Description

Botanical designation: Euphorbia hypericifolia.
Cultivar denomination: ‘INCHADIACL’.
CROSS-REFERENCE TO A RELATED APPLICATION AND STATEMENT REGARDING PRIOR DISCLOSURES BY INVENTOR/APPLICANT
This application claims priority to a Canadian Plant Breeders' Rights application filed on Apr. 15, 2019, application number 19-9763. There have been no offers for sale anywhere in the world prior to the effective filing date of this Application and no accessibility to one of ordinary skill in the art could have been derived from the printed Plant Breeder's Rights documents.
The Inventor/Applicant asserts that no publications nor advertisements relating to sales, offers for sale or public distribution occurred more than one year prior to the effective filing date of this application. Any information about the claimed plant would have been obtained from a direct or indirect disclosure from the Inventor. Applicant claims a prior art exemption under 35 U.S.C. 102(b)(1) for disclosure and/or sales prior to the filing date but less than one year prior to the effective filing date.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Euphorbia plant, botanically known as Euphorbia hypericifolia and hereinafter referred to by the name ‘INCHADIACL’.
The new Euphorbia plant is a product of a planned breeding program conducted by the Inventor in Heidesheim, Germany. The objective of the program is to create and develop new freely branching Euphorbia plants with mounding plant habit and multiple white-colored flower bracts per inflorescence.
The new Euphorbia plant originated from a cross-pollination by the Inventor in September, 2014 of a proprietary selection of Euphorbia hypericifolia identified as code number Ch13-5000-13, not patented, as the female, or seed, parent with a proprietary selection of Euphorbia hypericifolia identified as code number Cha13-5020-2, not patented, as the male, or pollen, parent. The new Euphorbia plant was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination in a controlled greenhouse environment in Heidesheim, Germany in March, 2017.
Asexual reproduction of the new Euphorbia plant by terminal vegetative cuttings in a controlled greenhouse environment in Gensingen, Germany since March, 2017 has shown that the unique features of this new Euphorbia plant are stable and reproduced true to type in successive generations of asexual reproduction.
SUMMARY OF THE INVENTION
Plants of the new Euphorbia 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 ‘INCHADIACL’. These characteristics in combination distinguish ‘INCHADIACL’ as a new and distinct Euphorbia plant:
    • 1. Mounding to semi-trailing plant habit.
    • 2. Moderately vigorous growth habit.
    • 3. Freely branching habit.
    • 4. Freely flowering habit.
    • 5. Inflorescences with multiple white-colored flower bracts.
Plants of the new Euphorbia differ primarily from plants of the female parent selection in the following characteristics:
    • 1. Plants of the new Euphorbia are more mounding and denser than and not as upright and open as plants of the female parent selection.
    • 2. Plants of the new Euphorbia have broader leaves than plants of the female parent selection.
    • 3. Plants of the new Euphorbia have more flower bracts per inflorescence than plants of the female parent selection.
    • 2. Plants of the new Euphorbia and the female parent selection differ in flower bract color as plants of the female parent selection have grey-colored flower bracts.
Plants of the new Euphorbia differ primarily from plants of the male parent selection in the following characteristics:
    • 1. Plants of the new Euphorbia are more mounding and denser than and not as open as plants of the male parent selection.
    • 2. Plants of the new Euphorbia flower earlier than plants of the male parent selection.
    • 3. Plants of the new Euphorbia have pure white-colored flower bracts whereas plants of the male parent selection have greyish white-colored flower bracts.
Plants of the new Euphorbia can be compared to plants of the Euphorbia hypericifolia ‘Inneuphdia’, disclosed in U.S. Plant Pat. No. 17,567. In side-by-side comparisons, plants of the new Euphorbia differ primarily from plants of ‘Inneuphdia’ in inflorescence form as inflorescences of plants of the new Euphorbia have more flower bracts than inflorescences of plants of ‘Inneuphdia’.
Plants of the new Euphorbia can also be compared to plants of the Euphorbia hypericifolia ‘Ineupdidaz’, disclosed in U.S. Plant Pat. No. 26,848. In side-by-side comparisons, plants of the new Euphorbia differ primarily from plants of ‘Ineupdidaz’ in the following characteristics:
    • 1. Plants of the new Euphorbia are larger than plants of ‘Ineupdidaz’.
    • 2. Plants of the new Euphorbia are not as freely branching as plants of ‘Ineupdidaz’.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying colored photographs illustrate the overall appearance of the new Euphorbia 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 Euphorbia plant.
At the top of the photographic sheet is a side perspective view of a typical flowering plant of ‘INCHADIACL’ grown in a container and at the bottom of the photographic sheet is a close-up view of a typical flowering plant of ‘INCHADIACL’.
DETAILED BOTANICAL DESCRIPTION
The aforementioned photographs and following observations and measurements describe plants grown during the spring in 15.25-cm containers in a polyethylene-covered greenhouse in St. Thomas, Ontario, Canada and under cultural practices typical of commercial Euphorbia production. During the production of the plants, day temperatures averaged 27° C. and night temperatures averaged 15° C. Plants were eight weeks from planting rooted cuttings 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.
