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 ‘Lannewyork’.

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, 2016 of a proprietary selection of Mandevilla sanderi identified as code number si 08-0426-044, not patented, as the female, or seed, parent with a proprietary selection of Mandevilla sanderi identified as code number si s346-0, 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 in June, 2017.

Asexual reproduction of the new Mandevilla plant by stem 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 ‘Lannewyork’. These characteristics in combination distinguish ‘Lannewyork’ as a new and distinct Mandevilla plant:

• • 1. Compact, broadly upright and vining plant habit.
  • 2. Moderately vigorous growth habit.
  • 3. Freely branching habit.
  • 4. Glossy dark green-colored leaves.
  • 5. Early and freely flowering habit.
  • 6. Large flowers with red-colored petals and greenish 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 compact and have shorter internodes than plants of the female parent selection.
  • 2. Plants of the new Mandevilla are more freely flowering than plants of the female parent selection.

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 more compact than plants of the male parent selection.
  • 2. Flowers of plants of the new Mandevilla have red-colored petals whereas flowers of plants of the male parent selection have rose-colored petals.

Plants of the new Mandevilla can also be compared to plants of Mandevilla x amabilis X Mandevilla hybrida ‘Lankentucky’, disclosed in U.S. Plant Pat. No. 29,849. In side-by-side comparisons, plants of the new Mandevilla differ primarily from plants ‘Lankentucky’ in the following characteristics:

• • 1. Plants of the new Mandevilla have larger and more rounded leaves than plants of ‘Lankentucky’.
  • 2. Flowers of plants of the new Mandevilla have red-colored petals whereas flowers of plants of ‘Lankentucky’ have brighter red-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 ‘Lannewyork’ grown in a container.

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