Claims
It is claimed:
1. A new and distinct Poinsettia plant named `PER3112` as
illustrated and described.
Description
Botanical designation: Euphorbia pulcherrima Willd.
Cultivar denomination: `PER3112`.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of
Poinsettia plant, botanically known as Euphorbia pulcherrima
Willd., and hereinafter referred to by the cultivar name
`PER3112`.
The new Poinsettia plant is a product of a planned breeding program
conducted by the Inventor in Encinitas, Calif. The objective of the
breeding program is to create new uniform Poinsettia plants having
large inflorescences with attractive flower bracts and excellent
post-production longevity.
The new Poinsettia plant is a naturally-occurring whole plant
mutation of a proprietary selection of Euphorbia pulcherrima Willd.
identified as code number 7-10, not patented. The new Poinsettia
plant was discovered and selected by the Inventor from within a
population of plants of the mutation parent in a controlled
greenhouse environment in Encinitas, Calif. on Nov. 25, 2011.
Asexual reproduction of the new Poinsettia plant by terminal
vegetative cuttings in a controlled greenhouse environment in
Encinitas, Calif. since January, 2012 has shown that the unique
features of this new Poinsettia plant are stable and reproduced
true to type in successive generations of asexual reproduction.
SUMMARY OF THE INVENTION
Plants of the new Poinsettia 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, daylength 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 `PER3112`. These
characteristics in combination distinguish `PER3112` as a new and
distinct Poinsettia plant: 1. Compact, uniform, upright and mounded
plant habit. 2. Moderately vigorous growth habit. 3. Freely and
upright branching habit. 4. Dark green-colored leaves. 5. Under
natural season conditions, plants flower on or about November 7 in
Southern California. 6. Large inflorescences with creamy
white-colored flower bracts. 7. Good post-production longevity.
In side-by-side comparisons conducted in Encinitas, Calif., plants
of the new Poinsettia differ primarily from plants of the mutation
parent selection in flower bract color as plants of the mutation
parent selection have bright red-colored flower bracts with
pink-colored flecks.
Plants of the new Poinsettia can be compared to plants of the
Euphorbia pulcherrima Willd. `Peterstar White`, disclosed in U.S.
Plant Pat. No. 9,878. In side-by-side comparisons conducted in
Encinitas, Calif., plants of the new Poinsettia differed primarily
from plants of `Peterstar White` in the following characteristics:
1. Plants of the new Poinsettia were more compact than plants of
`Peterstar White`. 2. Plants of the new Poinsettia had a more
upright branching habit than plants of `Peterstar White`. 3. Plants
of the new Poinsettia had darker green-colored leaves than plants
of `Peterstar White`. 4. Plants of the new Poinsettia flowered
about 20 days earlier than plants of `Peterstar White`. 5. Plants
of the new Poinsettia and `Peterstar White` differed in flower
bract color as plants of `Peterstar White` had light lemon
white-colored flower bracts.
Plants of the new Poinsettia can be compared to plants of the
Euphorbia pulcherrima Willd. `PER10606`, disclosed in U.S. Plant
Pat. No. 20,351. In side-by-side comparisons conducted in
Encinitas, Calif., plants of the new Poinsettia differed primarily
from plants of `PER10606` in the following characteristics: 1.
Plants of the new Poinsettia were more compact than plants of
`PER10606`. 2. Plants of the new Poinsettia had a more upright
branching habit than plants of `PER10606`.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying photographs illustrate the overall appearance of
the new Poinsettia 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 Poinsettia plant.
The photograph on the first sheet is a side perspective view of a
typical flowering plant of `PER3112` grown in a container.
The photograph on the second sheet is a close-up view of a typical
flowering plant of `PER3112`.
DETAILED BOTANICAL DESCRIPTION
Plants used in the aforementioned photographs and in the following
detailed description were grown during the late autumn/early winter
in 16.5-cm containers in a polyethylene-covered greenhouse in
Encinitas, Calif. and under natural season conditions and cultural
practices typical of commercial Poinsettia production. During the
production of the plants, day temperatures averaged 26.degree. C.,
night temperatures averaged 18.degree. C. and light levels averaged
5,000 foot-candles. Measurements and numerical values represent
averages for typical flowering plants. Plants were pinched one time
and were 21 weeks old when the photographs and the 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.
