Claims
It is claimed:
1. A new and distinct Oleander plant named `ATXNOKHP` as
illustrated and described.
Description
Botanical designation: Nerium oleander.
Cultivar denomination: `ATXNOKHP`.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of
Oleander plant, botanically known as Nerium oleander and
hereinafter referred to by the name `AUCNOKHP`.
The new Oleander plant is a product of a planned breeding program
conducted by the Inventor in Austin, Tex. The objective of the
breeding program is to create new compact Oleander plants with
uniform plant habit, freely branching habit and numerous attractive
flowers.
The new Oleander plant originated from an open-pollination in 2010
in Austin, Tex. of an unnamed selection of Nerium oleander, not
patented, as the female, or seed, parent with an unknown selection
of Nerium oleander as the male, or pollen, parent. The new Oleander
plant was discovered and selected by the Inventor as a single
flowering plant from within the progeny of the stated
open-pollination in a controlled outdoor nursery in Austin, Tex. in
May, 2014.
Asexual reproduction ofthe new Oleander plant by softwood stem
cuttings propagated in a controlled greenhouse environment in Grand
Haven, Mich. since May, 2014 has shown that the unique features of
this new Oleander plant are stable and reproduced true to type in
successive generations of asexual reproduction.
SUMMARY OF THE INVENTION
Plants of the new Oleander 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 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 `ATXNOKHP`. These
characteristics in combination distinguish `ATXNOKHP` as a new and
distinct Oleander plant: 1. Relatively compact, upright to somewhat
outwardly spreading plant habit. 2. Freely branching habit. 3. Dark
green-colored leaves. 4. Freely flowering habit. 5. Dark red
purple-colored flowers. 6. Good garden performance.
Plants of the new Oleander differ from plants of the female parent
selection in the following characteristics: 1. Plants of the new
Oleander are more freely branching than plants of the female parent
selection. 2. Flowers of plants of the new Oleander are darker red
purple in color than flowers of plants of the female parent
selection.
Plants of the new Oleander can be compared to plants of Nerium
oleander `Hardy Red`, not patented. In side-by-side comparisons,
plants of the new Oleander differ from plants of `Hardy Red` in the
following characteristics: 1. Plants of the new Oleander are more
compact than plants of `Hardy Red`. 2. Plants of the new Oleander
have dark red purple-colored flowers whereas plants of `Hardy Red`
have red-colored flowers.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying photographs illustrate the overall appearance of
the new Oleander 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 Oleander plant.
The photograph on the first sheet (FIG. 1 of 2) comprises a side
perspective view of a typical flowering plant of `ATXNOKHP` grown
in an outdoor nursery in Austin, Tex.; the plant used in the
photograph was four years old.
The photograph on the second sheet (FIG. 2 of 2) is a close-up view
of typical flowers of `ATXNOKHP` of a plant grown in a
polyethylene-covered greenhouse environment in Grand Haven, Mich.;
the plant used in the photograph was two years old.
DETAILED BOTANICAL DESCRIPTION
Plants used for the following observations and measurements were
grown during the summer in three-gallon containers in a
polyethylene-covered greenhouse in Grand Haven, Mich. Plants were
grown under cultural practices typical of commercial Juniper plant
production. During the production of the plants, day temperatures
ranged from 18.degree. C. to 27.degree. C. and night temperatures
ranged from 5.degree. C. to 10.degree. C. Plants were two years old
when the description was 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: Nerium
