plant named ‘Sunparapreho’

Abstract

A new and distinct cultivar of Mandevilla plant named ‘Sunparapreho’, characterized by its vining plant habit; moderately vigorous growth habit; freely branching habit; dark green-colored leaves; freely flowering habit; long flowering period; and medium-sized white-colored flowers.

Description

Botanical designation: Mandevilla hybrida.

Cultivar denomination: ‘SUNPARAPREHO’.

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 ‘Sunparapreho’.

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 freely-branching and vining Mandevilla plants with numerous medium-sized attractive flowers.

The new Mandevilla plant originated from an open-pollination in Higashiomi, Shiga, Japan in October, 2009 of a proprietary selection of Mandevilla hybrida identified as code number 06M-28-09, not patented, as the female, or seed parent with an unknown proprietary selection of Mandevilla hybrida, 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 open-pollination in a controlled greenhouse environment in Higashiomi, Shiga, Japan in November, 2010.

Asexual reproduction of the new Mandevilla plant by cuttings in Higashiomi, Shiga, Japan since November, 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 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 ‘Sunparapreho’. These characteristics in combination distinguish ‘Sunparapreho’ as a new and distinct Mandevilla plant:

• • 1. Vining plant habit.
  • 2. Moderately vigorous growth habit.
  • 3. Freely branching habit.
  • 4. Dark green-colored leaves.
  • 5. Freely flowering habit.
  • 6. Long flowering period.
  • 7. Medium-sized white-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 have smaller flowers than plants of the female parent selection.
  • 2. Plants of the new Mandevilla and the female parent selection differ in flower color as plants of the female parent selection have red-colored flowers.

Plants of the new Mandevilla can be compared to plants of the Mandevilla×amabilis ‘Sunparamiho’, disclosed in U.S. Plant Pat. No. 22,868. In side-by-side comparisons conducted in Higashiomi, Shiga, Japan, plants of the new Mandevilla differed from plants of ‘Sunparamiho’ in the following characteristics:

• • 1. Plants of the new Mandevilla had shorter lateral branches with shorter internodes than plants of ‘Sunparamiho’.
  • 2. Plants of the new Mandevilla were not as vigorous as plants of ‘Sunparamiho’.
  • 3. Plants of the new Mandevilla had smaller leaves than plants of ‘Sunparamiho’.
  • 4. Plants of the new Mandevilla flowered earlier than plants of ‘Sunparamiho’.
  • 5. Plants of the new Mandevilla had shorter peduncles than plants of ‘Sunparamiho’.

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 at the top of the sheet comprises a side perspective view of a typical flowering plant of ‘Sunparapreho’ grown in a container.

The photograph at the bottom of the sheet is a close-up view of a typical flower of ‘Sunparapreho’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown during the late summer in 18-cm containers in an outdoor nursery in Higashiomi, Shiga, Japan and under cultural practices typical of commercial Mandevilla production. During the production of the plants, day temperatures averaged 25° C. and night temperatures averaged 15° C. Plants were six months old when the photographs and detailed 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.
