Abstract

A new and distinct cultivar of Hibiscus plant named ‘Fire Wind’, characterized by its semi-upright, uniformly mounded plant habit appropriate for container production; freely branching habit, dense and bushy appearance; 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: ‘FIRE 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 ‘Fire 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 2009 of Hibiscus rosa-sinensis ‘Largo Breeze’, disclosed in U.S. Plant Pat. No. 12,869, as the female, or seed, parent with a proprietary selection of Hibiscus rosa-sinensis identified as code number 2691, 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 Jul. 16, 2012.

Asexual reproduction of the new Hibiscus plant by vegetative terminal cuttings in a controlled greenhouse environment in Alva, Fla. since September, 2012 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 combinations of 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 ‘Fire Wind’. These characteristics in combination distinguish ‘Fire Wind’ as a new and distinct Hibiscus plant:

• • 1. Semi-upright, uniformly mounded plant habit appropriate for container production.
  • 2. Freely branching habit, dense and bushy appearance.
  • 3. Glossy dark green-colored leaves.
  • 4. Uniform, freely and early flowering habit.
  • 5. Large bright red-colored flowers with dark red-colored centers.
  • 6. Good postproduction and garden performance.

Plants of the new Hibiscus can be compared to plants of the female parent, ‘Largo Breeze’. Plants of the new Hibiscus differ primarily from plants of ‘Largo Breeze’ in the following characteristics:

• • 1. Plants of the new Hibiscus are more uniform in plant habit than plants of ‘Largo Breeze’.
  • 2. Plants of the new Hibiscus are more uniform in flowering habit than plants of ‘Largo Breeze’.
  • 3. Plants of the new Hibiscus and ‘Largo Breeze’ differ in flower color as plants of ‘Largo Breeze’ have orange-colored flowers.

Plants of the new Hibiscus can be compared to plants of the male parent selection. Plants of the new Hibiscus differ primarily from plants of the male parent selection in the following characteristics:

• • 1. Plants of the new Hibiscus are more upright than and not as outwardly spreading as plants of the male parent selection.
  • 2. Plants of the new Hibiscus are more freely flowering than plants of the male parent selection.

Plants of the new Hibiscus can be compared to plants of the Hibiscus rosa-sinensis ‘Antigua Wind’, disclosed in U.S. Plant Pat. No. 23,656. In side-by-side comparisons plants of the new Hibiscus differ from plants of ‘Antigua Wind’ in the following characteristics:

• • 1. Plants of the new Hibiscus are more vigorous than plants of ‘Antigua Wind’.
  • 2. Plants of the new Hibiscus are more uniform in plant habit than plants of ‘Antigua Wind’.

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 ‘Fire Wind’ grown in a container.

The photograph on the second sheet comprises a close-up view of a typical flowering plant of ‘Fire Wind’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown during the summer in 20-cm containers in a polyethylene-covered greenhouse in Alva, Fla. and in an outdoor nursery in Fort Worth, Tex. under cultural practices which closely approximate commercial Hibiscus production. During the production of the plants, day temperatures ranged from 21° C. to 35° C., night temperatures ranged from 12° C. to 21° C. and light levels ranged from 5,000 to 8,000 foot-candles. Plants were pinched three times and were ten months 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.
