Abstract
A new and distinct cultivar of Chrysocephalum plant named ‘Silsun’, characterized by its compact, low spreading and mounding plant habit; silvery pubescent leaves and stems; freely flowering habit; large inflorescences positioned above the foliage; bright yellow-colored inflorescences; and good garden performance.
Description
Botanical designation: Chrysocephalum apiculatum.
Cultivar denomination: ‘Silsun’.
The present invention relates to a new and distinct cultivar of Chrysocephalum, botanically known as Chrysocephalum apiculatum and hereinafter referred to by the name ‘Silsun’.
The new Chrysocephalum originated from an open-pollination in Cranbourne, Victoria, Australia, of an unnamed selection of Chrysocephalum apiculatum, not patented, as the female, or seed, parent with an unknown selection of Chrysocephalum apiculatum as the male, or pollen, parent. The new Chrysocephalum was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated open-pollination in a controlled environment in Cranbourne, Victoria, Australia in April, 2004.
Asexual reproduction of the new Chrysocephalum by vegetative cuttings in a controlled environment in Cranbourne, Victoria, Australia since August, 2004 has shown that the unique features of this new Chrysocephalum are stable and reproduced true to type in successive generations.
The cultivar Silsun 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 ‘Silsun’. These characteristics in combination distinguish ‘Silsun’ as a new and distinct cultivar of Chrysocephalum:
-
- 1. Compact, low spreading and mounding plant habit.
- 2. Silvery pubescent leaves and stems.
- 3. Freely flowering habit.
- 4. Large inflorescences positioned above the foliage.
- 5. Bright yellow-colored inflorescences.
- 6. Good garden performance.
Plants of the new Chrysosephalum differ from plants of the female parent selection in the following characteristics:
-
- 1. Plants of the new Chrysocephalum are more compact than plants of the female parent selection.
- 2. Plants of the new Chrysocephalum have larger inflorescences than plants of the female parent selection.
Plants of the new Chrysocephalum can be compared to plants of the Chrysocephalum cultivar Golden Buttons, not patented. In side-by-side comparisons conducted in Cranbourne, Victoria, Australia, plants of the new Chrysocephalum differed from plants of the cultivar Golden Buttons in the following characteristics:
-
- 1. Plants of the new Chrysocephalum were more compact, spreading and mounding than plants of the cultivar Golden Buttons.
- 2. Stems of plants of the new Chrysocephalum were thicker, more spreading and pubescent than stems of plants of the cultivar Golden Buttons.
- 3. Plants of the new Chrysocephalum were more freely branching than plants of the cultivar Golden Buttons.
- 4. Plants of the new Chrysocephalum were more freely flowering than plants of the cultivar Golden Buttons.
- 5. Plants of the new Chrysocephalum had larger inflorescences than plants of the cultivar Golden Buttons.
- 6. Inflorescences of plants of the new Chrysocephalum were paler yellow in color than inflorescences of the cultivar Golden Buttons.
- 7. Plants of the new Chrysocephalum had longer and thicker peduncles than plants of the cultivar Golden Buttons.
The accompanying colored photographs illustrate the overall appearance of the new Chrysocephalum, 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 Chrysocephalum.
The photograph on the first sheet comprises a side perspective view of typical flowering plants of ‘Silsun’ grown in a container.
The photograph on the second sheet is a close-up view of typical inflorescences of ‘Silsun’.
The aforementioned photographs and following observations, measurements and values describe plants grown in 20-cm containers in Cranbourne, Victoria, Australia, under commercial practice during the spring and summer in a polyethylene-covered greenhouse with day temperatures ranging from 10° C. to 40° C., night temperatures ranging from 4° C. to 28° C. and light levels ranging from 5,000 lux to 9,000 lux. Plants were pinched at planting and then a second time five weeks later. Plants had been growing for about six months when the photographs and the description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
