Abstract

A new and distinct cultivar of Mandevilla plant named ‘MAN217901’, characterized by its upright and spreading plant habit; vigorous growth habit; freely branching habit; relatively small glossy green-colored leaves; early and freely flowering habit; and large flowers with broad red purple-colored petals.

Description

Botanical designation: Mandevilla sanderi.

Cultivar denomination: ‘MAN217901’.

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 ‘MAN217901’.

The new Mandevilla plant is a product of a planned breeding program conducted by the Inventor in De Kwakel, The Netherlands. The objective of the breeding program is to create new freely-flowering Mandevilla plants with large and attractive flowers.

The new Mandevilla plant originated from an open-pollination in De Kwakel, The Netherlands in May, 2012 of a proprietary selection of Mandevilla sanderi identified as code number 11-0006-000, not patented, as the female, or seed parent with an unknown selection of Mandevilla sanderi 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 open-pollination in a controlled greenhouse environment in De Kwakel, The Netherlands in May, 2014.

Asexual reproduction of the new Mandevilla plant by vegetative cuttings in a controlled greenhouse environment in De Kwakel, The Netherlands, since August, 2014 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 ‘MAN217901’. These characteristics in combination distinguish ‘MAN217901’ as a new and distinct Mandevilla plant:

- 1. Upright and spreading plant habit.
- 2. Vigorous growth habit.
- 3. Freely branching habit.
- 4. Relatively small glossy green-colored leaves.
- 5. Early and freely flowering habit.
- 6. Large flowers with broad red purple-colored petals.

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 flower color as plants of the female parent selection have white-colored flowers.

Plants of the new Mandevilla can be compared to plants of Mandevilla hybrida ‘Sunparapibra’, disclosed in U.S. Plant Pat. No. 19,649. In side-by-side comparisons, plants of the new Mandevilla differ primarily from plants ‘Sunparapibra’ in the following characteristics:

- 1. Plants of the new Mandevilla are more vigorous than plants of ‘Sunparapibra’.
- 2. Plants of the new Mandevilla are more freely branching than plants of ‘Sunparapibra’.
- 3. Plants of the new Mandevilla flower earlier than plants of ‘Sunparapibra’.
- 4. Plants of the new Mandevilla are more freely flowering than plants of ‘Sunparapibra’.
- 5. Plants of the new Mandevilla have larger flowers than plants of ‘Sunparapibra’.
- 6. Petals of plants of the new Mandevilla are darker red purple in color than petals of plants of ‘Sunparapibra’.

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 is a side perspective view of typical flowering plant of ‘MAN217901’ grown in a container.

The photograph on the second sheet is close-up view of a typical flowering plant of ‘MAN217901’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown during the late spring in 19-cm containers in a glass-covered greenhouse in De Kwakel, The Netherlands and under cultural practices typical of Mandevilla commercial production. During the production of the plants, day temperatures ranged from 20° C. to 22° C. and night temperatures averaged 18° C. Plants were pinched one time four weeks after planting. Plants were twelve 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.
