Abstract
A new and distinct cultivar of Hibiscus plant named ‘Dohibcarbre’, characterized by its upright and mounding plant habit; moderately vigorous growth habit and moderate growth rate; freely branching habit; dense and bushy appearance; dark green-colored leaves; freely flowering habit; large double, reddish orange-colored flowers; and good container and garden performance and high temperature tolerance.
Description

Botanical designation: Hibiscus rosa-sinensis.


Cultivar denomination: ‘DOHIBCARBRE’.


STATEMENT REGARDING PRIOR DISCLOSURES BY INVENTOR and APPLICANT/ASSIGNEE

The Inventor and Applicant/Assignee assert that no sales, offers for sale or public distribution of the instant plant occurred more than one year prior to the effective filing date of this application. Any information about the claimed plant would have been obtained from a direct or indirect disclosure from the Inventor and/or Applicant/Assignee. Inventor and Applicant/Assignee claim a prior art exception under 35 U.S.C. 102 (b) (1) for disclosures and/or sales prior to the filing date but less than one year prior to the effective filing date.


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 ‘Dohibcarbre’.


The new Hibiscus plant is a product of a planned breeding program conducted by the Inventor in De Lier, The Netherlands and Puerto Lumbreras, Murcia, Spain. The objective of the breeding program is to create new freely-branching Hibiscus plants with large attractive flowers and high temperature tolerance.


The new Hibiscus plant originated from a cross-pollination during the summer of 2019 in De Lier, The Netherlands of a proprietary selection of Hibiscus rosa-sinensis identified as code number HI-0027, not patented, as the female, or seed, parent with a proprietary selection of Hibiscus rosa-sinensis identified as code number HI-0017, 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 Puerto Lumbreras, Murcia, Spain during the summer of 2020.


Asexual reproduction of the new Hibiscus plant by vegetative terminal cuttings in a controlled greenhouse environment in Puerto Lumbreras, Spain since the summer of 2020 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 ‘Dohibcarbre’. These characteristics in combination distinguish ‘Dohibcarbre’ as a new and distinct Hibiscus plant:

    • 1. Upright and mounding plant habit.
    • 2. Moderately vigorous growth habit and moderate growth rate.
    • 3. Freely branching habit; dense and bushy appearance.
    • 4. Dark green-colored leaves.
    • 5. Freely flowering habit.
    • 6. Large double, reddish orange-colored flowers.
    • 7. Good container and garden performance with high temperature tolerance.


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 are not as vigorous as plants of the female parent selection.
    • 2. Flowers of plants of the new Hibiscus are double-types whereas flowers of plants of the female parent selection are single-types.
    • 3. Plants of the new Hibiscus are more high temperature tolerant than plants of the female parent selection.


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 the following characteristics:

    • 1. Plants of the new Hibiscus are more freely branching than plants of the male parent selection.
    • 2. Plants of the new Hibiscus have larger leaves than plants of the male parent selection.
    • 3. Plants of the new Hibiscus have smaller flowers than plants of the male parent selection.
    • 4. Plants of the new Hibiscus are more high temperature tolerant than plants of the male parent selection.


Plants of the new Hibiscus can be compared to plants of the Hibiscus rosa-sinensis ‘Adonicus Double Orange’, not patented. In side-by-side comparisons, plants of the new Hibiscus differ from plants of ‘Adonicus Double Orange’ in the following characteristics:

    • 1. Plants of the new Hibiscus are shorter than plants of ‘Adonicus Double Orange’.
    • 2. Plants of the new Hibiscus have shorter internodes than plants of ‘Adonicus Double Orange’.
    • 3. Plants of the new Hibiscus are more freely branching than plants of ‘Adonicus Double Orange’.
    • 4. Leaves of plants of the new Hibiscus are larger and stronger than leaves of plants of ‘Adonicus Double Orange’.
    • 5. Plants of the new Hibiscus are more freely flowering than plants of ‘Adonicus Double Orange’.
    • 6. Flowers of plants of the new Hibiscus are darker reddish orange in color than flowers of plants of ‘Adonicus Double Orange’.
    • 7. Plants of the new Hibiscus are more high temperature tolerant than plants of ‘Adonicus Double Orange’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown during the summer in 15-cm containers in a glass-covered greenhouse in De Lier, The Netherlands and under cultural practices typical of commercial Hibiscus production. During the production of the plants, day temperatures ranged from 20° C. to 35° C., night temperatures ranged from 17° C. to 25° C. and light levels were at least 135 watt/m2. Plants were pinched one time four weeks after planting and a second time twelve 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, Fifth Edition, except where general terms of ordinary dictionary significance are used.
