Description

Botanical designation: Veronica virginicum.

Cultivar denomination: ‘CHALLENGER’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct Veronica plant, botanically known as Veronica virginicum and hereinafter referred to by the cultivar name ‘Challenger’.

The new Veronica plant originated from an open-pollination in July, 2011 in Hummelo, The Netherlands, of Veronica virginicum ‘Roseum’, not patented, as the female, or seed, parent with an unknown selection of Veronica virginicum as the male, or pollen, parent. The new Veronica 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 Hummelo, The Netherlands in July, 2013.

Asexual reproduction of the new Veronica plant by vegetative softwood cuttings in Hummelo, The Netherlands, since the spring of 2014, has shown that the unique features of this new Veronica plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Veronica have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype of the new Veronica plant 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 ‘Challenger’. These characteristics in combination distinguish ‘Challenger’ as a new and distinct Veronica plant:

    • 1. Upright and relatively compact plant habit.
    • 2. Moderately freely branching habit.
    • 3. Freely flowering habit.
    • 4. Light purple to white-colored flowers arranged on long racemes.
    • 5. Good garden performance.

Plants of the new Veronica differ primarily from plants of the female parent, ‘Roseum’, in the following characteristics:

    • 1. Plants of the new Veronica are shorter and more compact than plants of ‘Roseum’.
    • 2. Plants of the new Veronica have stronger stems than plants of ‘Roseum’.

Plants of the new Veronica can be compared to plants of Veronica spicata ‘Erica’, not patented. In side-by-side comparisons conducted by the Inventor in Hummelo, The Netherlands, plants of the new Veronica differed from plants of ‘Erica’ in the following characteristics:

    • 1. Plants of the new Veronica were shorter and more compact than plants of ‘Erica’.
    • 2. Plants of the new Veronica were more freely branching than plants of ‘Erica’.
    • 3. Plants of the new Veronica and ‘Erica’ differed in stem color as plants of ‘Erica’ had darker-colored stems.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Veronica 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 actual colors of the new Veronica plant.

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

The photograph on the second sheet is a close-up view of a typical leaf of ‘Challenger’.

The photograph on the third sheet is a close-up view of a typical inflorescence of ‘Challenger’.

 DETAILED BOTANICAL DESCRIPTION

Plants used for the aforementioned photographs and following description were grown during the late summer in an outdoor nursery in Lisserbroek, The Netherlands and under cultural practices typical of Veronica production. During the production of the plants, day temperatures ranged from 15° C. to 25° C. and night temperatures ranged from 8° C. to averaged 18° C. Plants were four months 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.
