plant named ‘MAN222903’

Abstract

A new and distinct cultivar of Mandevilla plant named ‘MAN222903’, characterized by its relatively compact, upright to spreading and vining plant habit; vigorous growth habit; glossy dark green-colored leaves; early and freely flowering habit; and purplish red-colored flowers.

Description

Botanical designation: Mandevilla sanderi.

Cultivar denomination: ‘MAN222903’.

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 ‘MAN222903’.

The new Mandevilla plant is a product of a planned breeding program conducted by the Inventor in De Kwakel, The Netherlands. The objective of the breeding program is to create new freely-flowering Mandevilla plants with large attractive flowers and good container performance.

The new Mandevilla plant originated from a cross-pollination in De Kwakel, The Netherlands in May, 2015 of Mandevilla sanderi ‘MAN216901’, disclosed in U.S. Plant Pat. No. 29,001, as the female, or seed parent with a proprietary selection of Mandevilla sanderi identified as code number 13-0145-046, 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 De Kwakel, The Netherlands in May, 2017.

Asexual reproduction of the new Mandevilla plant by vegetative cuttings in a controlled greenhouse environment in De Kwakel, The Netherlands, since August, 2017 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 ‘MAN222903’. These characteristics in combination distinguish ‘MAN222903’ as a new and distinct Mandevilla plant:

• • 1. Relatively compact, upright to spreading and vining plant habit.
  • 2. Vigorous growth habit.
  • 3. Glossy dark green-colored leaves.
  • 4. Early and freely flowering habit.
  • 5. Purplish red-colored flowers.

Plants of the new Mandevilla can be compared to plants of the female parent, ‘MAN216901’. Plants of the new Mandevilla differ primarily from plants of ‘MAN216901’ in flower color as plants of the new Mandevilla have purplish red-colored flowers whereas plants of ‘MAN216901’ have white-colored flowers. In addition, plants of the new Mandevilla are more compact than plants of ‘MAN216901’.

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 male parent selection in plant habit as plants of the new Mandevilla are more compact than plants of the male parent selection.

Plants of the new Mandevilla can be compared to plants of Mandevilla sanderi ‘MAN217901’, disclosed in U.S. Plant Pat. No. 29,708. In side-by-side comparisons, plants of the new Mandevilla differ primarily from plants ‘MAN217901’ in the following characteristics:

• • 1. Plants of the new Mandevilla are more compact than plants of ‘MAN217901’.
  • 2. Plants of the new Mandevilla grow slower than plants of ‘MAN217901’.
  • 3. Plants of the new Mandevilla have smaller flowers than plants of ‘MAN217901’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown during the late spring in 19-cm containers in a glass-covered greenhouse in De Kwakel, The Netherlands and under cultural practices typical of Mandevilla commercial production. During the production of the plants, day temperatures ranged from 20 C to 22 C and night temperatures averaged 18 C. Plants were pinched one time four weeks after planting and were twelve months old when the photographs and description were taken.
