Abstract

A new and distinct cultivar of Mandevilla plant named ‘Lannevada’, characterized by its trailing plant habit; moderately vigorous growth habit; glossy dark green-colored leaves; early flowering habit; and red-colored flowers.

Description

Botanical designation: Mandevilla sanderi.

Cultivar denomination: ‘LANNEVADA’.

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 ‘Lannevada’.

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 trailing Mandevilla plants with red-colored flowers.

The new Mandevilla plant originated from a cross-pollination conducted by the Inventor in Malause, France on Sep. 22, 2006 of Mandevilla sanderi ‘Sunmanderemi’, disclosed in U.S. Plant Pat. No. 16,449, as the female, or seed parent with a proprietary selection of Mandevilla sanderi identified as code number 05-075-22, 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 May, 2008.

Asexual reproduction of the new Mandevilla plant by cuttings in a controlled greenhouse environment in Malause, France, since May, 2010 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 ‘Lannevada’. These characteristics in combination distinguish ‘Lannevada’ as a new and distinct Mandevilla plant:

- 1. Trailing plant habit.
- 2. Moderately vigorous growth habit.
- 3. Glossy dark green-colored leaves.
- 4. Early flowering habit.
- 5. Red-colored flowers.

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

- 1. Leaves of plants of the new Mandevilla are flatter and thicker than leaves of plants of ‘Sunmanderemi’.
- 2. Plants of the new Mandevilla and ‘Sunmanderemi’ differ slightly in flower color.
- 3. Flowers of plants of the new Mandevilla are resistant to sun fading whereas flowers of plants of ‘Sunmanderemi’ are not resistant to sun fading.

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. Leaves of plants of the new Mandevilla are flatter and thicker than leaves of plants of the male parent selection.
- 2. Plants of the new Mandevilla and the male parent selection differ in flower color as plants of the male parent selection have pink-colored flowers.
- 3. Flowers of plants of the new Mandevilla are resistant to sun fading whereas flowers of plants of the male parent selection are not resistant to sun fading.

Plants of the new Mandevilla can also be compared to plants of Mandevilla sanderi ‘Sherry’, not patented. In side-by-side comparisons conducted in Malause, France, plants of the new Mandevilla differed from plants ‘Sherry’ in the following characteristics:

- 1. Plants of the new Mandevilla were more trailing than and not as upright as plants of ‘Sherry’.
- 2. Plants of the new Mandevilla were more vigorous than plants of ‘Sherry’.
- 3. Plants of the new Mandevilla flowered two weeks earlier than plants of ‘Sherry’.
- 4. Plants of the new Mandevilla had darker-colored flowers than plants of ‘Sherry’.

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 ‘Lannevada’ grown in a container.

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

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown during the autumn in two-liter 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 8° C. to 26° C. and night temperatures ranged from 3° C. to 15° C. Plants were six months old when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2007 Edition, except where general terms of ordinary dictionary significance are used.
