Scoparia plant named ‘USSCO401-3’

Abstract

A new and distinct cultivar of Scoparia plant named ‘USSCO401-3’, characterized by its low-mounding and outwardly spreading growth habit; freely branching habit; early and freely flowering habit; small yellow-colored flowers; and good garden performance.

Description

Botanical designation: Scoparia hybrid.

Cultivar denomination: ‘USSCO401-3’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Scoparia, botanically known as Scoparia hybrid and hereinafter referred to by the name ‘USSCO401-3’.

The new Scoparia is a product of a planned breeding program conducted by the Inventor in Hikone, Shiga, Japan. The objective of the breeding program is to create new Scoparia cultivars with uniform plant habit and numerous attractive flowers.

The new Scoparia originated from a cross-pollination made by the Inventor on Apr. 10, 2004 in Hikone, Shiga, Japan of an unnamed selection of Scoparia montevidensis, not patented, as the female, or seed, parent with the Scoparia hybrid cultivar Suntutuki, disclosed in U.S. Plant Pat. No. 16,345, as the male, or pollen, parent. The new Scoparia 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 Bonsall, Calif. on May 26, 2005.

Asexual reproduction of the new Scoparia by terminal cuttings in a controlled environment in Bonsall, Calif. since Jul. 1, 2005 has shown that the unique features of this new Scoparia are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The cultivar USSCO401-3 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 ‘USSCO401-3’. These characteristics in combination distinguish ‘USSCO401-3’ as a new and distinct cultivar of Scoparia:

• • 1. Low-mounding and outwardly spreading growth habit.
  • 2. Freely branching habit.
  • 3. Early and freely flowering habit.
  • 4. Small yellow-colored flowers.
  • 5. Good garden performance.

The new Scoparia can be compared to plants of the female parent selection. 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 vigorous than plants of the female parent selection.
  • 2. Plants of the new Scoparia and the female parent selection differ in leaf shape as plants of the female parent selection have rounded leaves.

Plants of the new Scoparia can be compared to plants of the male parent, the cultivar Suntutuki. Plants of the new Scoparia differ from plants of the cultivar Suntutuki in the following characteristics:

• • 1. Plants of the new Scoparia are more vigorous than plants of the cultivar Suntutuki.
  • 2. Plants of the new Scoparia flower earlier than plants of the cultivar Suntutuki.
  • 3. Leaves of plants of the new Scoparia are not as lacy as leaves of plants of the cultivar Suntutuki.

Plants of the new Scoparia can be compared to plants of the cultivar Melongolly Blue, not patented. In side-by-side comparisons conducted in Bonsall, Calif., plants of the new Scoparia differed from plants of the cultivar Melongolly Blue in the following characteristics:

• • 1. Plants of the new Scoparia were not as upright as plants of the cultivar Melongolly Blue.
  • 2. Plants of the new Scoparia and the cultivar Melongolly Blue differed in flower color as plants of the cultivar Melongolly Blue had blue-colored flowers.

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.

The photograph at the bottom of the sheet comprises a side perspective view of a typical flowering plant of ‘USSCO401-3’ grown in a container.

The photograph at the top of the sheet comprises a close-up of typical flowers and leaves of ‘USSCO401-3’.
