USPP22870P2 - Scoparia plant named ‘Suntutulaki’ - Google Patents

Abstract

A new and distinct cultivar of Scoparia plant named ‘Suntutulaki’, characterized by its upright, outwardly spreading and mounding plant habit; vigorous growth habit; freely branching habit; numerous yellow-colored flowers; long flowering period; and good garden performance.

Description

Botanical designation: Scoparia sp.

Cultivar Denomination: ‘SUNTUTULAKI’.

BACKGROUND OF THE INVENTION

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

The new Scoparia plant is a product of a planned breeding program conducted by the Inventor in Higashiomi, Shiga, Japan. The objective of the breeding program was to create new freely and long flowering Scoparia plants with uniquely-colored flowers.

The new Scoparia plant originated from a cross-pollination made by the Inventor in July, 2006, in Higashiomi, Shiga, Japan, of a proprietary selection of Scoparia sp. identified as code number SC99-1, not patented, as the female, or seed, parent with a proprietary selection of Scoparia sp. identified as code number SC86-1, not patented, as the male, or pollen, parent. The new Scoparia plant was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination in a controlled environment in Higashiomi, Shiga, Japan in June, 2007.

Asexual reproduction of the new Scoparia plant by vegetative cuttings in a controlled environment in Higashiomi, Shiga, Japan since July, 2007, has shown that the unique features of this new Scoparia plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Scoparia have 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 traits have been repeatedly observed and are determined to be the unique characteristics of ‘Suntutulaki’. These characteristics in combination distinguish ‘Suntutulaki’ as a new and distinct cultivar of Scoparia plant:

• • 1. Upright, outwardly spreading and mounding plant habit.
  • 2. Vigorous growth habit.
  • 3. Freely branching habit.
  • 4. Numerous yellow-colored flowers.
  • 5. Long flowering period.
  • 6. Good garden performance.

Plants of the new Scoparia differ from plants of the female parent selection in the following characteristics:

• • 1. Plants of the new Scoparia are more upright than and not as spreading as plants of the female parent selection.
  • 2. Plants of the new Scoparia have larger flowers than plants of the female parent selection.

Plants of the new Scoparia differ from plants of the male parent selection in the following characteristics:

• • 1. Plants of the new Scoparia are not as compact as plants of the male parent selection.
  • 2. Plants of the new Scoparia have larger flowers than plants of the male parent selection.

Plants of the new Scoparia can be compared to plants of Scoparia sp. ‘Suntutuki’, disclosed in U.S. Plant Pat. No. 16,345. In side-by-side comparisons conducted in Higashiomi, Shiga, Japan, plants of the new Scoparia and ‘Suntutuki’ differed in the following characteristics:

• • 1. Plants of the new Scoparia were taller and broader than plants of ‘Suntutuki’.
  • 2. Plants of the new Scoparia had longer internodes than plants of ‘Suntutuki’.
  • 3. Plants of the new Scoparia had broader petals than plants of ‘Suntutuki’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Scoparia 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 Scoparia plant.

The photograph at the top of the sheet comprises a side perspective view of a typical flowering plant of ‘Suntutulaki’ grown in a container.

The photograph at the bottom of the sheet is a close-up view of a typical flowering plant of ‘Suntutulaki’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown during the early summer in 15-cm containers in an outdoor nursery in Higashiomi, Shiga, Japan and under commercial practice. During the production of the plants, day temperatures averaged 23° C. and night temperatures averaged 13° C. Plants were four months old when the photographs and description were taken.
