Abstract

A new and distinct cultivar of Veronica plant named ‘Verswhite’, characterized by its compact and broadly upright plant habit; freely branching habit; dense and bushy appearance; strong flowering stems; freely flowering habit; long flowering period; dense inflorescences with numerous white-colored flowers; and good garden performance.

Description

Botanical designation: Veronica spicata.

Cultivar denomination: ‘VERSWHITE’.

BACKGROUND OF THE INVENTION

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

The new Veronica plant is a product of a planned breeding program conducted by the Inventor in Haarlem, The Netherlands. The objective of the breeding program was to create new compact and freely-flowering Veronica plants with large inflorescences with attractive flowers.

The new Veronica plant originated from a cross-pollination made by the Inventor in 2008 in Haarlem, The Netherlands of two unnamed seedling selections of Veronica spicata, not patented. The new Veronica plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in Haarlem, The Netherlands in 2010.

Asexual reproduction of the new Veronica plant by cuttings in a controlled environment in Haarlem, The Netherlands since 2010 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 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 ‘Verswhite’. These characteristics in combination distinguish ‘Verswhite’ as a new and distinct Veronica plant:

- 1. Compact and broadly upright plant habit.
- 2. Freely branching habit; dense and bushy appearance.
- 3. Strong flowering stems.
- 4. Freely flowering habit.
- 5. Long flowering period.
- 6. Dense inflorescences with numerous white-colored flowers.
- 7. Good garden performance.

Plants of the new Veronica differ primarily from plants of the parent selections in the following characteristics:

- 1. Plants of the new Veronica are more compact than plants of the parent selections.
- 2. Plants of the new Veronica have stronger flowering stems than plants of the parent selections.
- 3. Plants of the new Veronica are more freely flowering than plants of the parent selections.

Plants of the new Veronica can be compared to plants of Veronica spicata ‘Icicle’, not patented. In side-by-side comparisons, plants of the new Veronica differed primarily from plants of ‘Icicle’ in the following characteristics:

- 1. Plants of the new Veronica were more compact than plants of ‘Icicle’.
- 2. Plants of the new Veronica had stronger flowering stems than plants of ‘Icicle’.
- 3. Plants of the new Veronica were more freely flowering than plants of ‘Icicle’.
- 4. Plants of the new Veronica flowered for a longer period of time than plants of ‘Icicle’.
- 5. Plants of the new Veronica and ‘Icicle’ differ in flower color as plants of ‘Icicle’ had red-colored flowers.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the 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 ‘Verswhite’ grown in an outdoor nursery.

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

DETAILED BOTANICAL DESCRIPTION

Plants used for the aforementioned photographs and following description were grown during the late summer/early autumn in an outdoor nursery in Haarlem, The Netherlands and under cultural practices typical of commercial production. During the production of the plants, day temperatures ranged from 16° C. to 32° C. and night temperatures ranged from 6° C. to 18° C. Plants were two years old when the photographs and the 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.
