plant named ‘GOM070101’

Abstract

A new and distinct cultivar of Gomphrena plant named ‘GOM070101’, characterized by its mounding plant habit; vigorous growth habit; freely branching habit; large pubescent leaves; and large long-lasting inflorescences with numerous red purple-colored flowers.

Description

Botanical designation: Gomphrena hybrida.

Cultivar denomination: ‘GOM070101’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Gomphrena plant, botanically known as Gomphrena hybrida and hereinafter referred to by the name ‘GOM070101’.

The new Gomphrena plant is a product of a planned breeding program conducted by the Inventors in Higashiomi, Shiga, Japan. The objective of the breeding program is to create new mounding Gomphrena plants with large long-lasting inflorescences.

The new Gomphrena plant was discovered and selected by the Inventors as a single flowering plant from within the progeny of a cross-pollination of an unidentified selection of Gomphrena macrocephala, not patented, as the female, or seed, parent with an unidentified selection of Gomphrena hybrida as the male, or pollen, parent, in a controlled environment in Higashiomi, Shiga, Japan on Aug. 12, 2006. The new Gomphrena plant was discovered and selected by the Inventors as a single flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in Higashiomi, Shiga, Japan on Jul. 10, 2007.

Asexual reproduction of the new Gomphrena plant by terminal cuttings in a controlled environment in Higashiomi, Shiga, Japan since Oct. 5, 2007 has shown that the unique features of this new Gomphrena plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Gomphrena have not been observed under all possible 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 ‘GOM070101’. These characteristics in combination distinguish ‘GOM070101’ as a new and distinct Gomphrena plant:

• • 1. Mounding plant habit.
  • 2. Vigorous growth habit.
  • 3. Freely branching habit.
  • 4. Large pubescent leaves.
  • 5. Large long-lasting inflorescences with numerous red purple-colored flowers.

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

• • 1. Plants of the new Gomphrena are more freely branching than plants of the female parent selection.
  • 2. Plants of the new Gomphrena have smaller inflorescences than plants of the female parent selection.

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

• • 1. Plants of the new Gomphrena are more mounding than and not as upright as plants of the male parent selection.
  • 2. Plants of the new Gomphrena have larger inflorescences than plants of the male parent selection.

Plants of the new Gomphrena can be compared to plants of Gomphrena leontopodioides ‘Balboa’, disclosed in U.S. Plant Pat. No. 22,263. In side-by-side comparisons conducted in Higashiomi, Shiga, Japan, plants of the new Gomphrena differed primarily from plants of ‘Balboa’ in the following characteristics:

• • 1. Plants of the new Gomphrena had larger leaves than plants of ‘Balboa’.
  • 2. Plants of the new Gomphrena had larger inflorescences than plants of ‘Balboa’.
  • 3. Plants of the new Gomphrena and ‘Balboa’ differed in flower color as plants of ‘Balboa’ had purple-colored flowers.

DETAILED BOTANICAL DESCRIPTION

Plants used for the aforementioned photographs and following description were grown under conditions which closely approximate commercial production conditions during the summer in one-gallon containers in a polyethylene-covered greenhouse in Bonsall, Calif.
