Abstract

A new and distinct cultivar of Hibiscus plant named ‘HIQ 1601’, characterized by its upright, mounding and bushy plant habit; dark green-colored leaves; uniform and freely flowering habit; large, rich yellow-colored flowers with orange red-colored centers; and excellent flower longevity.

Description

Botanical designation: Hibiscus rosa-sinensis.
Cultivar denomination: ‘HIQ 1601’.
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 ‘HIQ 1601’.
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 August, 2011 in Sabro, Denmark of a proprietary selection of Hibiscus rosa-sinensis identified as code designation GB 2010-0107, not patented, as the female, or seed, parent with a proprietary selection of Hibiscus rosa-sinensis identified as code designation GB 2010-3667, 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 May, 2012.
Asexual reproduction of the new Hibiscus plant by vegetative terminal cuttings in a controlled greenhouse environment in Sabro, Denmark since September, 2012 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 ‘HIQ 1601’. These characteristics in combination distinguish ‘HIQ 1601’ as a new and distinct Hibiscus plant:
    • 1. Upright, mounding and bushy plant habit.
    • 2. Dark green-colored leaves.
    • 3. Uniform and freely flowering habit.
    • 4. Large, rich yellow-colored flowers with orange red-colored centers.
    • 5. 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. Flowers of plants of the new Hibiscus are longer-lasting than flowers of plants of the female parent selection.
    • 2. Plants of the new Hibiscus have better garden performance 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. Leaves of plants of the new Hibiscus are glossier than leaves of plants of the male parent selection.
    • 2. Flowers of plants of the new Hibiscus are longer-lasting 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 Yellow’, disclosed in U.S. Plant Pat. No. 26,006. In side-by-side comparisons, plants of the new Hibiscus differ from plants of ‘Adonis Yellow’ in the following characteristics:
    • 1. Leaves of plants of the new Hibiscus are glossier than leaves of plants of ‘Adonis Yellow’.
    • 2. Plants of the new Hibiscus and ‘Adonis Yellow’ differ slightly in flower color as plants of ‘Adonis Yellow’ have lighter yellow-colored flowers.
    • 3. Plants of the new Hibiscus have better garden performance than plants of ‘Adonis Yellow’.
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 is a side perspective view of a typical flowering plant of ‘HIQ 1601’ 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 ‘HIQ 1601’.
The photograph on the third sheet is a close-up view of a typical dissected flower of ‘HIQ 1601’ showing the upper surfaces of the petals.
 DETAILED BOTANICAL DESCRIPTION
The aforementioned photographs and following observations, measurements and values describe plants grown during the autumn 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 nine weeks after planting and plants were 26 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.
