plant named ‘Victoria Xenian’

Abstract

A new and distinct cultivar of Aster plant named ‘Victoria Xenian’, characterized by its compact, uniform, upright and mounded plant habit; freely branching growth habit; uniform and freely flowering habit; and decorative-type inflorescences with light red purple-colored ray florets.

Description

Botanical designation: Aster novi-belgii.

Cultivar denomination: ‘VICTORIA XENIAN’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Aster plant, botanically known as Aster novi-belgii and hereinafter referred to by the name ‘Victoria Xenian’.

The objective of the breeding program is to create new compact and fast-growing Aster plants with uniform and rounded plant growth habit, freely branching habit and attractive floret colors.

The new Aster originated from an open-pollination in March, 2008 in Aarslev, Denmark of Aster novi-belgii ‘Victoria Mathilde’, disclosed in U.S. Plant Pat. No. 19,930, as the female, or seed, parent with an unknown Aster novi-belgii seedling selection, as the male, or pollen, parent. The new Aster plant was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated open-pollination in a controlled environment in Aarslev, Denmark in April, 2009.

Asexual reproduction of the new Aster plant by vegetative tip cuttings was first conducted in Aarslev, Denmark in September, 2009. Asexual reproduction by cuttings has shown that the unique features of this new Aster plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Aster 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, daylength 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 ‘Victoria Xenian’. These characteristics in combination distinguish ‘Victoria Xenian’ as a new and distinct Aster plant:

• • 1. Compact, uniform, upright and mounded plant habit.
  • 2. Freely branching growth habit.
  • 3. Uniform and freely flowering habit.
  • 4. Decorative-type inflorescences with light red purple-colored ray florets.

Plants of the new Aster differ from plants of the female parent, ‘Victoria Mathilde’, in the following characteristics:

• • 1. Leaves of plants of the new Aster are broader than leaves of plants of ‘Victoria Mathilde’.
  • 2. Plants of the new Aster flower about eight to ten days earlier than plants of ‘Victoria Mathilde’.
  • 3. Plants of the new Aster have larger inflorescences than plants of ‘Victoria Mathilde’.
  • 4. Ray florets of plants of the new Aster flower are lighter in color than ray florets of plants of ‘Victoria Mathilde’.

Plants of the new Aster can be compared to plants of Aster novi-belgii ‘Victoria Pink Fanny’, not patented. In side-by-side comparisons conducted in Aarslev, Denmark, plants of the new Aster differed from plants of ‘Victoria Pink Fanny’ in the following characteristics:

• • 1. Plants of the new Aster were more upright than plants of ‘Victoria Pink Fanny’.
  • 2. Leaves of plants of the new Aster were broader than leaves of plants of ‘Victoria Pink Fanny’.
  • 3. Plants of the new Aster flowered about three to four days earlier than plants of ‘Victoria Pink Fanny’.
  • 4. Ray florets of plants of the new Aster were lighter in color than ray florets of plants of ‘Victoria Pink Fanny’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

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

The photograph on the first sheet comprises a side perspective view of a typical flowering plant of ‘Victoria Xenian’ grown in a container.

The photograph on the second sheet comprises close-up views of the upper (top of the photograph) and lower surfaces (bottom of the photograph) of typical inflorescences and leaves of ‘Victoria Xenian’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown during the late summer in 10.5-cm containers in a glass-covered greenhouse in Marslev, Denmark under environmental conditions and cultural practices which approximate those generally used in commercial container Aster production. During the production of the plants, day temperatures ranged from 19° C. to 20° C. and night temperatures ranged from 18° C. to 19° C. Plants were pinched one time and were twelve weeks old when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2007 Edition, except where general terms of ordinary dictionary significance are used.
