Abstract

A new and distinct cultivar of Hibiscus plant named ‘Multi Tropic Orange’, characterized by its upright, uniformly mounding and bushy plant habit; shiny dark green-colored leaves; uniform, continuous and freely flowering habit; bright orange-colored flowers with dark red-colored centers; and good flower longevity.

Description

Botanical designation: Hibiscus rosa-sinensis.
Cultivar denomination: ‘MULTI TROPIC ORANGE’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Hibiscus plant, botanically known as Hibiscus rosa-sinensis, and hereinafter referred to by the name ‘Multi Tropic Orange’.
The new Hibiscus plant is a product of a planned breeding program conducted by the Inventor in Sabro, Denmark. The objective of the breeding program is to create new compact, uniform, strong and freely-branching Hibiscus plants with continuous flowering and attractive long-lasting flowers.
The new Hibiscus plant originated from a cross-pollination conducted by the Inventor in April, 2007 in Sabro, Denmark of Hibiscus rosa-sinensis ‘Calypso Wind’, disclosed in U.S. Plant Pat. No. 10,947, as the female, or seed, parent with Hibiscus rosa-sinensis ‘Caroline’, disclosed in U.S. Plant Pat. No. 11,779, as the male, or pollen, parent. The new Hibiscus plant was discovered and selected by the Inventor as a flowering plant within the progeny of the stated cross-pollination in a controlled greenhouse environment in Sabro, Denmark in July, 2008.
Asexual reproduction of the new Hibiscus plant by vegetative terminal cuttings in a controlled greenhouse environment in Sabro, Denmark since October, 2008 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 ‘Multi Tropic Orange’. These characteristics in combination distinguish ‘Multi Tropic Orange’ as a new and distinct Hibiscus plant:
    • 1. Upright, uniformly mounding and bushy plant habit.
    • 2. Shiny dark green-colored leaves.
    • 3. Uniform, continuous and freely flowering habit.
    • 4. Bright orange-colored flowers with dark red-colored centers.
    • 5. Good flower longevity.
Plants of the new Hibiscus can be compared to plants of the female parent, ‘Calypso Wind’. Plants of the new Hibiscus differ primarily from plants of ‘Calypso Wind’ in the following characteristics:
    • 1. Plants of the new Hibiscus have smaller flowers than plants of ‘Calypso Wind’.
    • 2. Plants of the new Hibiscus and ‘Calypso Wind’ differ in flower color as plants of ‘Calypso Wind’ have lighter orange-colored flowers.
    • 3. Flowers of plants of the new Hibiscus are not as long-lasting as flowers of plants of ‘Calypso Wind’.
Plants of the new Hibiscus can be compared to plants of the male parent, ‘Caroline’. Plants of the new Hibiscus differ primarily from plants of ‘Caroline’ in the following characteristics:
    • 1. Plants of the new Hibiscus and ‘Caroline’ differ in leaf shape.
    • 2. Plants of the new Hibiscus and ‘Caroline’ differ in flower color as plants of ‘Caroline’ have lighter orange-colored flowers.
    • 3. Flowers of plants of the new Hibiscus are longer-lasting than flowers of ‘Caroline’.
Plants of the new Hibiscus can be compared to plants of the Hibiscus rosa-sinensis ‘Laluna’, disclosed in U.S. Plant Pat. No. 24,061. In side-by-side comparisons conducted in Sabro, Denmark, plants of the new Hibiscus differed from plants of ‘Laluna’ in the following characteristics:
    • 1. Plants of the new Hibiscus and ‘Laluna’ differed slightly in leaf shape.
    • 2. Plants of the new Hibiscus and ‘Laluna’ differed in flower form as plants of ‘Laluna’ had double-type flowers.
    • 3. Plants of the new Hibiscus and ‘Laluna’ differed in flower color as plants of ‘Laluna’ had lighter orange-colored flowers.
    • 4. Flowers of plants of the new Hibiscus were not as long- lasting as flowers of plants of ‘Laluna’.
Plants of the new Hibiscus can be compared to plants of the Hibiscus rosa-sinensis ‘Apollo’, disclosed in U.S. Plant Pat. No. 23,072. In side-by-side comparisons conducted in Sabro, Denmark, plants of the new Hibiscus differed from plants of ‘Apollo’ in the following characteristics:
    • 1. Plants of the new Hibiscus and ‘Apollo’ differed in leaf shape.
    • 2. Plants of the new Hibiscus had smaller flowers than plants of ‘Apollo’.
    • 3. Plants of the new Hibiscus and ‘Apollo’ differed in flower color.
    • 4. Flowers of plants of the new Hibiscus were not as long-lasting as flowers of plants of ‘Apollo’.
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 a typical flowering plant of ‘Multi Tropic Orange’ grown in a container.
The photograph on the second sheet is a close-up view of typical developing flower buds and a typical open flower of ‘Multi Tropic Orange’.
 DETAILED BOTANICAL DESCRIPTION
The aforementioned photographs and following observations, measurements and values describe plants grown during the autumn and winter in 13-cm containers in a glass-covered greenhouse in Sabro, Denmark and under cultural practices typical of commercial Hibiscus production. During the production of the plants, day temperatures ranged from 20° C. to 25° C., night temperatures ranged from 19° C. to 21° C. and light levels ranged from 40 to 50 klux. Plants were pinched one time about nine to ten weeks after planting. Plants 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, 2001 Edition, except where general terms of ordinary dictionary significance are used.
