Botanical designation:Hibiscus rosa-sinensis.
Cultivar denomination: `Tye-Dye Wind`.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Hibiscus, botanically known as Hisbiscus rosa-sinensis, and hereinafter referred to by the name `Tye-Dye 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 habitappropriate 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 early 1999, of the Hibiscus rosa-sinensis cultivar Captiva Wind, disclosed in U.S. Plant patent application Ser. No. 10/156,544, as the female, or seed,parent with a proprietary Hibiscus rosa-sinensis selection, designated as code number YB-1715, not patented, as the male, or pollen, parent. The cultivar `Tye-Dye Wind` was discovered and selected by the Inventor as a flowering plant within the progenyof the stated cross-pollination in a controlled environment in Alva, Fla. on Sep. 6, 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 successivegenerations.
SUMMARY OF THE INVENTION
The cultivar `Tye-Dye Wind` has 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, anyvariance in genotype.
The following traits have been repeatedly observed and are determined to be the unique characteristics of `Tye-Dye Wind`. These characteristics in combination distinguish `Tye-Dye Wind` as a new and distinct cultivar of Hibiscus: 1. Compact,upright, somewhat outwardly spreading, uniform, dense and symmetrical plant habit that is appropriate for container production. 2. Glossy dark green-colored leaves. 3. Uniform, freely and early flowering habit. 4. Large mottled light red andpink-colored flowers. 5. Good resistance to flower bud abscission during shipping. 6. Not susceptible 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 cultivar Captiva Wind. Plants of the new Hibiscus differ from plants of the cultivar Captiva Wind in the following characteristics: 1. Plants of the new Hibiscushave leaves with entire margins whereas plants of the cultivar Captiva Wind have deeply-lobed leaves. 2. Plants of the new Hibiscus and the cultivar Captiva Wind differ in flower coloration as plants of the cultivar Captiva Wind have lavender-coloredflowers with pink-colored margins.
Plants of the new Hibiscus can be compared to plants of the male parent, the proprietary Hibiscus selection code number YB-1715. Plants of the new Hibiscus differ from plants of the male parent selection in the following characteristics: 1. Plants of the new Hibiscus have smaller flowers than plants of the male parent selection. 2. Plants of the new Hibiscus and the male parent selection differ in flower coloration as plants of the male parent selection have creamy white-colored flowers.
Plants of the new Hibiscus can be compared to plants of the Hibiscus rosa-sinensis cultivar Belize Breeze, disclosed in U.S. Plant Pat. No. 17,492. In side-by-side comparisons conducted in Alva, Fla., plants of the new Hibiscus differed fromplants of the cultivar Belize Breeze in the following characteristics: 1. Plants of the new Hibiscus had leaves with entire margins whereas plants of the cultivar Belize Breeze had lobed leaves. 2. Plants of the new Hibiscus had smoother petal marginsthan plants of the cultivar Belize Breeze. 3. Flowers of plants of the new Hibiscus and the cultivar Belize Breeze differed in flower color as plants of the cultivar Belize Breeze had bright pink-colored flowers.

DETAILED BOTANICAL DESCRIPTION
The photographs and following observations, measurements and values describe plants grown in Alva, Fla. in 15-cm containers in polycarbonate-covered greenhouses during the spring under conditions which closely approximate commercial production. During the production of the plants, day temperatures ranged from about 16° C. to about 37° C. and night temperatures ranged from about 7° C. to about 26° C. Plants were about four months old when the photographs and thedescription 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.
