Abstract

A new and distinct cultivar of Hibiscus plant named ‘Pink Kai’, characterized by its compact, upright, outwardly spreading and dense plant habit that is appropriate for container production; glossy medium green-colored leaves; uniform, freely and early flowering habit; large dark pink-colored flowers; and good postproduction and garden performance.

Description

Botanical designation: Hibiscus rosa-sinensis.
Cultivar denomination: ‘Pink Kai’.
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 ‘Pink Kai’.
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 garden performance.
The new Hibiscus originated from a cross-pollination made by the Inventor in Alva, Fla. in February, 2004, of Hibiscus rosa-sinensis ‘Cajun Wind’, disclosed in U.S. Plant Pat. No. 17,589, as the female, or seed, parent with Hibiscus rosa-sinensis ‘Casa Grande Soft Pink’, not patented, as the male, or pollen, parent. The new Hibiscus was discovered and selected by the Inventor as a flowering plant within the progeny of the stated cross-pollination in a controlled greenhouse environment in Alva, Fla. on Aug. 22, 2005.
Asexual reproduction of the new Hibiscus by vegetative terminal cuttings in a controlled greenhouse environment in Alva, Fla. since February, 2006, has shown that the unique features of this new Hibiscus are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
Plants of the new Hibiscus have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment 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 ‘Pink Kai’. These characteristics in combination distinguish ‘Pink Kai’ as a new and distinct cultivar of Hibiscus:
    • 1. Compact, upright, outwardly spreading and dense plant habit that is appropriate for container production.
    • 2. Glossy medium green-colored leaves.
    • 3. Uniform, freely and early flowering habit.
    • 4. Large dark pink-colored flowers.
    • 5. Good postproduction and garden performance.
Plants of the new Hibiscus can be compared to plants of the female parent, ‘Cajun Wind’. Plants of the new Hibiscus differ primarily from plants of ‘Cajun Wind’ in flower color as plants of ‘Cajun Wind’ have red-colored flowers.
Plants of the new Hibiscus can be compared to plants of the male parent, ‘Casa Grande Soft Pink’. Plants of the new Hibiscus differ from plants of ‘Casa Grande Soft Pink’ in the following characteristics:
    • 1. Plants of the new Hibiscus have smaller flowers than plants of ‘Casa Grande Soft Pink’.
    • 2. Plants of the new Hibiscus and ‘Casa Grande Soft Pink’ differ in flower color as plants of ‘Casa Grande Soft Pink’ have light pink-colored flowers.
Plants of the new Hibiscus can be compared to plants of the Hibiscus rosa-sinensis ‘Maui Wind’, disclosed in U.S. Plant Pat. No. 17,569. In side-by-side comparisons conducted in Alva, Fla., plants of the new Hibiscus differed from plants of ‘Maui Wind’ in the following characteristics:
    • 1. Plants of the new Hibiscus were denser than and not as open as plants of ‘Maui Wind’.
    • 2. Plants of the new Hibiscus had lighter green-colored leaves than plants of ‘Maui Wind’.
    • 3. Flowers of plants of the new Hibiscus and ‘Maui Wind’ differed in flower color as plants of ‘Maui Wind’ had light pink-colored flowers.
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 at the bottom of the sheet comprises a side perspective view of typical flowering plants of ‘Pink Kai’ grown in a container.
The photograph at the top of the sheet comprises a close-up view of a typical flower of ‘Pink Kai’.
 DETAILED BOTANICAL DESCRIPTION
The aforementioned photographs and following observations, measurements and values describe plants grown in Bonsall, Calif. in one-gallon containers in polyethylene-covered greenhouses during the spring under conditions which closely approximate commercial production. During the production of the plants, day temperatures ranged from about 18° C. to about 38° C. and night temperatures ranged from about 16° C. to about 21° C. Plants had been growing for 18 weeks when the photographs and the description were taken. In the description, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used.
