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 Portulaca plant, botanically known as Portulaca oleracea and hereinafter referred to by the name ‘POR16000’.

The new Portulaca plant is a product of a planned breeding program conducted by the Inventor in Bozen, Italy. The objective of the breeding program is to create new heat-tolerant Portulaca plants with relatively short internodes and numerous attractive flowers.

The new Portulaca plant originated from a cross-pollination made by the Inventor in Bozen, Italy in May, 2015 of a proprietary selection of Portulaca oleracea identified as code number POR12005, not patented, as the female, or seed, parent with a proprietary selection of Portulaca oleracea identified as code number POR13109, 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 Bozen, Italy in June, 2016.

Asexual reproduction of the new Portulaca plant by vegetative terminal cuttings in a controlled greenhouse environment in Bozen, Italy since September, 2016, 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 ‘POR16000’. These characteristics in combination distinguish ‘POR16000’ as a new and distinct Portulaca plant:

• • 1. Compact, upright to outwardly spreading to eventually prostrate plant habit.
  • 2. Vigorous growth habit and rapid growth rate.
  • 3. Freely branching habit.
  • 4. Early and freely flowering habit.
  • 5. Long flowering period.
  • 6. Large dark red-colored flowers.
  • 7. 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 have shorter internodes than plants of the female parent selection.
  • 2. Plants of the new Portulaca flower earlier than plants of the female parent selection.
  • 3. 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 the following characteristics:

• • 1. Plants of the new Portulaca are more vigorous than plants of the male parent selection.
  • 2. Plants of the new Portulaca have dark red-colored flowers whereas plants of the male parent selection have yellow-colored flowers.

Plants of the new Portulaca can be compared to plants of the Portulaca oleracea ‘Pazzaz Deep Pink’, not patented. In side-by-side comparisons, plants of the new Portulaca differ primarily from plants of ‘Pazzaz Deep Pink’ in the following characteristics:

• • 1. Plants of the new Portulaca have larger flowers than plants of ‘Pazzaz Deep Pink’.
  • 2. Plants of the new Portulaca have dark red-colored flowers whereas plants of ‘Pazzaz Deep Pink’ have pink-colored flowers.

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.

At the top of the photographic sheet (FIG. 1) is a side perspective view of a typical flowering plant of ‘POR16000’ grown in a container and at the bottom of the photographic sheet is a close-up view of a typical flowering plant of ‘POR16000’.

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 Portulaca production. During the production of the plants, day temperatures averaged 33° C. and night temperatures averaged 15° C. Plants were pinched three weeks after planting and were twelve 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.
