein. The
plants may be used in landscaping, window, and hanging baskets and
flower gardens. The plants are generally classed as an annual
bedding plant.
The accompanying photograph illustrates the overall appearance of
the new Impatiens. The photo shows the color as true as reasonably
possible to obtain in color reproductions of this type. Color in
the photograph may differ slightly from the color values cited in
the detailed botanical description which accurately described the
color of the new Impatiens.
BACKGROUND--DESCRIPTION OF THE PRIOR ART
The only known cultivar of relevant prior art is believed to be an
`Impatiens walleriana` named `Tioga White,` subject of U.S. Plant
Pat. No. 10,345.
COMPARISON
The impatiens plant of the present invention differs from prior
plants, namely `Tioga White` in at least the following ways: 1. The
flower color of `Tioga White` is white and remains white in warm
weather. The flower color of TiWhit is white but often takes on a
pink tinge in warm weather. 2. The plant of `TiWhit` is much larger
than plant of Tioga White. 3. The plant of `TiWhit` is a
double-flowered impatiens differing from its pollen parent in both
flower color and fertility. 4. `TiWhit` is a double-flowered
impatiens with reproductive organs replaced by sterile
petaloids.
These and other distinguishing characteristics will be apparent to
persons skilled in the art.
BACKGROUND--DISCOVERY AND PARENTAGE
The present cultivar was developed by standard cross-pollination.
The pollen producing parent was an unpatented double `Impatiens
walleriana` designated M-BR-39, and the seed producing parent was
an unpatented semi-double-flowered impatiens designated BR-D-1003.
The seed parent's flower color was white, and the pollen parent's
flower color was a blush white.
The cross was made in the breeders' controlled breeding program at
Broadbent, Oreg. The first asexual reproduction was also made at
Broadbent, Oreg. Successive asexual generations produced from
cuttings with two or more leaves have shown the cultivar to be
stable.
The cultivar is unique either in one or a combination of the
characteristics described herein. It is a new, complete
double-flowered `Impatiens walleriana` producing white flowers that
often show a light pink blush in temperatures warmer than
70.degree. F. minimums; dark green foliage; medium vigor; fully
double flowers held above or beyond the foliage on strong peduncles
and pedicels; and a mounded growth habit.
Color references are according to The Royal Horticultural Society
Colour Chart, except where general terms of ordinary dictionary
significance are used.
DETAILED DESCRIPTION
The following description relates to the following environmental
and cultural practices at Rogue River, Oreg., on or about Mar. 1,
2003.
The photograph illustrates the overall appearance of the cultivar
described herein.
The photograph was taken of a TiWhit plant of about 10 weeks of age
from rooted cuttings, at first inflorescence. There may be
variations between the colors in the photograph and the colors in
the following description due to light reflectance, or the amount
of blue or red light captured in the film. If such variations
occur, the written description shall control.
The plant of the present invention has not been observed in all
possible environmental and/or cultural conditions. The phenotype
may vary significantly with variations in environment such as
temperature, light level, humidity and also with cultural practices
such as fertility, soil, and water quality.
Container--6-inch Azalea containers.
Medium--Peat-lite type of soil less medium.
Greenhouse covering--Double layer Polyethylene with 50% shade
applied above the covering.
Minimum temperature--70.degree. F.
Maximum temperature--75.degree. F.
Light levels--1000 to 2000 ft candles.
Fertilizer--20-10-20 with trace elements applied twice followed by
one leaching with clear water.
Cutting type--Lateral stems with two or more leaves. Propagation:
Type of cutting.--Lateral stems with two or more leaves were used
for asexual reproduction. Time to initiate roots.--Generally about
7 to 10 days at soil temperature of 72.degree. F. Appearance and
form of mature plant: Plant form and habit.--Mounded and of medium
vigor. Plant size.--Plants mature at about 16 cm. in height and
about 30 cm. in width. Both of these measurements are a function of
age, environmental and cultural practices, and can vary
accordingly. Rooting description.--The roots are fibrous and
well-branched. Rooting ability.--Easy, no hormones needed.
