Sanvitalia plant named ‘Starbini’

Abstract

A new and distinct cultivar of Sanvitalia plant named ‘Starbini’, characterized by its compact, outwardly spreading and low-mounded plant habit; freely branching habit and short internodes, dense and bushy plants; dark green-colored foliage; long and freely flowering habit with flowers held just above and beyond the foliage; and single daisy inflorescence form with yellow-colored ray florets.

Description

Botanical designation: Sanvitalia speciosa.

Cultivar denomination: ‘Starbini’.

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 cultivar name ‘Starbini’.

The new Sanvitalia is a product of a planned breeding program conducted by the Inventor in Deitingen, Switzerland. The objective of the program is to create and develop new compact Sanvitalia cultivars with numerous inflorescences and attractive ray floret coloration.

The new Sanvitalia originated from a cross-pollination by the Inventor of two unnamed Sanvitalia speciosa seedling selections, not patented. The new Sanvitalia was discovered and selected by the Inventor as a plant within the progeny of the stated cross-pollination in a controlled environment in Deitingen, Switzerland in 2001. The selection of the new Sanvitalia was based on its compact and freely flowering habit.

Asexual reproduction of the new Sanvitalia by terminal cuttings in a controlled environment in Deitingen, Switzerland since 2001, has shown that the unique features of this new Sanvitalia are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The new Sanvitalia 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 ‘Starbini’ and distinguish the new Sanvitalia as a new and distinct cultivar:

• • 1. Compact, outwardly spreading and low-mounded plant habit.
  • 2. Freely branching habit and short internodes, dense and bushy plants.
  • 3. Dark green-colored foliage.
  • 4. Long and freely flowering habit with flowers held just above and beyond the foliage.
  • 5. Single daisy inflorescence form with yellow-colored ray florets.

Plants of the new Sanvitalia differ from plants of the parent selections primarily in plant growth habit as plants of the new Sanvitalia are more uniform and more compact than plants of the parent selections.

Plants of the new Sanvitalia can be compared to plants of the cultivar Dittsun, disclosed in U.S. Plant Pat. No. 14,140. In side-by-side comparisons conducted in Deitingen, Switzerland, plants of the new Sanvitalia differed from plants of the cultivar Dittsun in the following characteristics:

• • 1. Plants of the new Sanvitalia were more outwardly spreading than and not as upright as plants of the cultivar Dittsun.
  • 2. Plants of the new Sanvitalia and the cultivar Dittsun differed in leaf coloration.

The photograph at the top of the sheet comprises a close-up view of typical leaves and inflorescences of ‘Starbini’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs, following observations and averaged measurements describe plants grown in Bonsall, Calif., in a polyethylene-covered greenhouse during the fall with day temperatures ranging from 13° C. to 35° C. and night temperatures ranging from 4° C. to 13° C. Plants were grown for about 14 weeks in 15-cm containers.
