Abstract
A new and distinct Hibiscus plant named ‘Denver’, characterized by its compact, upright and uniform plant habit that is appropriate for container production; freely branching habit; glossy medium green-colored leaves; freely and continuous flowering habit; orange and red bi-colored flowers; and good resistance to flower bud abscission.
Description
Botanical classification/cultivar designation: Hibiscus rosa-sinensis cultivar Denver.
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 ‘Denver’.
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 cultivars appropriate for container production.
The new Hibiscus originated from a cross-pollination made by the Inventor in Amstelveen, The Netherlands in 1999, of a proprietary Hibiscus rosa-sinensis selection, identified as code number 239.2317, not patented, as the female, or seed, parent with a proprietary Hibiscus rosa-sinensis selection, designated as code number 5.17.14816, not patented, as the male, or pollen, parent. The cultivar Denver was discovered and selected by the Inventor as a flowering plant within the progeny of the stated cross-pollination in a controlled environment in Amstelveen, The Netherlands, in 2000.
Asexual reproduction of the new Hibiscus by vegetative terminal cuttings in a controlled environment in Amstelveen, The Netherlands since 2000, has shown that the unique features of this new Hibiscus are stable and reproduced true to type in successive generations.
The cultivar Denver 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 variance in genotype.
The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Denver’. These characteristics in combination distinguish ‘Denver’ as a new and distinct cultivar:
-
- 1. Compact, upright and uniform plant habit that is appropriate for container production.
- 2. Freely branching habit.
- 3. Glossy medium green-colored leaves.
- 4. Freely and continuous flowering habit.
- 5. Orange and red bi-colored flowers.
- 6. Good resistance to flower bud abscission.
Compared to plants of the parents, the proprietary Hibiscus selections, plants of the new Hibiscus are more upright, more freely branching, and more freely flowering.
Plants of the new Hibiscus are similar to plants of the Hibiscus cultivar Hanne, not patented. However, in side-by-side comparisons conducted in Amstelveen, The Netherlands, plants of the new Hibiscus differed from plants of the cultivar Hanne in the following characteristics:
-
- 1. Plants of the new Hibiscus were shorter than plants of the cultivar Hanne.
- 2. Plants of the new Hibiscus were more upright and more rounded than plants of the cultivar Hanne.
- 3. Leaves of plants of the new Hibiscus were longer and narrower than leaves of plants of the cultivar Hanne.
- 4. Plants of the new Hibiscus had larger flowers than plants of the cultivar Hanne.
- 5. Plants of the new Hibiscus were more freely flowering than plants of the cultivar Hanne.
- 6. Flowers of plants of the new Hibiscus were more red in color than flowers of plants of the cultivar Hanne.
- 7. Flower peduncles of plants of the new Hibiscus were longer and thicker than flower peduncles of plants of the cultivar Hanne.
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 slightly from 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 ‘Denver’ grown in a container.
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 closely approximate commercial production. During the production of the plants, day and night temperatures ranged from 15 to 25° C. and light levels were about 500 kilolux. Plants were about two years old when the photograph and the description were taken. In the description, color references are made to The Royal Horticultural Society Colour Chart, 1986 Edition, except where general terms of ordinary dictionary significance are used.
