plant named ‘Sunpararenga’

Abstract

A new and distinct cultivar of Mandevilla plant named ‘Sunpararenga’, characterized by its upright and vining plant habit; relatively small glossy foliage; freely branching habit; freely flowering habit; deep red-colored flowers; and long flowering period.

Description

Botanical designation: Mandevilla hybrida.

Cultivar denomination: ‘Sunpararenga’.

BACKGROUND OF THE INVENTION

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

The new Mandevilla plant is a product of a planned breeding program conducted by the Inventor in Higashiomi, Shiga, Japan. The objective of the breeding program is to create new compact, vining and freely-branching Mandevilla cultivars with numerous attractive flowers.

The new Mandevilla originated from a cross-pollination made by the Inventor in Higashiomi, Shiga, Japan in February, 2002, of a proprietary selection of Mandevilla hybrida identified as code number M35-4, not patented, as the female, or seed parent with a proprietary selection of Mandevilla hybrida identified as code number M28-3, not patented, as the male, or pollen, parent. The new Mandevilla 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 Higashiomi, Shiga, Japan in November, 2003.

Asexual reproduction of the new Mandevilla plant by cuttings in Higashiomi, Shiga, Japan, since December, 2003, 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. The phenotype may vary somewhat with variations in environment 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 ‘Sunpararenga’. These characteristics in combination distinguish ‘Sunpararenga’ as a new and distinct cultivar:

• • 1. Upright and vining plant habit.
  • 2. Relatively small glossy foliage.
  • 3. Freely branching habit.
  • 4. Freely flowering habit.
  • 5. Deep red-colored flowers.
  • 6. Long flowering period.

Plants of the new Mandevilla can be compared to plants of the female parent selection. Plants of the new Mandevilla differ from plants of the female parent selection in the following characteristics:

• • 1. Leaves of plants of the new Mandevilla are elliptic in shape whereas leaves of plants of the female parent selection are ovate in shape.
  • 2. Plants of the new Mandevilla and the female parent selection differ in flower color as plants of the female parent selection have lighter red-colored flowers.

Plants of the new Mandevilla can be compared to plants of the male parent selection. Plants of the new Mandevilla differ from plants of the male parent selection in the following characteristics:

• • 1. Plants of the new Mandevilla have thicker stems than 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 light pink-colored flowers.

Plants of the new Mandevilla can be compared to plants of the Mandevilla ‘Sunmanderemi’, disclosed in a U.S. Plant Pat. No. 16,449. Plants of the new Mandevilla differ from plants of ‘Sunmanderemi’ in the following characteristics:

• • 1. Plants of the new Mandevilla have thicker stems than plants of ‘Sunmanderemi’.
  • 2. Plants of the new Mandevilla have shorter internodes than plants of ‘Sunmanderemi’.
  • 3. Plants of the new Mandevilla have larger leaves than plants of ‘Sunmanderemi’.
  • 4. Plants of the new Mandevilla have smaller flowers than plants of ‘Sunmanderemi’.
  • 5. Plants of the new Mandevilla and ‘Sunmanderemi’ differ in flower color as plants of ‘Sunmanderemi’ have lighter red-colored flowers.
