Botanical designation: Hibiscus rosa-sinensis.
Cultivar denomination: ‘CAYMAN WIND’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct Hibiscus plant, botanically known as Hibiscus rosa-sinensis and hereinafter referred to by the name ‘Cayman Wind’.
The new Hibiscus plant 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 plants with a dense, uniform and compact plant habit appropriate for container production, early and uniform flowering habit, numerous flowers per lateral branch, desirable flower color and good garden performance.
The new Hibiscus plant originated from a cross-pollination made by the Inventor in Alva, Fla. in September, 2007 of Hibiscus rosa-sinensis ‘Captiva Wind’, disclosed in U.S. Plant patent application Ser. No. 10/156,544 (abandoned), as the female, or seed, parent with a proprietary selection of Hibiscus rosa-sinensis identified as code number YB-2336, not patented, as the male, or pollen, parent. The new Hibiscus plant was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination in a controlled greenhouse environment in Alva, Fla. on Sep. 3, 2008.
Asexual reproduction of the new Hibiscus plant by vegetative terminal cuttings in a controlled greenhouse environment in Alva, Fla. since February, 2009 has shown that the unique features of this new Hibiscus plant 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 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 ‘Cayman Wind’. These characteristics in combination distinguish ‘Cayman Wind’ as a new and distinct Hibiscus plant:
- 1. Upright, somewhat outwardly spreading, uniformly mounded and dense plant habit appropriate for container production.
- 2. Glossy dark green-colored leaves.
- 3. Uniform, freely and early flowering habit.
- 4. Intense pink-colored flowers with dark red-colored centers.
- 5. Good postproduction and garden performance.
Plants of the new Hibiscus can be compared to plants of the female parent, ‘Captiva Wind’. Plants of the new Hibiscus differ from plants of ‘Captiva Wind’ in the following characteristics:
- 1. Plants of the new Hibiscus are more vigorous than plants of ‘Captiva Wind’.
- 2. Flowers of plants of the new Hibiscus are darker pink in color than flowers of plants of ‘Captiva Wind’.
Plants of the new Hibiscus can be compared to plants of the male parent selection. Plants of the new Hibiscus differ from plants of the male parent selection primarily in flower color as plants of the male parent selection have orange-colored flowers with red-colored centers.
Plants of the new Hibiscus can be compared to plants of the Hibiscus rosa-sinensis ‘Pink Versicolor’, not patented. In side-by-side comparisons conducted in Alva, Fla., plants of the new Hibiscus differed from plants of ‘Pink Versicolor’ in the following characteristics:
- 1. Plants of the new Hibiscus flowered later than plants of ‘Pink Versicolor’.
- 2. Plants of the new Hibiscus and ‘Pink Versicolor’ differed in flower color as plants of ‘Pink Versicolor’ had bright pink-colored flowers with dark pink-colored centers.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying colored photographs illustrate the overall appearance of the new Hibiscus 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 colors of the new Hibiscus plant.
The photograph on the first sheet comprises a side perspective view of typical flowering plants of ‘Cayman Wind’ grown in a container.
The photograph on the second sheet comprises a close-up view of a typical flowering plant of ‘Cayman Wind’.
DETAILED BOTANICAL DESCRIPTION
The aforementioned photographs and following observations, measurements and values describe plants grown during the summer in 15-cm containers in a fiberglass-covered greenhouse in Alva, Fla. and under environmental conditions and cultural practices which closely approximate commercial Hibiscus production. During the production of the plants, day temperatures ranged from 20° C. to 38° C., night temperatures ranged from 15° C. to 24° C. and light levels ranged from 3,000 to 4,000 foot-candles. Plants were pinched two times and were 24 weeks old when the photographs and the description were taken. In the description, color references are made to The Royal Horticultural Society Colour Chart, 2007 Edition, except where general terms of ordinary dictionary significance are used.
