plant named ‘DSANTALG’

Abstract

A new and distinct cultivar of Sanvitalia plant named ‘DSANTALG’, characterized by its mounding to semi-trailing plant habit; moderately vigorous growth habit; early and freely flowering habit; inflorescences with golden yellow-colored ray florets and yellow green to bright yellow-colored disc florets; and good garden performance.

Description

Botanical designation: Sanvitalia speciosa.

Cultivar denomination: ‘DSANTALG’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Sanvitalia plant, botanically known as Sanvitalia speciosa, and hereinafter referred to by the name ‘DSANTALG’.

The new Sanvitalia plant is a product of a planned breeding program conducted by the Inventor in Nir-Zvi and Mishmar Hashiva, Israel. The objective of the breeding program is to create new compact mounding Sanvitalia plants that flower early and have numerous attractive inflorescences.

The new Sanvitalia plant originated from an open-pollination in Nir-Zvi, Israel of a proprietary selection of Sanvitalia speciosa identified as code number SN-14-697, not patented, as the female, or seed, parent with an unknown selection of Sanvitalia speciosa as the male, or pollen, parent. The new Sanvitalia plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated open-pollination in a controlled greenhouse environment in Mishmar Hashiva, Israel on Jan. 15, 2017.

Asexual reproduction of the new Sanvitalia plant by vegetative terminal cuttings in a controlled environment in Mishmar Hashiva, Israel since Jan. 15, 2017 has shown that the unique features of this new Sanvitalia plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Sanvitalia have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions 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 ‘DSANTALG’. These characteristics in combination distinguish ‘DSANTALG’ as a new and distinct Sanvitalia plant:

• • 1. Mounding to semi-trailing plant habit.
  • 2. Moderately vigorous growth habit.
  • 3. Early and freely flowering habit.
  • 4. Inflorescences with golden yellow-colored ray florets and yellow green to bright yellow-colored disc florets.
  • 5. Good garden performance.

Plants of the new Sanvitalia differ primarily from plants of the female parent selection in plant habit as plants of the new Sanvitalia are more mounding than plants of the female parent selection. In addition, leaves of plants of the new Sanvitalia are darker green in color than leaves of plants of the female parent selection.

Plants of the new Sanvitalia can be compared to plants of Sanvitalia speciosa ‘Aztek Gold’, not patented. In side-by-side comparisons plants of the new Sanvitalia differ primarily from plants of ‘Aztek Gold’ in the following characteristics:

• • 1. Plants of the new Sanvitalia are more mounding and semi-trailing than plants of ‘Aztek Gold’.
  • 2. Plants of the new Sanvitalia are more freely branching than plants of ‘Aztek Gold’.
  • 3. Plants of the new Sanvitalia are more freely flowering than plants of ‘Aztek Gold’.

Plants of the new Sanvitalia can also be compared to plants of Sanvitalia speciosa ‘Talya Great Yellow’, not patented. In side-by-side comparisons plants of the new Sanvitalia differ primarily from plants of ‘Talya Great Yellow’ in the following characteristics:

• • 1. Plants of the new Sanvitalia are more semi-trailing than plants of ‘Talya Great Yellow’.
  • 2. Leaves of plants of the new Sanvitalia are broader and darker green in color than leaves of plants of ‘Talya Great Yellow’.
  • 3. Plants of the new Sanvitalia have smaller inflorescences than plants of ‘Talya Great Yellow’.
  • 4. Ray florets of plants of the new Sanvitalia are broader than ray florets of plants of ‘Talya Great Yellow’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs illustrate the overall appearance of the new Sanvitalia plant 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 Sanvitalia plant.

The photograph on the first sheet (FIG. 1 of 2) is a side perspective view of a typical flowering plant of ‘DSANTALG’ grown in a container.

The photograph on the second sheet (FIG. 2 of 2) is a close-up view of a typical inflorescences of ‘DSANTALG’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown during the autumn in 13-cm containers in a polyethylene-covered greenhouse and finished in an outdoor nursery in Nir-Zvi, Israel under conditions and practices which approximate those generally used in commercial Sanvitalia production. During the production of the plants, day temperatures ranged from 17° C. to 25° C., night temperatures ranged from 7° C. to 18° C. and light levels averaged 4,500 lux. Plants were pinched one time four days before planting and were eight weeks from planting when the photographs were taken and ten weeks from planting when the description was taken.
