Claims
It is claimed:
1. A new and distinct Impatiens plant named `Doimmalaven` as
illustrated and described.
Description
Botanical designation: Impatiens hawkeri.
Cultivar denomination: `DOIMMALAVEN`.
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 `Doimmalaven`.
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, 2013 in Koka, Ethiopia of a proprietary
selection of Impatiens hawkeri identified as code number NN-0474,
not patented, as the female, or seed, parent with a proprietary
selection of Impatiens hawkeri identified as code number
NN11-003606-002, 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, 2014.
Asexual reproduction of the new Impatiens plant by terminal
vegetative cuttings in a controlled greenhouse environment in
Rheinberg, Germany since June, 2014 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 `Doimmalaven`. These
characteristics in combination distinguish `Doimmalaven` as a new
and distinct Impatiens plant: 1. Upright, 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. Relatively large purple to red
purple-colored flowers with white-colored centers. 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.
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 the male parent selection in the following
characteristics: 1. Plants of the new Impatiens are more vigorous
than plants of the male parent selection. 2. Plants of the new
Impatiens have larger flowers than plants of the male parent
selection. 3. Plants of the new Impatiens and the male parent
selection differ in flower color as plants of the male parent
selection have rose red and pinkish lavender bi-colored
flowers.
Plants of the new Impatiens can be compared to plants of Impatiens
hawkeri `Kialdan`, disclosed in U.S. Plant Pat. No. 14,029. In
side-by-side comparisons, plants of the new Impatiens differ
primarily from plants of `Kialdan` in the following
characteristics: 1. Plants of the new Impatiens have larger flowers
than plants of `Kialdan`. 2. Plants of the new Impatiens and
`Kialdan` differ in flower color as plants of `Kialdan` have light
purple-colored flowers with white-colored centers.
Plants of the new Impatiens can also be compared to plants of
Impatiens hawkeri `Duemagwis`, disclosed in U.S. Plant Pat. No.
26,782. In side-by-side comparisons, plants of the new Impatiens
differ primarily from plants of `Duemagwis` in the following
characteristics: 1. Plants of the new Impatiens have larger flowers
than plants of `Duemagwis`. 2. Plants of the new Impatiens and
`Duemagwis` differ in flower color as plants of `Duemagwis` have
light red-colored flowers.
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 at the bottom of the sheet comprises a side
perspective view of a typical flowering plant of `Doimmalaven`
grown in a container.
The photograph at the top of the sheet is a close-up view of a
typical flowering plant of `Doimmalaven`.
DETAILED BOTANICAL DESCRIPTION
The aforementioned photographs and following observations,
measurements and values describe plants grown during the winter 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 26.degree. C., night
temperatures averaged 18.degree. C. and light levels ranged from
4,500 to 5,500 lux. Plants were 25 weeks old when the photographs
and description were taken. In the following description, color
references are made to The Royal Horticultural Society Colour
Chart, 2007 Edition, except where general terms of ordinary
dictionary significance are used. Botanical classification:
