Gazania plant named ‘California Gold’
A new and distinct cultivar of Gazania named ‘California Gold’, characterized by its compact, low-growing and bushy growth habit; upright, outwardly spreading and rounded plant form; freely-flowering habit; large fully inflorescences with yellow and orange bi-colored ray florets; and relatively less susceptible to fungal pathogens common to Gazanias.
Botanical classification/cultivar designation: Gazania rigens cultivar California Gold.
BACKGROUND OF THE INVENTIONThe present invention relates to a new and distinct cultivar of Gazania plant, botanically known as Gazania rigens and referred to by the name ‘California Gold’.
The new Gazania is a product of a planned breeding program conducted by the Inventor in Ontario, Calif. The objective of the program is to create and develop new Gazania cultivars with a compact growth habit and numerous inflorescences with attractive ray floret coloration.
The new Gazania originated from a cross-pollination of two unknown selections of Gazania rigens, not patented. The new Gazania was discovered and selected by the Inventor as a plant within the progeny of the stated cross-pollination in a controlled environment in Ontario, Calif. in March, 2000.
Asexual reproduction of the new Gazania by terminal cuttings in a controlled environment in Ontario, Calif. since April, 2000, has shown that the unique features of this new Gazania are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTIONThe new Gazania has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and light intensity without, however, any variance in genotype.
The following characteristics have been repeatedly observed and are determined to be basic characteristics of ‘California Gold’ and distinguish the new Gazania as a new and distinct cultivar:
-
- 1. Compact, low-growing and bushy growth habit.
- 2. Upright, outwardly spreading and rounded plant form.
- 3. Freely-flowering habit.
- 4. Large fully inflorescences with yellow and orange bi-colored ray florets.
- 5. Relatively less susceptible to fungal pathogens common to Gazanias.
Plants of the new Gazania can be compared to plants of the cultivar Mitsuwa Yellow, not patented. In side-by-side comparisons conducted by the Inventor in Ontario, Calif., plants of the new Gazania differed from plants of the cultivar Mitsuwa Yellow in the following characteristics:
-
- 1. Plants of the new Gazania had slightly narrower leaves than plants of the cultivar Mitsuwa Yellow.
- 2. Plants of the new Gazania were more freely flowering than plants of the cultivar Mitsuwa Yellow.
- 3. Plants of the new Gazania had larger inflorescences with more ray florets per inflorescence than plants of the cultivar Mitsuwa Yellow.
- 4. Ray florets of plants of the new Gazania were yellow and orange bi-colored whereas ray florets of plants of the cultivar Mitsuwa Yellow were yellow in color.
The accompanying colored photographs illustrate the overall appearance of the new cultivar, 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 Gazania.
The photograph at the top of the sheet comprises a side perspective view of a typical plant of ‘California Gold’ grown in a container.
The photograph at the bottom of the sheet comprises a close-up view of typical inflorescences and leaves of ‘California Gold’.
The aforementioned photographs and following observations and measurements describe plants grown in Ojai, Calif. during the summer and autumn in an outdoor nursery with day temperatures ranging from 24 to 38° C. and night temperatures ranging from 10 to 18° C. Rooted liners of the new Gazania were planted in 15.25-cm containers with three plants per container and had been growing for about three months when the photographs and description were taken.
