Abstract

A new and distinct cultivar of Portulaca plant named ‘Doportcupcocon’, characterized by its compact and spreading to prostrate growth habit; vigorous growth habit; freely branching habit; freely flowering habit; large white-colored flowers; and good garden performance.

Description

Botanical designation: Portulaca hybrida.
Cultivar denomination: ‘DOPORTCUPCOCON’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Portulaca plant, botanically known as Portulaca hybrida and hereinafter referred to by the name ‘Doportcupcocon’.
The new Portulaca 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 spreading Portulaca plants with numerous large and attractive flowers.
The new Portulaca plant originated from a cross-pollination made by the Inventor in Rheinberg, Germany in July, 2016 of a proprietary selection of Portulaca hybrida identified as code number RR13-001015-001, not patented, as the female, or seed, parent with a proprietary selection of Portulaca hybrida identified as code number RR15-001110-002, not patented, as the male, or pollen, parent. The new Portulaca plant was discovered and selected by the Inventor as a flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in Rheinberg, Germany in May, 2018.
Asexual reproduction of the new Portulaca plant by vegetative terminal cuttings in a controlled greenhouse environment in Rheinberg, Germany since June, 2018, has shown that the unique features of this new Portulaca plant are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
Plants of the new Portulaca 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 ‘Doportcupcocon’. These characteristics in combination distinguish ‘Doportcupcocon’ as a new and distinct Portulaca plant:
    • 1. Compact and spreading to prostrate growth habit.
    • 2. Vigorous growth habit.
    • 3. Freely branching habit.
    • 4. Freely flowering habit.
    • 5. Large white-colored flowers.
    • 6. Good garden performance.
Plants of the new Portulaca can be compared to plants of the female parent selection. Plants of the new Portulaca differ primarily from plants of the female parent selection in the following characteristics:
    • 1. Plants of the new Portulaca flower earlier than plants of the female parent selection.
    • 2. Plants of the new Portulaca have larger flowers than plants of the female parent selection.
Plants of the new Portulaca can be compared to plants of the male parent selection. Plants of the new Portulaca differ primarily from plants of the male parent selection in flower color as plants of the new Portulaca have white-colored flowers whereas plants of the male parent selection have creamy white-colored flowers.
Plants of the new Portulaca also can be compared to plants of the Portulaca hybrida ‘Duna White’, not patented. In side-by-side comparisons, plants of the new Portulaca differ primarily from plants of ‘Duna White’ in the following characteristics:
    • 1. Plants of the new Portulaca are more compact than plants of ‘Duna White’.
    • 2. Plants of the new Portulaca have lighter green-colored leaves than plants of ‘Duna White’.
    • 3. Flowers of plants of the new Portulaca have more stamens than flowers of plants of ‘Duna White’.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying colored photographs illustrate the overall appearance of the new Portulaca 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 Portulaca plant.
The photograph on the first sheet (FIG. 1 of 2) is a side perspective view of a typical flowering plant of ‘Doportcupcocon’ grown in a container.
The photograph on the second sheet (FIG. 2 of 2) is a close-up view of a typical flowering plant of ‘Doportcupcocon’.
 DETAILED BOTANICAL DESCRIPTION
The aforementioned photographs and following observations, measurements and values describe plants grown during the spring and summer in 13-cm containers in a glass-covered greenhouse in Rheinberg, Germany and under cultural practices typical of commercial Portulaca production. During the production of the plants, day and night temperatures averaged 18° C. and light levels averaged 1,500 lux. Plants were pinched one time three weeks after planting and were twelve weeks old when the photographs and the description were taken. In the description, color references are made to The Royal Horticultural Society Colour Chart, Fifth Edition, except where general terms of ordinary dictionary significance are used.
