plant named ‘Lanutah’

Abstract

A new and distinct cultivar of Mandevilla plant named ‘Lanutah’, characterized by its vining plant habit; moderately vigorous to vigorous growth habit; glossy small dark green-colored leaves; early and freely flowering habit; and dark red purple-colored flowers.

Description

Botanical designation: Mandevilla Sanderi.

Cultivar denomination: ‘LANUTAH’.

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 ‘Lanutah’.

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 vining Mandevilla plants with dark red purple-colored flowers.

The new Mandevilla plant originated from a cross-pollination conducted by the Inventor in Malause, France on Aug. 20, 2006 of a proprietary selection of Mandevilla Sanderi identified as code number 05-075-22, not patented, as the female, or seed parent with Mandevilla Sanderi ‘Sunmanderemi’, disclosed in U.S. Plant Pat. No. 16,449, 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 ‘Lanutah’. These characteristics in combination distinguish ‘Lanutah’ as a new and distinct Mandevilla plant:

• • 1. Vining plant habit.
  • 2. Moderately vigorous to vigorous growth habit.
  • 3. Glossy small dark green-colored leaves.
  • 4. Early and freely flowering habit.
  • 5. Dark red purple-colored flowers.

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 flower earlier than plants of the female parent selection.
  • 2. Plants of the new Mandevilla have star-shaped flowers whereas plants of the female parent selection have rounded flowers.
  • 3. Plants of the new Mandevilla have larger flowers than plants of the female parent selection.

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

• • 1. Plants of the new Mandevilla flower earlier than plants of ‘Sunmanderemi’.
  • 2. Plants of the new Mandevilla have star-shaped flowers whereas plants of ‘Sunmanderemi’ have rounded flowers.
  • 3. Plants of the new Mandevilla have larger flowers than plants of ‘Sunmanderemi’.

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 of ‘Sherry’ in the following characteristics:

• • 1. Plants of the new Mandevilla were more vigorous than plants of ‘Sherry’.
  • 2. Plants of the new Mandevilla were more freely flowering than plants of ‘Sherry’.
  • 3. Plants of the new Mandevilla had larger flowers than plants of ‘Sherry’.
  • 4. Flowers of plants of the new Mandevilla were darker in color than flowers of plants of ‘Sherry’.
