Nemesia plant named ‘N006-9BLAU’

Abstract

A new and distinct cultivar of Nemesia plant named ‘N006-9BLAU’, characterized by its upright plant habit; freely branching habit; early flowering habit; and numerous purple-colored flowers that are fragrant.

Description

Botanical designation: Nemesia hybrid.

Variety denomination: ‘N006-9BLAU’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Nemesia plant, botanically known as Nemesia hybrid and referred to by the name ‘N006-9BLAU’.

The new Nemesia is a product of a planned breeding program conducted by the Inventors in Gensingen, Germany. The objective of the program is to create new compact and early-flowering Nemesia cultivars with numerous flowers, unique flower colors and fragrance.

The new Nemesia originated from a cross-pollination made by the Inventors of a proprietary Nemesia hybrid selection identified as code N98Sä3tetra2, not patented, as the female, or seed, parent with the Nemesia hybrid cultivar Hubbird, disclosed in U.S. Plant Pat. No. 12,014, as the male, or pollen, parent during the summer of 1999. The cultivar N006-9BLAU was discovered and selected by the Inventors as a flowering plant within the progeny of the stated cross-pollination in a controlled environment in Gensingen, Germany during the summer of 1999.

Asexual reproduction of the new Nemesia by terminal cuttings in a controlled environment in Gensingen, Germany since 1999, has shown that the unique features of this new Nemesia are stable and are reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The new Nemesia has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, daylength and light intensity, without, however, any variance in genotype.

The following characteristics have been repeatedly observed and are determined to be basic characteristics of ‘N006-9BLAU’ and distinguish ‘N006-9BLAU’ as a new and distinct cultivar:

• • 1. Upright plant habit.
  • 2. Freely branching habit.
  • 3. Early flowering habit.
  • 4. Numerous purple-colored flowers that are fragrant.

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

• • 1. Plants of the new Nemesia flower earlier than plants of the female parent selection.
  • 2. Plants of the new Nemesia have larger flowers than plants of the female parent selection.
  • 3. Plants of the new Nemesia are more freely flowering than plants of the female parent selection.

Plants of the new Nemesia differ primarily from plants of the male parent, the cultivar Hubbird, in the following characteristics:

• • 1. Flower color of plants of the new Nemesia is more intense than flower color of plants of the cultivar Hubbird.
  • 2. Flowers of plants of the new Nemesia are more fragrant than flowers of plants of the cultivar Hubbird.

Plants of the new Nemesia can be compared to plants of the cultivar Melanie, not patented. In side-by-side comparisons conducted in Gensingen, Germany, plants of the new Nemesia differed from plants of the cultivar Melanie in the following characteristics:

• • 1. Plants of the new Nemesia were more vigorous than plants of the cultivar Melanie.
  • 2. Plants of the new Nemesia had larger flowers than plants of the cultivar Melanie.
  • 3. Flower color of plants of the new Nemesia was more intense than flower color of plants of the cultivar Melanie.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and averaged measurements describe plants grown in Bonsall, Calif., in an outdoor nursery during the spring with day temperatures ranging from 18 to 35° C. and night temperatures ranging from 7 to 18° C. After rooting, plants were grown for four weeks in 15-cm containers with three plants per container.
