| Abstract: |
A new and distinct cultivar of Hibiscus plant named `HJ-117`, characterized by its upright and somewhat outwardly spreading plant habit; freely branching habit when pinched; relatively large leaves; large yellow-colored flowers with white-colored centers; and long flower longevity. |
| Claim: |
It is claimed:
1. A new and distinct Hibiscus plant named `HJ-117` as illustrated and described. |
| Description: |
Botanical designation: Hibiscusrosa-sinensis.
Cultivar denomination: `HJ-117`.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Hibiscus, botanically known as Hibiscus rosa-sinensis, and hereinafter referred to by the name `HJ-117`.
The new Hibiscus is a product of a planned breeding program conducted by the Inventor in Seaforth, Ontario, Canada. The objective of the breeding program is to create new Hibiscus cultivars that flower early and have long flower longevity.
The new Hibiscus originated from a cross-pollination made by the Inventor in Seaforth, Ontario, Canada in November, 2002, of the Hibiscus rosa-sinensis cultivar Byron Metts, not patented, as the female, or seed, parent with a proprietary Hibiscusrosa-sinensis selection, designated as code number HJ-136, not patented, as the male, or pollen, parent. The cultivar HJ-117 was discovered and selected by the Inventor as a flowering plant within the progeny of the stated cross-pollination in acontrolled environment in Seaforth, Ontario, Canada in October, 2003.
Asexual reproduction of the new Hibiscus by vegetative terminal cuttings in a controlled environment in Seaforth, Ontario, Canada since January, 2004, has shown that the unique features of this new Hibiscus are stable and reproduced true to typein successive generations.
SUMMARY OF THE INVENTION
The cultivar HJ-117 has 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 variancein genotype.
The following traits have been repeatedly observed and are determined to be the unique characteristics of `HJ-117`. These characteristics in combination distinguish `HJ-117` as a new and distinct cultivar of Hibiscus: 1. Upright and somewhatoutwardly spreading plant habit. 2. Freely branching habit when pinched. 3. Relatively large leaves. 4. Large yellow-colored flowers with white-colored centers. 5. Long flower longevity.
Plants of the new Hibiscus can be compared to plants of the female parent, the cultivar Byron Metts. Plants of the new Hibiscus differ from plants of the cultivar Byron Metts in the following characteristics: 1. Plants of the new Hibiscus havesmaller and lighter green-colored leaves than plants of the cultivar Byron Metts. 2. Plants of the new Hibiscus have smaller flowers than plants of the cultivar Byron Metts. 3. Plants of the new Hibiscus and the cultivar Byron Metts differ in flowercoloration as plants of the cultivar Byron Metts have solid white-colored flowers.
Plants of the new Hibiscus can be compared to plants of the male parent, the proprietary Hibiscus selection identified as code number HJ-136. Plants of the new Hibiscus differ from plants of the male parent selection in the followingcharacteristics: 1. Plants of the new Hibiscus have smaller leaves than plants of the male parent selection. 2. Plants of the new Hibiscus and the male parent selection differ in flower coloration as plants of the male parent selection have white andpurple-colored flowers. 3. Plants of the new Hibiscus have longer lasting flowers than plants of the male parent selection. 4. Plants of the new Hibiscus root more easily than plants of the male parent selection.
Plants of the new Hibiscus can be compared to plants of the Hibiscus rosa-sinensis cultivar Coconut Cream, not patented. In side-by-side comparisons conducted in Seaforth, Ontario, Canada, plants of the new Hibiscus differed from plants of thecultivar Coconut Cream in the following characteristics: 1. Plants of the new Hibiscus had darker green-colored leaves than plants of the cultivar Coconut Cream. 2. Plants of the new Hibiscus were more freely branching than plants of the cultivarCoconut Cream. 3. Plants of the new Hibiscus had longer lasting flowers than plants of the cultivar Coconut Cream. 4. Plants of the new Hibiscus rooted more easily than plants of the cultivar Coconut Cream.
Plants of the new Hibiscus can be compared to plants of the Hibiscus rosa-sinensis cultivar HJ-116, disclosed in U.S. Plant Pat. No. 18,586. In side-by-side comparisons conducted in Seaforth, Ontario, Canada, plants of the new Hibiscusdiffered from plants of the cultivar HJ-116 in the following characteristics: 1. Plants of the new Hibiscus had longer lateral branches and internodes than plants of the cultivar HJ-116. 2. Plants of the new Hibiscus had smaller flowers than plants ofthe cultivar HJ-116. 3. Plants of the new Hibiscus and the cultivar HJ-116 differed in flower color. 4. Plants of the new Hibiscus had longer peduncles than plants of the cultivar HJ-116.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying colored photographs illustrate the overall appearance of the new Hibiscus, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightlyfrom the color values cited in the detailed botanical description which accurately describe the colors of the new Hibiscus.
The photograph on the first sheet comprises a side perspective view of typical flowering plants of `HJ-117` grown in a container.
The photograph on the second sheet is a close-up view of a typical flower of `HJ-117`.
DETAILED BOTANICAL DESCRIPTION
The aforementioned photographs and following observations, measurements and values describe plants grown in Seaforth, Ontario, Canada in containers during the winter and spring in polyethylene-covered greenhouses under conditions which closelyapproximate commercial production.
