Abstract

A new and distinct cultivar of Euphorbia plant named ‘Duestawhifla’, characterized by its compact, upright, outwardly spreading and mounding plant habit; moderately vigorous growth habit; freely branching habit; and numerous white-colored flowers.

Description

Botanical designation: Chamaesyce hypericifolia.
Cultivar denomination: ‘DUESTAWHIFLA’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Euphorbia plant, botanically known as Chamaesyce hypericifolia and hereinafter referred to by the name ‘Duestawhifla’.
The new Euphorbia plant is a product of a planned breeding program conducted by the Inventor in Rheinberg, Germany. The objective of the breeding program is to create new compact Euphorbia plants with freely branching and flowering habit.
The new Euphorbia plant originated from an open-pollination in July, 2009 in Rheinberg, Germany of a proprietary selection of Chamaesyce hypericifolia identified as code number F-02-02, not patented, as the female, or seed, parent with an unknown selection of Chamaesyce hypericifolia as the male, or pollen, parent. The new Euphorbia 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 greenhouse environment in Rheinberg, Germany in May, 2011.
Asexual reproduction of the new Euphorbia plant by vegetative cuttings in a controlled greenhouse environment in Rheinberg, Germany since July, 2011 has shown that the unique features of this new Euphorbia plant are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
Plants of the new Euphorbia have not been observed under all possible 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 ‘Duestawhifla’. These characteristics in combination distinguish ‘Duestawhifla’ as a new and distinct Euphorbia plant:
    • 1. Compact, upright, outwardly spreading and mounding plant habit.
    • 2. Moderately vigorous growth habit.
    • 3. Freely branching habit.
    • 4. Numerous white-colored flowers.
The new Euphorbia can be compared to plants of the female parent selection. Plants of the new Euphorbia differ primarily from plants of the female parent selection in leaf color as plants of the new Euphorbia have lighter green-colored leaves than plants of the female parent selection.
Plants of the new Euphorbia can also be compared to plants of Euphorbia ‘Inneuphdia’, disclosed in U.S. Plant Pat. No. 17,567. In side-by-side comparisons, plants of the new Euphorbia differed from plants of ‘Inneuphdia’ in the following characteristics:
    • 1. Plants of the new Euphorbia were more compact than plants of ‘Inneuphdia’.
    • 2. Plants of the new Euphorbia had shorter internodes than plants of ‘Inneuphdia’.
    • 3. Plants of the new Euphorbia had larger leaves than plants of ‘Inneuphdia’.
    • 4. Plants of the new Euphorbia had larger flowers than plants of ‘Inneuphdia’.
BRIEF DESCRIPTION OF THE PHOTOGRAPH
The accompanying colored photograph illustrates the overall appearance of the new Euphorbia showing 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 Euphorbia plant.
The photograph is a side perspective view of a typical flowering plant of ‘Duestawhifla’ grown in a container.
 DETAILED BOTANICAL DESCRIPTION
The aforementioned photograph and following observations, measurements and values describe plants grown during the summer in 12-cm containers in a glass-covered greenhouse in Rheinberg, Germany and under cultural practices typical of commercial Euphorbia production. During the production of the plants, day and night temperatures averaged 22° C. and light levels averaged 4,500 lux. Plants were pinched one time three weeks after planting and were 16 weeks old when the photograph and 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.
