Abstract

A new and distinct cultivar of Portulaca plant named ‘Pink Panther’, characterized by its outwardly spreading and trailing plant habit; freely branching growth habit; relatively rapid growth rate; double flower form; and pink-colored flowers.

Description

Botanical classification/cultivar designation: Portulaca grandiflora cultivar Pink Panther.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Portulaca plant, botanically known as Portulaca grandiflora, and hereinafter referred to by the name ‘Pink Panther’.

The new Portulaca is a product of a planned breeding program conducted by the Inventor in Naaldwijk, The Netherlands. The objective of the breeding program is to create new Portulacas with interesting flower forms and flower colors.

The new Portulaca is a naturally-occurring whole plant mutation of an unnamed selection of Portulaca grandiflora, not patented, that was discovered and selected by the Inventor during the summer of 2001 in a controlled environment in Naaldwijk, The Netherlands, on the basis of its pink-colored double flowers.

Asexual reproduction of the new cultivar by cuttings in a controlled environment in Naaldwijk, The Netherlands since 2001, has shown that the unique features of this new Portulaca are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the cultivar Pink Panther have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and culture such as temperature, light intensity, and daylength without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Pink Panther’. These characteristics in combination distinguish ‘Pink Panther’ as a new and distinct cultivar:

- 1. Outwardly spreading and trailing plant habit.
- 2. Freely branching growth habit.
- 3. Relatively rapid growth rate.
- 4. Double flower form.
- 5. Pink-colored flowers.

Plants of the parent selection differed primarily from plants of the new Portulaca in flower form and coloration as plants of the parent selection had single orange and yellow-colored flowers. In addition, plants of the new Portulaca is more vigorous than plants of the parent selection.

Plants of the new Portulaca can be compared to plants of the Portulaca cultivar Cindy, disclosed in U.S. Plant Pat. No. 13,605. In side-by-side comparisons conducted in Naaldwijk, The Netherlands, plants of the new Portulaca differed from plants of the cultivar Cindy primarily in flower coloration as plants of the cultivar Cindy had yellow and orange bi-colored flowers.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new cultivar, showing the colors as true as it is reasonably possible to obtain in colored reproduction 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.

The photograph at the top of the sheet comprises a side perspective view of a typical flowering plant of ‘Pink Panther’.

The photograph at the bottom of the sheet comprises a close-up view of a typical flower of ‘Pink Panther’.

DETAILED BOTANICAL DESCRIPTION

Plants used for the aforementioned photgraphs and following observations and measurements were planted into 15-cm containers and grown for about four months during the fall in a glass-covered greenhouse in Aalsmeer, The Netherlands. During the production of the plants, the day and night temperatures averaged 20° C.

In the following description, color reference are made to The Royal Horticultural Society Colour Chart, Edition 1995, except where general terms of ordinary dictionary significance are used.
