Description

Botanical designation: Kalanchoe blossfeldiana.

Cultivar denomination: ‘DOKALGLOSS’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct Kalanchoe plant, botanically known as Kalanchoe blossfeldiana and hereinafter referred to by the name ‘Dokalgloss’.

The new Kalanchoe is a product of a planned breeding program conducted by the Inventor in De Lier, The Netherlands. The objective of the breeding program is to create new freely-branching and freely-flowering Kalanchoe plants with attractive leaf and flower coloration.

The new Kalanchoe plant originated from a cross-pollination made by the Inventor in De Lier, The Netherlands in April, 2014 of a proprietary selection of Kalanchoe blossfeldiana identified as code number 082242-02, not patented, as the female, or seed, parent with a proprietary selection of Kalanchoe blossfeldiana identified as code number 5353-01, not patented, as the male, or pollen, parent. The new Kalanchoe plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination in a controlled environment in De Lier, The Netherlands in March, 2015.

Asexual reproduction of the new Kalanchoe plant by vegetative terminal cuttings in a controlled environment in De Lier, The Netherlands since 2015 has shown that the unique features of this new Kalanchoe plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Kalanchoe 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, daylength 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 ‘Dokalgloss’. These characteristics in combination distinguish ‘Dokalgloss’ as a new and distinct Kalanchoe plant:

    • 1. Relatively compact, upright and uniformly mounded plant habit.
    • 2. Moderately vigorous growth habit.
    • 3. Freely branching plant habit.
    • 4. Glossy dark green-colored leaves.
    • 5. Uniform, early and freely flowering habit.
    • 6. Large red purple and light red purple bi-colored flowers.
    • 7. Excellent postproduction longevity.

Plants of the new Kalanchoe can be compared to plants of the female parent selection. Plants of the new Kalanchoe differ from plants of the female parent selection in the following characteristics:

    • 1. Plants of the new Kalanchoe are larger and more vigorous than plants of the female parent selection.
    • 2. Plants of the new Kalanchoe are more freely branching than plants of the female parent selection.
    • 3. Flowers of plants of the new Kalanchoe are slightly smaller than flowers of plants of the female parent selection.

Plants of the new Kalanchoe can be compared to plants of the male parent selection. Plants of the new Kalanchoe differ from plants of the male parent selection in the following characteristics:

    • 1. Plants of the new Kalanchoe are larger than plants of the male parent selection.
    • 2. Flowers of plants of the new Kalanchoe are larger than flowers of plants of the male parent selection.
    • 3. Plants of the new Kalanchoe and the male parent selection differ in flower color as plants of the new Kalanchoe have red purple and light red purple bi-colored flowers whereas plants of the male parent selection have red-colored flowers.

Plants of the new Kalanchoe can be compared to plants of the Kalanchoe blossfeldiana ‘Fikalpitonpi’, disclosed in U.S. Plant Pat. No. 27,911. In side-by-side comparisons, plants of the new Kalanchoe differ primarily from plants of ‘Fikalpitonpi’ in the following characteristics:

    • 1. Plants of the new Kalanchoe are more freely branching than plants of ‘Fikalpitonpi’.
    • 2. Plants of the new Kalanchoe flower earlier than plants of ‘Fikalpitonpi’.
    • 3. Plants of the new Kalanchoe have slightly larger flowers than plants of ‘Fikalpitonpi’.
    • 4. Plants of the new Kalanchoe and ‘Fikalpitonpi’ differ in flower color as flowers of plants of ‘Fikalpitonpi’ are lighter in color than flowers of the new Kalanchoe.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Kalanchoe 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 Kalanchoe plant.

The photograph on the first sheet (FIG. 1 of 2) is a side perspective view of a typical flowering plant of ‘Dokalgloss’ grown in a container.

The photograph on the second sheet (FIG. 2 of 2) is a close-up view of a typical open flower and flower buds of ‘Dokalgloss’.

 DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown during the autumn in 10-cm containers in a glass-covered greenhouse in De Lier, The Netherlands and under cultural practices typical of commercial Kalanchoe production. During the production of the plants, day temperatures ranged from 18° C. to 20° C., night temperatures averaged 18° C. and light levels ranged from 10,000 lux to 50,000 lux. Plants received long day/short night conditions (more than 14 hours of light) for three weeks then plants received photoinductive short day/long night conditions (minimum 14 hours darkness) until flowering. Plants were eleven weeks old when the photographs were taken and twelve weeks old when the description was taken. In the detailed description, color references are made to The Royal Horticultural Society Colour Chart, 2007 Edition, except where general terms of ordinary dictionary significance are used.
