Description

Botanical designation: Mandevilla sanderi.

Cultivar Denomination: ‘LANSOUTHDAKOTA’.

STATEMENT REGARDING PRIOR DISCLOSURES BY THE INVENTOR/APPLICANT & ASSIGNEE

An European Community Plant Breeder's Rights application for the instant plant was filed by the D.H.M. Innovations S.A.S. of Malause, France on Nov. 30, 2020, application number 2020/3084. Foreign priority is not claimed to this application.

The Inventor/Applicant and Assignee assert that no publications nor advertisements relating to sales, offers for sale or public distribution occurred more than one year prior to the effective filing date of this application. Any information about the claimed plant would have been obtained from a direct or indirect disclosure from the Inventor/Applicant and/or the Assignee. Inventor/Applicant and Assignee claim a prior art exception under 35 U.S.C. 102(b)(1) for disclosure and/or sales prior to the filing date but less than one year prior to the effective filing date.

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 ‘Lansouthdakota’.

The new Mandevilla plant is a product of a planned breeding program conducted by the Inventor in Malause, France. The objective of the breeding program is to create new freely branching Mandevilla plants with numerous unique and attractive flowers.

The new Mandevilla plant originated from a cross-pollination conducted by the Inventor in Malause, France in July, 2017 of a proprietary selection of Mandevilla sanderi identified as code number si 14-0028-002, not patented, as the female, or seed, parent with Mandevilla sanderi ‘Sunpapri’, disclosed in U.S. Plant Pat. No. 28,277, 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 Malause, France in June, 2018.

Asexual reproduction of the new Mandevilla plant by stein cuttings in a controlled greenhouse environment in Malause, France since August, 2019 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 ‘Lansouthdakota’. These characteristics in combination distinguish ‘Lansouthdakota’ as a new and distinct Mandevilla plant:

    • 1. Broadly upright and semi-vining plant habit.
    • 2. Moderately vigorous growth habit.
    • 3. Glossy dark green-colored leaves.
    • 4. Early and freely flowering habit.
    • 5. Large flowers with pale yellow and yellowish pink-colored petals with reddish orange-colored star-shaped centers.

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 vigorous than plants of the female parent selection.
    • 2. Leaves of plants of the new Mandevilla are narrower than and not as rounded as leaves of plants of the female parent selection.
    • 3. Plants of the new Mandevilla have pale yellow and yellowish pink-colored petals with reddish orange-colored star-shaped centers whereas plants of the female parent selection have yellow-colored petals.

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

    • 1. Plants of the new Mandevilla have sturdier flower petals than plants of ‘Sunpapri’.
    • 2. Plants of the new Mandevilla have pale yellow and yellowish pink-colored petals with reddish orange-colored star-shaped centers whereas plants of ‘Sunpapri’ have light to pale orange-colored petals.
    • 3. Flowers of plants of the new Mandevilla resist color fading under full sunlight conditions whereas flowers of plants of ‘Sunpapri’ fade under full sunlight conditions.

Plants of the new Mandevilla can also be compared to plants of Mandevilla sanderi ‘Lancalifornia’, disclosed in U.S. Plant Pat. No. 24,074. In side-by-side comparisons, plants of the new Mandevilla differ primarily from plants ‘Lancalifornia’ in the following characteristics:

    • 1. Plants of the new Mandevilla are more compact than plants of ‘Lancalifornia’.
    • 2. Leaves of plants of the new Mandevilla are narrower than and not as rounded as leaves of plants of ‘Lancalifornia’.
    • 3. Flowers of plants of the new Mandevilla are star-shaped whereas flowers of plants of ‘Lancalifornia’ are more rounded.
    • 4. Plants of the new Mandevilla have pale yellow and yellowish pink-colored petals with reddish orange-colored star-shaped centers whereas plants of ‘Lancalifornia’ have yellow-colored petals.

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 (FIG. 1) comprises a side perspective view of a typical flowering plant of ‘Lancalifornia’ grown in a container.

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

 DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown during the autumn in 11-cm containers in a polyethylene-covered greenhouse in Malause, France and under cultural practices typical of commercial Mandevilla production.
