Abstract

A new and distinct cultivar of Mandevilla plant named ‘Inmanburg’, characterized by its upright and vining plant habit; moderately vigorous growth habit; freely branching habit; moderately glossy dark green-colored leaves; freely flowering habit; dark red to greyed purple-colored flowers with greyed orange-colored centers; and relative tolerance to low temperatures.

Description

Botanical designation: Mandevilla sanderi.

Cultivar denomination: ‘INMANBURG’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Mandevilla plant, botanically known as Mandevilla sanderi and hereinafter referred to by the name ‘Inmanburg’.

The new Mandevilla plant is a product of a planned breeding program conducted by the Inventor in Johannesburg, South Africa and Heidesheim, Germany. The objective of the breeding program is to create new freely branching Mandevilla plants that flower freely and have attractive flowers that resist fading and sun scald.

The new Mandevilla plant originated from a cross-pollination conducted by the Inventor in Johannesburg, South Africa in January, 2014 of a proprietary selection of Mandevilla sanderi identified as code number D11-2149-1, not patented, as the female, or seed parent with a proprietary selection of Mandevilla sanderi identified as code number D11-2065-2, not patented, as the male, or pollen, parent. The new Mandevilla 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 greenhouse environment in Heidesheim, Germany in June, 2015.

Asexual reproduction of the new Mandevilla plant by vegetative cuttings in a controlled greenhouse environment in Heidesheim, Germany since August, 2015 has shown that the unique features of this new Mandevilla plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Mandevilla 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 ‘Inmanburg’. These characteristics in combination distinguish ‘Inmanburg’ as a new and distinct Mandevilla plant:

    • 1. Upright and vining plant habit.
    • 2. Moderately vigorous growth habit.
    • 3. Freely branching habit.
    • 4. Moderately glossy dark green-colored leaves.
    • 5. Freely flowering habit.
    • 6. Dark red to greyed purple-colored flowers with greyed orange-colored centers.
    • 7. Relatively tolerant to low temperatures.

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

    • 1. Plants of the new Mandevilla are more freely branching than plants of the female parent selection.
    • 2. Plants of the new Mandevilla have smoother flowers than plants of the female parent selection.
    • 3. Plants of the new Mandevilla have dark red to greyed purple-colored flowers with greyed orange-colored centers whereas plants of the female parent selection have dark red-colored flowers.

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

    • 1. Plants of the new Mandevilla are smoother leaves than plants of the male parent selection.
    • 2. Plants of the new Mandevilla have dark red to greyed purple-colored flowers with greyed orange-colored centers whereas plants of the male parent selection have dark red-colored flowers.

Plants of the new Mandevilla can also be compared to plants of Mandevilla x amabilis ‘Sunparacore’, disclosed in U.S. Plant Pat. No. 23,959. In side-by-side comparisons plants of the new Mandevilla differ primarily from plants ‘Sunparacore’ in the following characteristics:

    • 1. Plants of the new Mandevilla are more freely branching than plants of ‘Sunparacore’.
    • 2. Plants of the new Mandevilla have larger and more open flowers than plants of ‘Sunparacore’.
    • 3. Flowers of plants of the new Mandevilla are resistant sun scald whereas flowers of plants of ‘Sunparacore’ are not resistant to sun scald.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Mandevilla 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 actual colors of the new Mandevilla plant.

The photograph on the first sheet comprises a side perspective view of a typical flowering plant of ‘Inmanburg’ grown in a container.

The photograph on the second sheet is a close-up view of a typical flowering plant of ‘Inmanburg’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown during the spring and summer in 11-cm containers with wooden support frames in a glass-covered greenhouse in Heidesheim, Germany and under cultural practices typical of commercial Mandevilla production. During the production of the plants, day temperatures ranged from 20° C. to 40° C. and night temperatures ranged from 15° C. to 25° C. Plants were four months old when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2015 Edition, except where general terms of ordinary dictionary significance are used.
