plant named ‘Lannorthcarolina’

Abstract

A new and distinct cultivar of Mandevilla plant named ‘Lannorthcarolina’, characterized by its upright and twining plant habit; moderately vigorous to vigorous growth habit; large glossy dark green-colored leaves; and large pink-colored flowers.

Description

Botanical designation: Mandevilla hybrida.

Cultivar denomination: ‘LANNORTHCAROLINA’.

BACKGROUND OF THE INVENTION

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

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 upright Mandevilla plants with large leaves and flowers.

The new Mandevilla plant originated from a cross-pollination conducted by the Inventor in Malause, France in June, 2009 of Mandevilla hybrida ‘Sunmandeho’, disclosed in U.S. Plant Pat. No. 11,556, as the female, or seed parent with a proprietary selection of Mandevilla hybrida identified as code number 06-823-01, 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, 2012.

Asexual reproduction of the new Mandevilla plant by cuttings in a controlled greenhouse environment in Malause, France, since December, 2012 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 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 ‘Lannorthcarolina’. These characteristics in combination distinguish ‘Lannorthcarolina’ as a new and distinct Mandevilla plant:

• • 1. Upright and twining plant habit.
  • 2. Moderately vigorous to vigorous growth habit.
  • 3. Large glossy dark green-colored leaves.
  • 4. Large pink-colored flowers.

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

• • 1. Plants of the new Mandevilla are more upright than and not as vining as plants of ‘Sunmandeho’.
  • 2. Plants of the new Mandevilla have shorter internodes than plants of ‘Sunmandeho’.
  • 3. Plants of the new Mandevilla and ‘Sunmandeho’ differ in flower color as plants of ‘Sunmandeho’ have yellowish white-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 have larger leaves than plants of the male parent selection.
  • 2. Plants of the new Mandevilla have larger flowers than plants of the male parent selection.
  • 3. Plants of the new Mandevilla and the male parent selection differ in flower color as plants of the male parent selection have red-colored flowers.

Plants of the new Mandevilla can also be compared to plants of Mandevilla sanderi ‘Lanarizona’, disclosed in U.S. Plant Pat. No. 23,672. In side-by-side comparisons conducted in Malause, France, plants of the new Mandevilla differed primarily from plants of ‘Lanarizona’ in flower color as plants of ‘Lanarizona’ have white-colored flowers. In addition, plants of the new Mandevilla had shorter internodes and were more upright than and not as vining as plants of ‘Lanarizona’.

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 ‘Lannorthcarolina’ grown in a container.

The photograph on the second sheet is a close-up view of typical flower buds and open flowers of ‘Lannorthcarolina’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown during the spring in 17-cm containers in polyethylene-covered greenhouse in Malause, France and under cultural practices typical of Mandevilla commercial production. During the production of the plants, day temperatures ranged from 15° C. to 26° C. and night temperatures ranged from 14° C. to 15° C. Plants were six months old when the photographs and description were taken.
