Claims
It is claimed:
1. A new and distinct Impatiens plant named `Dongimpetresta 19` as
illustrated and described.
Description
Botanical designation: Impatiens hawkeri.
Cultivar denomination: `DONGIMPETRESTA 19`.
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 `Dongimpetresta 19`.
The new Impatiens plant is a product of a planned breeding program
conducted by the Inventors in Koka, Ethiopia and Rheinberg,
Germany. The objective of the breeding program is to create new
early and freely flowering New Guinea Impatiens plants with large
attractive flowers and good garden performance.
The new Impatiens plant originated from a cross-pollination made by
the Inventors in November, 2012 in Koka, Ethiopia of a proprietary
selection of Impatiens hawkeri identified as code number
NN10-001649-001, not patented, as the female, or seed, parent with
a proprietary selection of Impatiens hawkeri identified as code
number NN09-006631-004, not patented, as the male, or pollen,
parent. The new Impatiens plant was discovered and selected by the
Inventors as a single flowering plant from within the progeny of
the stated cross-pollination in a controlled greenhouse environment
in Rheinberg, Germany in April, 2013.
Asexual reproduction of the new Impatiens plant by terminal
vegetative cuttings in a controlled greenhouse environment in
Rheinberg, Germany since June, 2013 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 `Dongimpetresta 19`.
These characteristics in combination distinguish `Dongimpetresta
19` as a new and distinct Impatiens plant: 1. Upright to outwardly
spreading and mounding plant habit. 2. Moderately vigorous growth
habit. 3. Freely branching habit. 4. Dark green-colored leaves. 5.
Freely and early flowering habit. 6. Medium to large bright red and
light purplish pink bi-colored flowers. 7. Good garden
performance.
Plants of the new Impatiens can be compared to plants of the female
parent selection. Plants of the new Impatiens differ primarily from
plants of the female parent selection in the following
characteristics: 1. Plants of the new Impatiens are more vigorous
than plants of the female parent selection. 2. Plants of the new
Impatiens have larger flowers than plants of the female parent
selection. 3. Flowers of plants of the new Impatiens are bright red
and light purplish pink in color whereas flowers of plants of the
female parent selection are dull red and light pink in color.
Plants of the new Impatiens can be compared to plants of the male
parent selection. Plants of the new Impatiens differ primarily from
plants of male parent selection in flower color as flowers of
plants of the new Impatiens are bright red and light purplish pink
in color whereas flowers of plants of the male parent selection are
red and dark pink in color.
Plants of the new Impatiens can be compared to plants of Impatiens
hawkeri `Dueptbus 14`, disclosed in U.S. Plant Pat. No. 26,780. In
side-by-side comparisons, plants of the new Impatiens differ
primarily from plants of `Dueptbus14` in the following
characteristics: 1. Plants of the new Impatiens are not as vigorous
as plants of `Dueptbus14`. 2. Plants of the new Impatiens have
larger flowers than plants of `Dueptbus14`. 3. Flowers of plants of
the new Impatiens are bright red and light purplish pink in color
whereas flowers of plants of `Dueptbus14` are bright red and red
purple in color.
Plants of the new Impatiens can be compared to plants of Impatiens
hawkeri `Duemagfi`, disclosed in U.S. Plant Pat. No. 23,912. In
side-by-side comparisons, plants of the new Impatiens differ
primarily from plants of `Duemagfi` in the following
characteristics: 1. Lower leaf surfaces of plants of the new
Impatiens are dark greyed purple in color whereas lower leaf
surfaces of plants of `Duemagfi` are dark green in color. 2. Plants
of the new Impatiens flower later than plants of `Duemagfi`. 3.
Plants of the new Impatiens have smaller flowers than plants of
`Duemagfi`. 4. Flowers of plants of the new Impatiens are bright
red and light purplish pink in color whereas flowers of plants of
`Duemagfi` are light red 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 is a side perspective view of a
typical flowering plant of `Dongimpetresta 19` grown in a
container.
The photograph on the second sheet is a close-up view of a typical
flowering plant of `Dongimpetresta 19`.
DETAILED BOTANICAL DESCRIPTION
The aforementioned photographs and following observations,
measurements and values describe plants grown during the winter and
early spring in 15.25-cm containers in a polyethylene-covered

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 16 weeks old when the
photographs and description were taken. In the following
