Poinsettia plant named ‘Duepremimice’

Abstract

A new and distinct cultivar of Poinsettia plant named ‘Duepremimice’, characterized by its compact, upright and outwardly spreading plant habit; freely branching habit; early flowering habit; inflorescences with pale yellow and red bi-colored flower bracts; and excellent post-production longevity.

Description

Botanical designation: Euphorbia pulcherrima Willd.

Cultivar denomination: ‘Duepremimice’.

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 name ‘Duepremimice’.

The new Poinsettia plant is a naturally-occurring whole plant mutation of a proprietary selection of Euphorbia pulcherrima Willd. identified as code number E-16-18, not patented. The new Poinsettia was discovered and selected by the Inventor as a single flowering plant within a population of plants of the parent selection in a controlled greenhouse environment in Rheinberg, Germany on Nov. 1, 2008.

Asexual reproduction of the new Poinsettia plant by terminal vegetative cuttings in a controlled greenhouse environment in Rheinberg, Germany since June, 2009, 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 environmental conditions. The phenotype may vary somewhat with variations in environment 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 ‘Duepremimice’. These characteristics in combination distinguish ‘Duepremimice’ as a new and distinct cultivar of Poinsettia:

• • 1. Compact, upright and outwardly spreading plant habit.
  • 2. Freely branching habit.
  • 3. Early flowering habit.
  • 4. Inflorescences with pale yellow and red bi-colored flower bracts.
  • 5. Excellent post-production longevity.

Plants of the new Poinsettia differ primarily from plants of the parent selection in flower bract coloration as plants of the parent selection have red-colored flower bracts.

Plants of the new Poinsettia differ primarily from plants of ‘Duepremimpol’, disclosed in a U.S. Plant patent application No. 12/586,299, in flower bract color as plants of ‘Duepremimpol’ have pale yellow-colored flower bracts.

Plants of the new Poinsettia can also be compared to plants of Euphorbia pulcherrima Willd. ‘Ice Punch’, disclosed in U.S. Plant Pat. No. 19,504. In side-by-side comparisons conducted in Rheinberg, Germany, plants of the new Poinsettia differed from plants of ‘Ice Punch’ in the following characteristics:

• • 1. Plants of the new Poinsettia were more compact than plants of ‘Ice Punch’.
  • 2. Plants of the new Poinsettia were more freely branching than plants of ‘Ice Punch’.
  • 3. Plants of the new Poinsettia had shorter internodes than plants of ‘Ice Punch’.
  • 4. Plants of the new Poinsettia flowered earlier than plants of ‘Ice Punch’.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph illustrates the overall appearance of the new Poinsettia plant. The photograph shows the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph 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 comprises a side perspective view of a typical flowering plant of ‘Duepremimice’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations and measurements describe plants grown in Rheinberg, Germany during the winter in a glass-covered greenhouse and under conditions and practices which approximate those generally used in commercial Poinsettia production. During the production of the plants, day and night temperatures averaged 22° C. and light levels were about 4,500 lux. Measurements and numerical values represent averages for typical flowering plants. Single plants were grown in 13-cm containers and were pinched one time five weeks after planting the cuttings. Plants were 16 weeks from planting when the photograph and the detailed description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
