Abstract

A new and distinct cultivar of Hibiscus plant named ‘Juno’, characterized by its upright, mounding and uniform plant habit; freely branching habit; dense and bushy appearance; glossy dark green-colored leaves; uniformly, freely and continuous flowering habit; dark red-colored flower buds; single flowers with imbricate red purple-colored petals and dark red-colored centers; and excellent flower longevity.

Description

Botanical designation: Hibiscus rosa-sinensis.
Cultivar denomination: ‘JUNO’.
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 ‘Juno’.
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 healthy and durable Hibiscus plants with attractive long-lasting flowers.
The new Hibiscus plant originated from a cross-pollination conducted by the Inventor in October, 2007 in Sabro, Denmark of a proprietary selection of Hibiscus rosa-sinensis identified as code number GB-2006-1386, not patented, as the female, or seed, parent with a proprietary selection of Hibiscus rosa-sinensis identified as code number GB 2006-5025, 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 August, 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 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 ‘Juno’. These characteristics in combination distinguish ‘Juno’ as a new and distinct Hibiscus plant:
    • 1. Upright, mounding and uniform plant habit.
    • 2. Freely branching habit; dense and bushy appearance.
    • 3. Glossy dark green-colored leaves.
    • 4. Uniformly, freely and continuous flowering habit.
    • 5. Dark red-colored flower buds.
    • 6. Single flowers with imbricate red purple-colored petals and dark red-colored centers.
    • 7. Excellent 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 flower color as plants of the female parent selection have red-colored flowers.
    • 2. Plants of the new Hibiscus and the female parent selection differ in flower shaped as plants of the female parent selection have funnelform flowers.
    • 3. Flowers of plants of the new Hibiscus last about three to five days longer than flowers of 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 and the male parent selection differ in flower color as plants of the male parent selection have apricot-colored flowers.
    • 2. Plants of the new Hibiscus and the male parent selection differ in flower shaped as plants of the male parent selection have flowers with non-imbricate petals.
    • 3. Flowers of plants of the new Hibiscus last about two to three days longer than flowers of plants of the male parent selection.
Plants of the new Hibiscus can be compared to plants of the Hibiscus rosa-sinensis ‘Adonis’, disclosed in U.S. Plant Pat. No. 21,592. In side-by-side comparisons conducted in Sabro, Denmark, plants of the new Hibiscus differed from plants of ‘Adonis’ in the following characteristics:
    • 1. Plants of the new Hibiscus had slightly smaller flowers than plants of ‘Adonis’.
    • 2. Plants of the new Hibiscus and ‘Adonis’ differed in flower bud and flower color as plants of ‘Adonis’ had lighter-colored flower buds and flowers.
    • 3. Flowers of plants of the new Hibiscus lasted about two to three days longer than flowers of plants of ‘Adonis’.
Plants of the new Hibiscus can be compared to plants of the Hibiscus rosa-sinensis ‘Boreas’, disclosed in U.S. Plant Pat. No. 21,618. In side-by-side comparisons conducted in Sabro, Denmark, plants of the new Hibiscus differed from plants of ‘Boreas’ in the following characteristics:
    • 1. Plants of the new Hibiscus had slightly smaller flowers than plants of ‘Boreas’.
    • 2. Plants of the new Hibiscus and ‘Boreas’ differed in flower color as plants of ‘Boreas’ had pale yellow-colored flowers.
    • 3. Flowers of plants of the new Hibiscus lasted about one to two days longer than flowers of plants of ‘Boreas’.
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 ‘Juno’ grown in a container.
The photograph on the second sheet is a close-up view of developing flower buds and an open flower of ‘Juno’.
The photograph on the third sheet is a close-up view of a dissected flower of ‘Juno’.
 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 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 eight 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.
