Abstract

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

Description

Botanical designation: Hibiscus rosa-sinensis.
Cultivar denomination: ‘MULTI TROPIC YELLOW’.
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 Yellow’.
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 an open-pollination in September, 2006 in Sabro, Denmark of a proprietary selection of Hibiscus rosa-sinensis identified as code number GB 2006-0027, not patented, as the female, or seed, parent with an unknown selection of Hibiscus rosa-sinensis 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 open-pollination in a controlled greenhouse environment in Sabro, Denmark in August, 2007.
Asexual reproduction of the new Hibiscus plant by vegetative terminal cuttings in a controlled greenhouse environment in Sabro, Denmark since October, 2007 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 Yellow’. These characteristics in combination distinguish ‘Multi Tropic Yellow’ 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 yellow-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 selection. Plants of the new Hibiscus differ primarily from plants of the female parent selection in the following characteristics:
    • 1. Plants of the new Hibiscus and the female parent selection differ in leaf shape.
    • 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.
    • 4. Flowers of plants of the new Hibiscus are not as long-lasting as flowers of plants of the female parent selection.
Plants of the new Hibiscus can be compared to plants of the Hibiscus rosa-sinensis ‘Boreas Yellow’, disclosed in U.S. Plant Pat. No. 24,060. In side-by-side comparisons conducted in Sabro, Denmark, plants of the new Hibiscus differed from plants of ‘Boreas Yellow’ in the following characteristics:
    • 1. Plants of the new Hibiscus and ‘Boreas Yellow’ differed in leaf color and shape.
    • 2. Plants of the new Hibiscus had smaller flowers than plants of ‘Boreas Yellow’.
    • 3. Plants of the new Hibiscus and Boreas Yellow' differed slightly in flower color.
    • 4. Flowers of plants of the new Hibiscus were not as long-lasting as flowers of plants of ‘Boreas Yellow’.
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 color and 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 as plants of ‘Apollo’ had orange and yellow-colored flowers.
    • 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 Yellow’ 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 Yellow’.
 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 25 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.
