Geranium plant named ‘Dueazulia’

Abstract

A new and distinct cultivar of Zonal Geranium plant named ‘Dueazulia’, characterized by its upright, somewhat outwardly spreading and rounded plant habit; freely branching habit; dark green-colored foliage; freely and early flowering habit; and red purple-colored semi-double flowers.

Description

Botanical designation: Pelargonium×hortorum.

Variety denomination: ‘Dueazulia’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Zonal Geranium plant, botanically known as Pelargonium×hortorum, and hereinafter referred to by the name ‘Dueazulia’.

The new Zonal Geranium is a product of a planned breeding program conducted by the Inventor in Rheinberg, Germany. The objective of the breeding program was to develop new freely and early flowering Zonal Geraniums with attractive flower and foliage colors.

The new Zonal Geranium originated from a cross-pollination made by the Inventor in May, 1998, of two unnamed selections of Pelargonium×hortorum, not patented. The cultivar Dueazulia was discovered and selected by the Inventor as a single flowering plant within the progeny from this stated cross-pollination in a controlled environment in Rheinberg, Germany in April, 2001.

Asexual reproduction of the new cultivar by terminal vegetative cuttings at Rheinberg, Germany since July, 2001, has shown that the unique features of this new Zonal Geranium are stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Dueazulia’. These characteristics in combination distinguish ‘Dueazulia’ as a new cultivar and distinguish it from other known Zonal Geranium cultivars:

• • 1. Upright, somewhat outwardly spreading and rounded plant habit.
  • 2. Freely branching habit.
  • 3. Dark green-colored foliage.
  • 4. Freely and early flowering habit.
  • 5. Red purple-colored semi-double flowers.

Plants of the new Zonal Geranium differ from plants of the parent selections in flower color.

The new Zonal Geranium can be compared to plants of the cultivar Arcona 2000, not patented. In side-by-side comparisons conducted in Rheinberg, Germany, plants of the new Zonal Geranium differed from plants of the cultivar Arcona 2000 in the following characteristics:

• • 1. Plants of the new Zonal Geranium were more densely foliated than plants of the cultivar Arcona 2000.
  • 2. Flowers of plants of the new Zonal Geranium were more red purple in color than flowers of plants of cultivar Arcona 2000.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearance of the new cultivar, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Flower and foliage 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 Zonal Geranium. The photograph comprises a side perspective view of a typical flowering plant of ‘Dueazulia’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

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

The aforementioned photograph, following observations and measurements describe plants grown in Rheinberg, Germany during the summer under commercial practice in a glass-covered greenhouse with day and night temperatures about 18° C. and light levels about 4,500 foot-candles. Plants were grown in 10.5-cm containers. Plants were pinched once about three weeks after planting. Plants were about eight weeks from unrooted cuttings when the photograph and the detailed botanical description were taken.
