Hibiscus plant named ‘Maui Wind’

Abstract

A new and distinct Hibiscus plant named ‘Maui Wind’, characterized by its compact, upright, outwardly spreading, uniform, dense and symmetrical plant habit that is appropriate for container production; glossy and dark green-colored leaves; uniform and freely flowering habit; light pink-colored flowers with dark red-colored centers; good resistance to flower bud abscission during shipping; and tolerance to pathogens common to Hibiscus grown under Florida production conditions.

Description

Botanical designation: Hibiscus rosa-sinensis.

Cultivar denomination: ‘Maui Wind’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Hibiscus, botanically known as Hibiscus rosa-sinensis, and hereinafter referred to by the name ‘Maui Wind’.

The new Hibiscus is a product of a planned breeding program conducted by the Inventor in Alva, Fla. The objective of the breeding program is to create new freely-branching Hibiscus cultivars with a dense, uniform and compact plant habit appropriate for container production, early and uniform flowering, numerous flowers per lateral branch, desirable flower color and good postproduction longevity.

The new Hibiscus originated from a cross-pollination made by the Inventor in Alva, Fla. in late 1998, of a proprietary Hibiscus rosa-sinensis selection, designated as code number YB-1460, not patented, as the female, or seed, parent with a proprietary Hibiscus rosa-sinensis selection, designated as code number YB-1934, not patented, as the male, or pollen, parent. The cultivar Maui Wind was discovered and selected by the Inventor as a flowering plant within the progeny of the stated cross-pollination in a controlled environment in Alva, Fla., on Sep. 14, 2000.

Asexual reproduction of the new Hibiscus by vegetative terminal cuttings in a controlled environment in Alva, Fla. since February, 2001, has shown that the unique features of this new Hibiscus are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The cultivar Maui Wind has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environmental and cultural practices 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 ‘Maui Wind’. These characteristics in combination distinguish ‘Maui Wind’ as a new and distinct cultivar:

• • 1. Upright, outwardly spreading, uniform, dense and symmetrical plant habit that is appropriate for container production.
  • 2. Glossy and dark green-colored leaves.
  • 3. Uniform and freely flowering habit.
  • 4. Light pink-colored flowers with dark red-colored centers.
  • 5. Good resistance to flower bud abscission during shipping.
  • 6. Tolerant to pathogens common to Hibiscus grown under Florida production conditions.

Plants of the new Hibiscus can be compared to plants of the female parent, the proprietary Hibiscus selection code number YB-1460. Plants of the new Hibiscus differ from plants of the female parent selection in the following characteristics:

• • 1. Plants of the new Hibiscus have darker green-colored leaves than plants of the female parent selection.
  • 2. Plants of the new Hibiscus and the female parent selection differ in flower color as plants of the female parent selection have yellow-colored flowers.

Plants of the new Hibiscus can be compared to plants of the male parent, the proprietary Hibiscus selection code number YB-1934. Plants of the new Hibiscus differ from plants of the male parent selection in the following characteristics:

• • 1. Plants of the new Hibiscus are more vigorous than plants of the male parent selection.
  • 2. Plants of the new Hibiscus and the male parent selection differ in flower color as flowers of plants of the male parent selection do not have dark red-colored centers.

Plants of the new Hibiscus can be compared to plants of the Hibiscus cultivar Candy Wind, disclosed in U.S. Plant Pat. No. 11,759. In side-by-side comparisons conducted in Alva, Fla., plants of the new Hibiscus differed from plants of the cultivar Candy Wind in the following characteristics:

• • 1. Plants of the new Hibiscus had darker green-colored leaves than plants of the cultivar Candy Wind.
  • 2. Plants of the new Hibiscus had lighter pink-colored flowers than plants of the cultivar Candy Wind.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Hibiscus, 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 colors of the new Hibiscus.

The photograph on the first sheet comprises a side perspective view of five typical flowering plants of ‘Maui Wind’ grown in a container.

The photograph on the second sheet comprises a close-up view of a typical flower of ‘Maui Wind’.

DETAILED BOTANICAL DESCRIPTION

The photographs and following observations, measurements and values describe plants grown in Alva, Fla., with five plants per 16.5-cm container in polyethylene-covered greenhouses during the late summer under conditions which closely approximate commercial production. During the production of the plants, day temperatures ranged from 16 to 37° C. and night temperatures ranged from 13 to 26° C. Plants were about four months old when the photographs and the description were taken. In the description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
