plant named ‘Trinidad Wind’

Abstract

A new and distinct cultivar of Hibiscus plant named ‘Trinidad Wind’, characterized by its upright, somewhat outwardly spreading, uniformly mounded and dense plant habit appropriate for container production; glossy dark green-colored leaves; uniform, freely and early flowering habit; large bright red-colored flowers with dark red-colored centers; and good postproduction and garden performance.

Description

Botanical designation: Hibiscus rosa-sinensis.

Cultivar denomination: ‘TRINIDAD 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 ‘Trinidad 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 October, 2001 of a proprietary selection of Hibiscus rosa-sinensis identified as code number YB-1875, not patented, as the female, or seed, parent with a proprietary selection of Hibiscus rosa-sinensis identified as code number YB-2079, 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. 9, 2002.

Asexual reproduction of the new Hibiscus plant by vegetative terminal cuttings in a controlled greenhouse environment in Alva, Fla. since February, 2003 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 ‘Trinidad Wind’. These characteristics in combination distinguish ‘Trinidad 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. Large bright red-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 selection. Plants of the new Hibiscus differ from plants of the female parent selection in the following characteristics:

• • 1. Plants of the new Hibiscus are more outwardly spreading than plants of the female parent selection.
  • 2. Plants of the new Hibiscus have smaller flowers than plants of the female parent selection.
  • 3. Plants of the new Hibiscus and the female parent selection differ slightly in flower color as plants of the female parent selection have darker red-colored flower centers.

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 scarlet red-colored flowers with lighter red-colored centers.

Plants of the new Hibiscus can be compared to plants of the Hibiscus rosa-sinensis ‘Brilliant Red’, not patented. In side-by-side comparisons conducted in Alva, Fla., plants of the new Hibiscus differed from plants of ‘Brilliant Red’ in the following characteristics:

• • 1. Plants of the new Hibiscus were more upright than plants of ‘Brilliant Red’.
  • 2. Plants of the new Hibiscus were more freely branching than plants of ‘Brilliant Red’.
  • 3. Plants of the new Hibiscus had smaller flowers than plants of ‘Brilliant Red’.

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.

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 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 27 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.
