plant named ‘Hot Pink Wind’

Abstract

A new and distinct cultivar of Hibiscus plant named ‘Hot Pink Wind’, characterized by its upright to outwardly spreading and 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; and large bright purplish red-colored flowers with small dark red-colored throats.

Description

Botanical designation: Hibiscus rosa-sinensis.

Cultivar denomination: ‘HOT PINK 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 ‘Hot Pink Wind’.

The new Hibiscus plant is a product of a planned breeding program conducted by the Inventor in Alva, Florida. The objective of the breeding program is to create new freely-branching Hibiscus plants with uniform plant habit appropriate for container production, early and freely flowering habit, and large attractive flowers.

The new Hibiscus plant originated from a cross-pollination made by the Inventor in Alva, Florida in 2022 of Hibiscus rosa-sinensis ‘Cayman Wind’, disclosed in U.S. Plant Pat. No. 23,760, as the female, or seed, parent with Hibiscus rosa-sinensis ‘Yellow Lava Wind’, disclosed in U.S. Plant patent application Ser. No. 18/395,598 (abandoned), 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, Florida on Jan. 9, 2023.

Asexual reproduction of the new Hibiscus plant by vegetative terminal cuttings in a controlled greenhouse environment in Alva, Florida since April, 2023 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 ‘Hot Pink Wind’. These characteristics in combination distinguish ‘Hot Pink Wind’ as a new and distinct Hibiscus plant:

• • 1. Upright to outwardly spreading and 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 purplish red-colored flowers with small dark red-colored throats.

Plants of the new Hibiscus can be compared to plants of the female parent, ‘Cayman Wind’. Plants of the new Hibiscus differ primarily from plants of ‘Cayman Wind’ primarily in flower color as flowers of the new Hibiscus have smaller dark red-colored throats than flowers of plants of ‘Cayman Wind’. In addition, plants of the new Hibiscus are more upright than and not as outwardly spreading as plants of ‘Cayman Wind’.

Plants of the new Hibiscus can be compared to plants of the male parent, ‘Yellow Lava Wind’. Plants of the new Hibiscus differ primarily from plants of ‘Yellow Lava Wind’ primarily in flower color as flowers of the new Hibiscus are bright purplish red in color whereas flowers of plants of ‘Yellow Lava Wind’ are golden yellow in color. In addition, flowers of plants of the new Hibiscus have smaller dark red-colored throats than flowers of plants of ‘Yellow Lava Wind’.

Plants of the new Hibiscus can be compared to plants of the Hibiscus rosa-sinensis ‘Pink Flamingo Wind’, disclosed in U.S. Plant Pat. No. 35,220. In side-by-side comparisons plants of the new Hibiscus differ from plants of ‘Pink Flamingo Wind’ in the following characteristics:

• • 1. Plants of the new Hibiscus have larger flowers than plants of ‘Pink Flamingo Wind’.
  • 2. Flowers of plants of the new Hibiscus are lighter in color than flowers of plants of ‘Pink Flamingo Wind’.
  • 3. Flowers of plants of the new Hibiscus have smaller dark red-colored throats than flowers of plants of ‘Pink Flamingo 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 (FIG. 1) is a side perspective view of a typical flowering plant of ‘Hot Pink Wind’ grown in a container.

The photograph on the second sheet (FIG. 2) is a close-up view of a typical flower of ‘Hot Pink Wind’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown during the autumn and winter in 15-cm containers in a polyethylene-covered greenhouse in Alva, Florida under cultural practices which closely approximate commercial Hibiscus production. During the production of the plants, day temperatures averaged 28° C., night temperatures averaged 18° C. and light levels ranged from 4,000 to 5,000 foot-candles. Plants were pinched two times and were seven months old when the photographs and the description were taken. In the description, color references are made to The Royal Horticultural Society Colour Chart, 2015 Edition, except where general terms of ordinary dictionary significance are used.