Branching habit.--Plants are self-branching. Stems are strong and
freely produced. The number of stems depends upon cultural
practices, age of stems used as cuttings and the number of growth
buds present on the cutting when stuck. Stems.--Stems are freely
produced and no pinching to induce branching is needed. Color is
close to 144A. The stems at maturity are generally at least 3 mm in
diameter at the internodes, and the internode length is generally
at least 0.5 cm in length. Foliage shape and size.--Shape is ovate
with cuneate to attenuate base; crenate margin, margin having tiny
spines of an undeterminable greenish color, each being a less than
1 mm in length, and protruding perpendicularly outwards from the
leaf edge in direction and parallel with the leaf surfaces from
between the lobes of the crenate margin; and an acuminate apex.
Size of largest is about 3 cm long; about 3 cm wide. Foliage
color.--Adaxial surface close to137A; abaxial surface close to
147B; abaxial surface venation is close to 147B; adaxial surface
venation, main vein at base is closest to 144A, lateral veins are
barely distinguishable but appear closest to 137B. Foliage
texture.--Smooth and flat. Petioles.--Petioles are about 2 cm long,
half round, flat on upper surface which is about 2.5 mm wide, depth
of about 1 mm. Adaxial surface color appears to be between 146C and
146D but does easily not match any color in the chart; abaxial
surface color appears to be close to 146C to 146D. Natural
flowering season.--Year around in greenhouse conditions, and the
frost-free period from spring through fall when planted outdoors.
Flowers are produced continuously throughout the flowering season.
Bud size, shape & color.--The buds prior to opening are about 1
cm in length; about 0.75 cm in diameter; shape is ovate. Bud color
prior to opening is close to 142 B on top and close to 142C on
bottom. Time to flower.--Flowering begins at about 10 weeks form
rooted cuttings. Duration of flower.--Each flower generally lasts
about 5 days at 75.degree. F. maximum and 70.degree. F. minimum
temperature. Flowers borne.--Above or beyond the foliage. Flower
count.--Usually two or more open flowers per stem. Flower
texture.--Smooth and satiny. Flower fragrance.--None detected.
Flower color.--Petals/petaloids -- Adaxial surface is lighter than
155D but may show a pinkish overtone in high temperatures. Abaxial
surface is lighter than 155D. Flower size and shape.--Generally, at
least 3.5 cm wide; generally at least 1 cm deep. The above
measurements refer to the larger flowers, and the flower size was
taken during winter low light when the flowers are the smallest.
During spring and summer, the flowers are generally much larger
than the above measurements and as much as double the described
size. Petal size and shape.--The largest petals are generally at
least 1 cm. wide and at least 1.5 cm. deep; obovate to exaggerated
obovate in shape with obtuse to retuse apex, entire margin, and
cuneate to obtuse base. Petal count.--Generally about 25 or more.
Calyx.--Calyx consists of generally one sepal and one spur. The
spur is generally about 2 cm long, and about 2 mm in diameter at
sepal end; shape is an acicular tapering tube about 1 mm in
diameter at the sepal end, and it is attached toward the base of
the sepal in a peltate manner. Color is close to 145A in color. The
sepal generally measures about 0.75 cm wide, and about 1.25 cm
long; ovate in shape with anacute apex, entire margin, and obtuse
to cordate base; adaxial surface is lighter than 149D with a green
spot close to 142B where the spur connects; the abaxial surface is
lighter than 149D. Peduncles.--Generally at least 1.75 cm long;
about 2 mm in diameter; colored close to 144A. Good strength.
Pedicels.--Generally two or more per peduncle. Each is generally at
least 1.75 cm in length, and at least 1 mm in diameter. Color is
close to 144B but tends to be between 144A and 144B. Good strength.
Reproductive organs.--The reproductive organs are replaced with
sterile petaloids. Disease resistance.--Disease resistance has not
been tested. Dampness resistance.--The plant has shown a good
ability to hold the flowers in an outward manner during summer
rains. Cold/heat resistance.--Plant flowers well in summer
heat.
