Abstract

A new and distinct cultivar of Hibiscus plant named ‘Apollo’, characterized by its upright to somewhat outwardly spreading plant form; dense and bushy plant habit; dark green-colored leaves; freely and continuous flowering habit; large yellow and orange-colored flowers with dark red-colored centers; good flower longevity; and good garden performance.

Description

Botanical designation: Hibiscus rosa-sinensis.
Cultivar denomination: ‘APOLLO’.
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 ‘Apollo’.
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 strong Hibiscus plants with attractive and long-lasting flowers.
The new Hibiscus plant originated from a cross-pollination 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 a proprietary selection of Hibiscus rosa-sinensis identified as code number GB 2006-5009, not patented, 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 April, 2008.
Asexual reproduction of the new Hibiscus plant by vegetative terminal cuttings in a controlled greenhouse environment in Sabro, Denmark since September, 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 environmental conditions. The phenotype may vary somewhat with variations in environment 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 ‘Apollo’. These characteristics in combination distinguish ‘Apollo’ as a new and distinct cultivar of Hibiscus plant:
    • 1. Upright to somewhat outwardly spreading plant form.
    • 2. Dense and bushy plant habit.
    • 3. Dark green-colored leaves.
    • 4. Freely and continuous flowering habit.
    • 5. Large yellow and orange-colored flowers with dark red-colored centers.
    • 6. Good flower longevity.
    • 7. Good garden performance.
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 flower color as flowers of plants of ‘Calypso Wind’ have dark orange-colored flowers with dark red-colored centers. In addition, leaves of plants of the new Hibiscus have irregularly serrate margins whereas leaves of plants ‘Calypso Wind’ have crenate margins.
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 flower longevity as flowers of plants of the new Hibiscus last about three to four days whereas flowers of plants of the male parent selection last about one or two days. In addition, plants of the new Hibiscus and the male parent selection differ in flower shape.
Plants of the new Hibiscus can be compared to plants of the Hibiscus rosa-sinensis ‘Cairo Apricot’, not patented. In side-by-side comparisons conducted in Sabro, Denmark, plants of the new Hibiscus differed from plants of ‘Cairo Apricot’ in the following characteristics:
    • 1. Plants of the new Hibiscus had broader flower buds than plants of ‘Cairo Apricot’.
    • 2. Flowers of plants of the new Hibiscus lasted about three to four days whereas flowers of plants of ‘Cairo Apricot’ lasted about one day.
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 ‘Apollo’ grown in a container.
The photograph on the second sheet are close-up views of typical developing flower buds and a fully opened flower of ‘Apollo’.
 DETAILED BOTANICAL DESCRIPTION
The aforementioned photographs and following observations, measurements and values describe plants grown during the summer in 13-cm containers in a glass-covered greenhouse in Sabro, Denmark and under conditions which closely approximate 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 seven weeks after planting and 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.
