plant named ‘GG Pink’

Abstract

A new and distinct cultivar of Nemesia plant named ‘GG Pink’, characterized by its compact, upright and mounded growth habit; freely branching habit; freely flowering habit; long flowering period; dark pink-colored flowers; and good garden performance.

Description

Botanical designation: Nemesia hybrida.

Cultivar denomination: ‘GG Pink’.

BACKGROUND OF THE INVENTION

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

The new Nemesia plant is a product of a planned breeding program conducted by the Inventor in Hiratuka, Kanagawa, Japan. The objective of the breeding program is to create new compact, mounding and freely-branching Nemesia cultivars with attractive flower coloration.

The new Nemesia plant originated from a cross-pollination made by the Inventor in November, 2005 in Hiratuka, Kanagawa, Japan of a proprietary selection of Nemesia hybrida identified as code number TNP-4, not patented, as the female, or seed, parent with Nemesia hybrida ‘Peach Doll’, not patented, as the male, or pollen, parent. The new Nemesia was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination in a controlled greenhouse environment in Hiratuka, Kanagawa, Japan in April, 2006.

Asexual reproduction of the new Nemesia plant by vegetative cuttings in a controlled environment in Hiratuka, Kanagawa, Japan since May, 2006, has shown that the unique features of this new Nemesia are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Nemesia have 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 ‘GG Pink’. These characteristics in combination distinguish ‘GG Pink’ as a new and distinct cultivar of Nemesia:

• • 1. Compact, upright and mounded growth habit.
  • 2. Freely branching habit.
  • 3. Freely flowering habit.
  • 4. Long flowering period.
  • 5. Dark pink-colored flowers.
  • 6. Good garden performance.

Plants of the new Nemesia can be compared to plants of the female parent selection. Plants of the new Nemesia differ from plants of the female parent selection primarily in flower color as plants of the female parent selection have light pink-colored flowers.

Plants of the new Nemesia can be compared to plants of the male parent, ‘Peach Doll’. Plants of the new Nemesia differ from plants of ‘Peach Doll’ in the following characteristics:

• • 1. Plants of the new Nemesia are more compact and mounding than plants of ‘Peach Doll’.
  • 2. Plants of the new Nemesia are more freely branching than plants of ‘Peach Doll’.

Plants of the new Nemesia can also be compared to plants of ‘Mellow Dessert Peach’, not patented. In side-by-side comparisons conducted by the Inventor in Hiratuka, Kanagawa, Japan, plants of the new Nemesia differed from plants of ‘Mellow Dessert Peach’ in the following characteristics:

• • 1. Plants of the new Nemesia were more compact and mounding than plants of ‘Mellow Dessert Peach’.
  • 2. Plants of the new Nemesia were more freely branching than plants of ‘Mellow Dessert Peach’.
  • 3. Plants of the new Nemesia had smaller leaves than plants of ‘Mellow Dessert Peach’.
  • 4. Plants of the new Nemesia are more freely flowering than plants of ‘Mellow Dessert Peach’.
