Pelargonium plant named `Pactiopispl`

Abstract

A new and distinct interspecific Geranium plant named `Pactiopispl`, characterized by its broadly upright and mounding plant habit; vigorous growth habit; freely basal branching habit; dark green-colored leaves; early and freely flowering habit; and relatively large purplish pink-colored semi-double flowers with red-colored centers that are held above the foliar plane on strong peduncles.

Description

Botanical designation: Pelargonium x hortorum X Pelargonium peltatum.

Cultivar denomination: `PACTIOPISPL`.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of interspecific Geranium plant, botanically known as Pelargonium x hortorum X Pelargonium peltatum, and hereinafter referred to by the cultivar name `Pactiopispl`.

The new interspecific Geranium plant is a product of a planned breeding program conducted by the Inventor in Dresden, Germany. The objective of the breeding program is to develop new vigorous interspecific Geranium plants with dark colored leaves and bi-colored flowers.

The new interspecific Geranium plant originated from a cross-pollination made by the Inventor in Dresden, Germany during the summer of 2016 of an unidentified proprietary selection of Pelargonium x hortorum, not patented, as the female, or seed, parent with an unidentified proprietary selection of Pelargonium peltatum, not patented, as the male, or pollen, parent. Seed was collected from a number of potential parent plants, combined and sown. The new interspecific Geranium plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated mass cross-pollination in a controlled greenhouse environment in Dresden, Germany during the spring of 2017.

Asexual reproduction of the new interspecific Geranium plant by vegetative terminal cuttings in a controlled greenhouse environment in Dresden, Germany since January, 2018 has shown that the unique features of this new interspecific Geranium plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new interspecific Geranium 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 `Pactiopispl`. These characteristics in combination distinguish `Pactiopispl` as a new and distinct interspecific Geranium plant: 1. Broadly upright and mounding plant habit. 2. Vigorous growth habit. 3. Freely basal branching habit. 4. Dark green-colored leaves. 5. Early and freely flowering habit. 6. Relatively large purplish pink-colored semi-double flowers with red-colored centers that are held above the foliar plane on strong peduncles.

Plants of the new interspecific Geranium can be compared to plants of the Pelargonium x hortorum `Pactiohopispl`, disclosed in U.S. Plant patent application Ser. No. 16/873,687. In side-by-side comparisons, plants of the new interspecific Geranium differ from plants of `Pactiohopispl` in the following characteristics: 1. Flowers of plants of the new interspecific Geranium are semi-double types whereas flowers of plants of `Pactiohopispl` are single types. 2. Flowers of plants of the new interspecific Geranium are lighter purplish pink in color than flowers of plants of `Pactiohopispl`. 3. Plants of the new interspecific Geranium have somewhat shorter peduncles than plants of `Pactiohopispl`.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearance of the new interspecific Geranium plant 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 interspecific Geranium plant. The photograph comprises a side perspective view of a typical flowering plant of `Pactiopispl` grown in a container.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations, measurements and values describe plants grown in 19-cm containers during the spring, summer and autumn in a glass-covered greenhouse in Dresden, Germany and under cultural practices typical of commercial interspecific Geranium production.

Plants were four months old when the photograph was taken and nine months old when the detailed description was taken. In the detailed description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
