| Abstract: |
A new and distinct Hibiscus plant named `Charleston`, characterized by its compact, upright and uniform plant habit that is appropriate for container production; freely branching habit; glossy dark green leaves; freely flowering habit; red-colored flowers; and good resistance to flower bud abscission. |
| Claim: |
It is claimed:
1. A new and distinct Hibiscus plant named `Charleston`, as illustrated and described. |
| Description: |
Botanicalclassification/cultivar designation: Hibiscus rosa-sinensis cultivar `Charleston`.
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 `Charleston`.
The new Hibiscus is a product of a planned breeding program conducted by the Inventor in Amstelveen, The Netherlands. The objective of the breeding program is to create new compact freely-branching and freely-flowering Hibiscus cultivarsappropriate for container production.
The new Hibiscus originated from a cross-pollination made by the Inventor in Amstelveen, The Netherlands, of a proprietary Hibiscus rosa-sinensis selection, identified as code No. 10.327, not patented, as the female, or seed, parent with aproprietary Hibiscus rosa-sinensis selection, designated as code No. 5.923, not patented, as the male, or pollen, parent. The cultivar Charleston was discovered and selected by the Inventor as a flowering plant within the progeny of the statedcross-pollination in a controlled environment in Amstelveen, The Netherlands, in 2000.
Asexual reproduction of the new Hibiscus by vegetative terminal cuttings taken in a controlled environment in Amstelveen, The Netherlands, has shown that the unique features of this new Hibiscus are stable and reproduced true to type insuccessive generations.
SUMMARY OF THE INVENTION
The cultivar Charleston 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, anyvariance in genotype.
The following traits have been repeatedly observed and are determined to be the unique characteristics of `Charleston`. These characteristics in combination distinguish `Charleston` as a new and distinct cultivar: 1. Compact, upright anduniform plant habit that is appropriate for container production. 2. Freely branching habit. 3. Glossy dark green leaves. 4. Freely flowering habit. 5. Red-colored flowers. 6. Good resistance to flower bud abscission.
Compared to plants of the parents, the proprietary Hibiscus selections code No. 10.327 and 5.923, plants of the new Hibiscus are more upright, more freely branching, and more freely flowering.
Plants of the new Hibiscus can be compared to plants of the Hibiscus cultivar `Paramaribo`, not patented. In side-by-side comparisons conducted in Amstelveen, The Netherlands, plants of the new Hibiscus differed from plants of the cultivarParamaribo in the following characteristics: 1. Plants of the new Hibiscus were more vigorous, shorter, and broader than plants of the cultivar Paramaribo. 2. Plants of the new Hibiscus were more freely flowering than plants of the cultivarParamaribo. 3. Plants of the new Hibiscus had larger flowers than plants of the cultivar Paramaribo. 4. Flower color of plants of the new Hibiscus was more intense red than flower color of plants of the cultivar Paramaribo.
BRIEF DESCRIPTIONOF THE PHOTOGRAPH
The accompanying colored photograph illustrates 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 photograph may differ slightlyfrom the color values cited in the detailed botanical description which accurately describe the colors of the new Hibiscus. The photograph comprises a side perspective view of a typical flowering plant of `Charleston` grown in a container.
DETAILED BOTANICAL DESCRIPTION
The aforementioned photograph and following observations and measurements describe plants grown in Amstelveen, The Netherlands, grown in 15-cm container in a glass-covered greenhouse during the spring and summer under conditions which closelyapproximate commercial production. During the production of the plants, day and night temperatures ranged from 15 to 25.degree. C. and light levels were about 500 klux. Plants were about two years old when the photograph and the description weretaken. In the description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
