plant named ‘Sunpavariaka’

Abstract

A new and distinct cultivar of Mandevilla plant named ‘Sunpavariaka’, characterized by its vining plant habit; vigorous growth habit; freely branching habit; variegated leaves; early flowering habit; long flowering period; and numerous red-colored flowers.

Description

Botanical designation: Mandevilla hybrida.

Cultivar denomination: ‘SUNPAVARIAKA’.

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 ‘Sunpavariaka’.

The new Mandevilla plant is a naturally-occurring branch mutation of Mandevilla hybrida ‘Sunmandecrikin’, disclosed in U.S. Plant Pat. No. 17,736. The new Mandevilla plant was discovered and selected by the Inventor on a single flowering plant of the proprietary selection in a controlled nursery environment in Sarasota, Fla. in May, 2015.

Asexual reproduction of the new Mandevilla plant by terminal vegetative cuttings in Sarasota, Fla. since October, 2015 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 ‘Sunpavariaka’. These characteristics in combination distinguish ‘Sunpavariaka’ as a new and distinct Mandevilla plant:

• • 1. Vining plant habit.
  • 2. Vigorous growth habit.
  • 3. Freely branching habit.
  • 4. Variegated leaves.
  • 5. Early flowering habit.
  • 6. Long flowering period.
  • 7. Numerous red-colored flowers.

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

• • 1. Plants of the new Mandevilla have smaller leaves than plants of ‘Sunmandecrikin’.
  • 2. Plants of the new Mandevilla and ‘Sunmandecrikin’ differ in leaf color as plants of ‘Sunmandecrikin’ have variegated leaves.
  • 3. Plants of the new Mandevilla have smaller flowers than plants of ‘Sunmandecrikin’.

Plants of the new Mandevilla can be compared to plants of the Mandevilla splendens ‘FGRRV1’, disclosed in U.S. Plant Pat. No. 28,446. In side-by-side comparisons, plants of the new Mandevilla differ from plants of ‘FGRRV1’ in the following characteristics:

• • 1. Leaves of plants of the new Mandevilla are lanceolate in shape whereas leaves of plants of ‘FGRRV1’ are elliptic to ovate in shape.
  • 2. Plants of the new Mandevilla and ‘FGRRV1’ differ in leaf color as plants of ‘FGRRV1’ have medium green and creamy white variegated leaves.
  • 3. Plants of the new Mandevilla and ‘FGRRV1’ differ in flower color as plants of ‘FGRRV1’ have red purple-flowers with yellow-colored flower throats.

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 ‘Sunpavariaka’ grown in a container.

The photograph at the bottom of the sheet is a close-up view of a typical flowering plant of ‘Sunpavariaka’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown during the late summer in 15-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, 2015 Edition, except where general terms of ordinary dictionary significance are used.
