Claims
It is claimed:
1. A new and distinct Impatiens plant named `Dongwiroblupi 20` as
illustrated and described.
Description
Botanical designation: Impatiens hawkeri.
Cultivar denomination: `DONGIWIROBLUPI 20`.
STATEMENT REGARDING PRIOR DISCLOSURES BY INVENTOR &
APPLICANT/ASSIGNEE
An European Community Plant Breeder's Rights application for the
instant plant was filed by the Applicant/Assignee, Dummen Group
B.V. of De Lier, The Netherlands on Oct. 29, 2020, application
number 2020/2732. Foreign priority is not claimed to this
application.
The Inventor and Applicant/Assignee assert that no publications nor
advertisements relating to sales, offers for sale or public
distribution occurred more than one year prior to the effective
filing date of this application. Any information about the claimed
plant would have been obtained from a direct or indirect disclosure
from the Inventor and/or Applicant/Assignee. Inventor and
Applicant/Assignee claim a prior art exception under 35 U.S.C.
102(b)(1) for disclosure and/or sales prior to the filing date but
less than one year prior to the effective filing date.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of New
Guinea Impatiens plant, botanically known as Impatiens hawkeri and
hereinafter referred to by the name `Dongwiroblupi 20`.
The new Impatiens plant is a product of a planned breeding program
conducted by the Inventor in Koka, Ethiopia and Encinitas, Calif.
The objective of the breeding program is to create new freely
branching and early and freely flowering New Guinea Impatiens
plants with attractive double flowers and good garden
performance.
The new Impatiens plant originated from a self-pollination made by
the Inventor in November, 2016 in Koka, Ethiopia of Impatiens
hawkeri `Duewildrltpi`, disclosed in U.S. Plant Pat. No. 30,746.
The new Impatiens plant was discovered and selected by the Inventor
as a single flowering plant from within the progeny of the stated
self-pollination in a controlled greenhouse environment in
Encinitas, Calif. in April, 2017.
Asexual reproduction of the new Impatiens plant by terminal
vegetative cuttings in a controlled greenhouse environment in
Rheinberg, Germany since June, 2017 has shown that the unique
features of this new Impatiens plant are stable and reproduced true
to type in successive generations.
SUMMARY OF THE INVENTION
Plants of the new Impatiens have not been observed under all
possible combinations of environmental conditions and cultural
practices. The phenotype may vary somewhat with variations in
environmental conditions such as temperature, daylight and light
intensity without, however, any variance in genotype.
The following traits have been repeatedly observed and are
determined to be the unique characteristics of `Dongwiroblupi 20`.
These characteristics in combination distinguish `Dongwiroblupi 20`
as a new and distinct Impatiens plant: 1. Upright to somewhat
outwardly spreading and uniformly mounding plant habit. 2.
Moderately vigorous growth habit. 3. Freely branching habit. 4.
Glossy dark green-colored leaves. 5. Freely flowering habit. 6.
Semi-double flowers that are blush pink in color. 7. Good garden
performance.
Plants of the new Impatiens can be compared to plants of the
parent, `Duewildrltpi`. Plants of the new Impatiens differ
primarily from plants of `Duewildrltpi` in the following
characteristics: 1. Plants of the new Impatiens are more compact
than plants of `Duewildrltpi`. 2. Plants of the new Impatiens are
more freely branching than plants of `Duewildrltpi`. 3. Flowers of
plants of the new Impatiens have a more intense pink blush than
flowers of plants of `Duewildrltpi`.
Plants of the new Impatiens can be compared to plants of Impatiens
hawkeri `Doimwirored`, disclosed in U.S. Plant Pat. No. 31,564. In
side-by-side comparisons, plants of the new Impatiens differ
primarily from plants of `Doimwirored` in the following
characteristics: 1. Plants of the new Impatiens have smaller
flowers than plants of `Doimwirored`. 2. Flowers of plants of the
new Impatiens are blush pink in color whereas flowers of plants of
`Doimwirored` are dark red in color.
Plants of the new Impatiens can also be compared to plants of
Impatiens hawkeri `Moorea`, disclosed in U.S. Plant Pat. No. 9,147.
In side-by-side comparisons, plants of the new Impatiens differ
primarily from plants of `Moorea` in the following characteristics:
1. Plants of the new Impatiens are more vigorous than plants of
`Moorea`. 2. Plants of the new Impatiens have semi-double flowers
whereas plants of `Moorea` have single flowers. 3. Flowers of
plants of the new Impatiens are blush pink in color whereas flowers
of plants of `Moorea` are white in color.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying colored photographs illustrate the overall
appearance of the new Impatiens plant showing the colors as true as
it is reasonably possible to obtain in colored reproductions of
this type. Colors in the photographs may differ slightly from the
color values cited in the detailed botanical description which
accurately describe the colors of the new Impatiens plant.
The photograph on the first sheet (FIG. 1) is a side perspective
view of a typical flowering plant of `Dongwiroblupi 20` grown in a
container.
The photograph on the second sheet (FIG. 2) is a close-up view of a
typical flowering plant of `Dongwiroblupi 20`.
DETAILED BOTANICAL DESCRIPTION
The aforementioned photographs and following observations,
measurements and values describe plants grown during the summer in
16.5-cm containers in a polyethylene-covered greenhouse in
Encinitas, Calif. and under cultural practices typical of
commercial New Guinea Impatiens production. During the production
of the plants, day temperatures averaged 25.degree. C., night
temperatures averaged 20.degree. C. and light levels ranged from
4,000 to 4,500 lux. Plants were 14 weeks old when the photographs
and description were taken. In the following description, color
references are made to The Royal Horticultural Society Colour
Chart, 2015 Edition, except where general terms of ordinary
dictionary significance are used. Botanical classification:
