Description

Botanical designation: Mandevilla sanderi.

Cultivar denomination: ‘LANNORTHDAKOTA’.

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. 24, 2020, application number 2020/2971. 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 exemption 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 ‘Lannorthdakota’.

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 vigorous and 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 during the spring of 2016 of a proprietary selection of Mandevilla sanderi identified as code number si u231-0, not patented, as the female, or seed, parent with Mandevilla sanderi ‘Lanmalause’, 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 Malause, France during the spring/summer of 2018.

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

    • 1. Broadly vining plant habit.
    • 2. Moderately vigorous to vigorous growth habit.
    • 3. Freely branching habit.
    • 4. Glossy dark green-colored leaves.
    • 5. Early and freely flowering habit.
    • 6. Flowers with rounded red purple-colored petals and broad dark yellow-colored throats.

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 vining than and not as compact and upright as plants of the female parent selection.
    • 2. Flowers of plants of the new Mandevilla have rounded red purple-colored petals and broad dark yellow-colored throats whereas flowers of plants of the female parent selection have pointed white-colored petals with narrow orange-colored throats.

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

    • 1. Plants of the new Mandevilla are more vining than and not as compact as plants of ‘Lanmalause’.
    • 2. Plants of the new Mandevilla are more freely branching than plants of ‘Lanmalause’.
    • 3. Flower petals of plants of the new Mandevilla are red purple in color whereas flower petals of plants of ‘Lanmalause’ are red orange in color.
    • 4. Flowers of plants of the new Mandevilla resist fading under high light exposure whereas flowers of ‘Lanmalause’ fade under high light exposure.

Plants of the new Mandevilla can also be compared to plants of Mandevilla sanderi ‘Rosea Fonce’, not patented. In side-by-side comparisons, plants of the new Mandevilla differ primarily from plants ‘Rosea Fonce’ in the following characteristics:

    • 1. Plants of the new Mandevilla are more freely branching than plants of ‘Rosea Fonce’.
    • 2. Plants of the new Mandevilla flower much earlier than plants of ‘Rosea Fonce’.
    • 3. Plants of the new Mandevilla have larger flowers than plants of ‘Rosea Fonce’.

Plants of the new Mandevilla can also be compared to plants of Mandevilla sanderi ‘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 vining and vigorous than plants of ‘Sunparapibra’.
    • 2. Flowers of plants of the new Mandevilla have red purple-colored petals and broad dark yellow-colored throats whereas flowers of plants of ‘Sunparapibra’ have light pink-colored petals with narrow orange-colored throats.
    • 3. Plants of the new Mandevilla are more resistant to fungal pathogens than 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 (FIG. 1) comprises a side perspective view of a typical flowering plant of ‘Lannorthdakota’ grown in a container.

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

 DETAILED BOTANICAL DESCRIPTION
