plant named ‘Finemangpine’

Abstract

A new and distinct cultivar of Nemesia plant named ‘Finemangpine’, characterized by its upright, outwardly spreading and uniformly mounded growth habit; freely branching and flowering plant habit; large creamy yellow-colored flowers that are fragrant; relatively tolerant to high temperatures; and good garden performance.

Description

Botanical designation: Nemesia hybrida.

Cultivar denomination: ‘FINEMANGPINE’.

BACKGROUND OF THE INVENTION

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

The new Nemesia plant is a product of a planned breeding program conducted by the Inventor in De Lier, The Netherlands. The objective of the breeding program is to create new Nemesia plants with good vigor and attractive flower coloration.

The new Nemesia plant is a naturally-occurring branch mutation of Nemesia hybrida ‘Kirine-34’, disclosed in U.S. Plant Pat. No. 19,361. The new Nemesia plant was discovered and selected by the Inventor on a single flowering plant of ‘Kirine-34’ within a population of plants of ‘Kirine-34’ in a controlled greenhouse environment in De Lier, The Netherlands in April, 2009.

Asexual reproduction of the new Nemesia plant by terminal cuttings in a controlled environment in De Lier, The Netherlands since April, 2009 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 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 ‘Finemangpine’. These characteristics in combination distinguish ‘Finemangpine’ as a new and distinct Nemesia plant:

• • 1. Upright, outwardly spreading and uniformly mounded growth habit.
  • 2. Freely branching and flowering plant habit.
  • 3. Large creamy yellow-colored flowers that are fragrant.
  • 4. Relatively tolerant to high temperatures.
  • 5. Good garden performance.

Plants of the new Nemesia can be compared to plants of the parent, ‘Kirine-34’. Plants of the new Nemesia differ primarily from ‘Kirine-34’ in flower color as plants of the new Nemesia have lighter yellow-colored flowers than plants of ‘Kirine-34’.

Plants of the new Nemesia can also be compared to plants of the Nemesia hybrida ‘Inupyel’, disclosed in U.S. Plant Pat. No. 17,541. In side-by-side comparisons conducted in De Lier, The Netherlands, plants of the new Nemesia differed primarily from plants of ‘Inupyel’ in the following characteristics:

• • 1. Plants of the new Nemesia had shorter peduncles than plants of ‘Inupyel’.
  • 2. Plants of the new Nemesia and ‘Inupyel’ differed slightly in flower color.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearance of the new Nemesia plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Nemesia plant.

The photograph comprises a side perspective view of a typical flowering plant of ‘Finemangpine’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

Plants used for the aforementioned photograph and following description were grown under environmental conditions and cultural practices which closely approximate commercial production conditions during the summer and autumn in 12-cm containers in a glass-covered greenhouse in De Lier, The Netherlands. During the production of the plants, day temperatures ranged from 17° C. to 30° C. and night temperatures ranged from 16° C. to 18° C. Plants were pinched about two weeks after planting and were eight weeks old when the photograph and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, Fifth Edition, except where general terms of ordinary dictionary significance are used.
