plant named ‘Innemblora’

Abstract

A new and distinct cultivar of Nemesia plant named ‘Innemblora’, characterized by its upright to somewhat outwardly spreading and mounding plant habit; vigorous growth habit; freely branching habit; freely flowering habit; long flowering period; dark orange-colored flowers that are sterile; and good summer garden performance.

Description

Botanical designation: Nemesia strumosa×Nemesia fruticans.

Cultivar denomination: ‘INNEMBLORA’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Nemesia plant, botanically known as Nemesia strumosa×Nemesia fruticans and hereinafter referred to by the name ‘Innemblora’.

The new Nemesia plant is a product of a planned breeding program conducted by the Inventor in Heidesheim and Gensingen, Germany. The objective of the breeding program is to create new semi-upright and freely branching Nemesia plants with good summer garden performance.

The new Nemesia plant originated from a cross-pollination made by the Inventor in August, 2011 in Heidesheim, Germany of a proprietary selection of Nemesia strumosa identified as code number N 05 82-1, not patented, as the female, or seed, parent with a proprietary selection of Nemesia fruticans identified as code number N 04 46-48, not patented, as the male, or pollen, parent. The new Nemesia plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination in a controlled environment in Heidesheim, Germany in April, 2012.

Asexual reproduction of the new Nemesia plant by terminal vegetative cuttings in a controlled environment in Gensingen, Germany since September, 2012, has shown that the unique features of this new Nemesia plant 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 combinations of 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 ‘Innemblora’. These characteristics in combination distinguish ‘Innemblora’ as a new and distinct Nemesia plant:

• • 1. Upright to somewhat outwardly spreading and mounding plant habit.
  • 2. Vigorous growth habit.
  • 3. Freely branching habit.
  • 4. Freely flowering habit.
  • 5. Long flowering period.
  • 6. Dark orange-colored flowers that are sterile.
  • 7. Good summer garden performance.

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

• • 1. Plants of the new Nemesia and the female parent selection differ in flower color as plants of the female parent selection have white-colored flowers.
  • 2. Flowers of plants of the new Nemesia are sterile whereas flowers of plants of the female parent selection are fertile.

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

• • 1. Plants of the new Nemesia are more upright than and not as trailing as plants of the male parent selection.
  • 2. Flowers of plants of the new Nemesia are sterile whereas flowers of plants of the male parent selection are fertile.

Plants of the new Nemesia can be compared to plants of Nemesia hybrida ‘Intrairedtwo’, disclosed in U.S. Plant Pat. No. 23,061. In side-by-side comparisons conducted in Gensingen, Germany, plants of the new Nemesia differed from plants of ‘Intrairedtwo’ in the following characteristics:

• • 1. Plants of the new Nemesia were more compact than plants of ‘Intrairedtwo’.
  • 2. Plants of the new Nemesia were more freely branching and denser than plants of ‘Intrairedtwo’.
  • 3. Plants of the new Nemesia and ‘Intrairedtwo’ differed in flower color as plants of ‘Intrairedtwo’ have dark red-colored flowers.

Plants of the new Nemesia can be compared to plants of Nemesia hybrida ‘Intraigoldtwo’, disclosed in U.S. Plant Pat. No. 23,062. In side-by-side comparisons conducted in Gensingen, Germany, plants of the new Nemesia differed from plants of ‘Intraigoldtwo’ in the following characteristics:

• • 1. Plants of the new Nemesia were more compact than plants of ‘Intraigoldtwo’.
  • 2. Plants of the new Nemesia and ‘Intraigoldtwo’ differed in flower color as plants of ‘Intraigoldtwo’ have golden yellow-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 11.5-cm containers in an outdoor nursery in Bonsall, Calif. During the production of the plants, day temperatures averaged 24° C., night temperatures averaged 10° C. and light levels ranged from 7,000 to 10,000 foot-candles. Plants were pinched two times and were nine weeks old when the photographs and description were taken.
