Abstract

A new and distinct cultivar of Hibiscus plant named ‘JWNWOOD 4’, characterized by its upright and outwardly spreading plant habit; vigorous growth habit; freely branching habit; large light pink-colored flowers with numerous petaloids; and good garden performance.

Description

Botanical designation: Hibiscus syriacus.

Cultivar denomination: ‘JWNWOOD 4’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Hibiscus, botanically known as Hibiscus syriacus, commercially known as Rose-of-Sharon or Althea, and hereinafter referred to by the name ‘JWNWOOD 4’.

The new Hibiscus plant is a product of a planned breeding program conducted by the Inventor in Runcton Holme, Norfolk, United Kingdom. The objective of the breeding program was to develop new Hibiscus plants with large pink-colored flowers.

The new Hibiscus plant originated from a cross-pollination conducted by the Inventor in July, 2003 of a proprietary selection of Hibiscus syriacus identified as code number 3311, not patented, as the female, or seed, parent with a proprietary selection of Hibiscus syriacus identified as code number 4243, not patented, as the male, or pollen, parent. The new Hibiscus plant was discovered and selected by the Inventor on Sep. 4, 2006 as a single flowering plant within the progeny of the stated cross-pollination in a controlled outdoor nursery environment in Runction Holme, Norfolk, United Kingdom.

Asexual reproduction of the new Hibiscus plant by softwood cuttings in a controlled greenhouse environment in Runcton Holme, Norfolk, United Kingdom has shown that the unique features of this new Hibiscus plant are stable and reproduced true to type in successive generations of asexual reproduction.

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 ‘JWNWOOD 4’. These characteristics in combination distinguish ‘JWNWOOD 4’ as a new and distinct Hibiscus plant:

    • 1. Upright and outwardly spreading plant habit.
    • 2. Vigorous growth habit.
    • 3. Freely branching habit.
    • 4. Large light pink-colored flowers with numerous petaloids.
    • 5. Good garden performance.

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 flower color and flower form as plants of the female parent selection have white-colored flowers with fewer petaloids.

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 color and flower form as plants of the male parent selection have white-colored flowers with fewer petaloids.

Plants of the new Hibiscus can be compared to plants of the Hibiscus syriacus ‘Notwood3’, disclosed in U.S. Plant Pat. No. 20,574. In side-by-side comparisons conducted in Grand Haven, Mich., plants of the new Hibiscus differed from plants of ‘Notwood3’ primarily in flower color as plants of ‘Notwood3’ had blue-colored flowers. In addition, plants of the new Hibiscus were not as vigorous as plants of ‘Notwood3’.

Plants of the new Hibiscus can also be compared to plants of the Hibiscus syriacus ‘Notwoodtwo’, disclosed in U.S. Plant Pat. No. 12,612. In side-by-side comparisons conducted in Grand Haven, Mich., plants of the new Hibiscus differed from plants of ‘Notwoodtwo’ primarily in flower color as plants of ‘Notwoodtwo’ had white-colored flowers. In addition, plants of the new Hibiscus were not as vigorous as plants of ‘Notwoodtwo’.

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 plant of ‘JWNWOOD 4’ grown in a ground bed in an outdoor nursery.

The photograph on the second sheet is a close-up view of typical flowering plant of ‘JWNWOOD 4’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown in Grand Haven, Mich. during the summer in a ground bed in an outdoor nursery and under cultural conditions which closely approximate commercial Hibiscus production. Plants were three years old when the photographs and the description were taken. In the following detailed description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
