Abstract

A new and distinct cultivar of Hibiscus plant named ‘Oak Red’, characterized by its upright, somewhat, outwardly spreading and dense and bushy plant habit; dark green-colored oakleaf-shaped leaves; freely flowering habit; large red-colored flowers; and good flower longevity.

Description

Botanical designation: Hibiscus hybrida.
Cultivar denomination: ‘OAK RED’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Hibiscus plant, botanically known as Hibiscus hybrida, and hereinafter referred to by the name ‘Oak Red’.
The new Hibiscus plant is a product of a planned breeding program conducted by the Inventor in Herenthout, Belgium. The objective of the breeding program is to create new compact Hibiscus plants with attractive and large flowers.
The new Hibiscus plant originated from a cross-pollination in August, 2005 in Herenthout, Belgium of an unnamed proprietary seedling selection of Hibiscus hybrida, not patented, as the female, or seed, parent with an unnamed proprietary seedling selection of Hibiscus coccineus 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 Herenthout, Belgium in July, 2006.
Asexual reproduction of the new Hibiscus plant by vegetative terminal cuttings in a controlled greenhouse environment in Herenthout, Belgium since August, 2006, 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 and cultural practices 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 ‘Oak Red’. These characteristics in combination distinguish ‘Oak Red’ as a new and distinct cultivar of Hibiscus:
    • 1. Upright, somewhat, outwardly spreading and dense and bushy plant habit.
    • 2. Dark green-colored oakleaf-shaped leaves.
    • 3. Freely flowering habit.
    • 4. Large red-colored flowers.
    • 5. Good flower longevity.
Plants of the new Hibiscus can be compared to plants of the parent selections. Plants of the new Hibiscus differ primarily from plants of the parent selections in flower size and color.
Plants of the new Hibiscus can be compared to plants of the Hibiscus moscheutos ‘Mauvelous’, not patented. Plants of the new Hibiscus differ from plants of ‘Mauvelous’ in the following characteristics:
    • 1. Plants of the new Hibiscus are more compact, uniform and outwardly spreading than plants of ‘Mauvelous’.
    • 2. Plants of the new Hibiscus have oakleaf-shaped leaves whereas plants of ‘Mauvelous’ have oval-shaped leaves.
    • 3. Flowers of plants of the new Hibiscus and ‘Mauvelous’ differ in color as plants of ‘Mauvelous’ have pink-colored flowers.
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 ‘Oak Red’ grown in a container.
The photograph on the second sheet is a close-up view of a typical flower of ‘Oak Red’.
 DETAILED BOTANICAL DESCRIPTION
The aforementioned photographs and following observations, measurements and values describe plants grown in De Kwakel, The Netherlands in five-liter containers in a glass-covered greenhouses during the summer under conditions which closely approximate commercial Hibiscus production. During the production of the plants, day temperatures ranged from 18° C. to 33° C. and night temperatures ranged from 15° C. to 25° C. Plants were 16 weeks 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.
