Abstract

A new and distinct cultivar of Veronica plant named ‘Charlotte’, characterized by its upright plant habit; relatively small variegated leaves; dense inflorescences with numerous white-colored flowers; and good garden performance.

Description

Botanical designation: Veronica longifolia.

Cultivar denomination: ‘CHARLOTTE’.

BACKGROUND OF THE INVENTION

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

The new Veronica plant is a naturally-occurring branch mutation of Veronica longifolia ‘Melanie White’, not patented. The new Veronica plant was discovered and selected by the Inventor on a single flowering plant from within a population of plants of ‘Melanie White’ in a controlled outdoor nursery environment in Roelofarendsveen, The Netherlands during the summer of 2007.

Asexual reproduction of the new Veronica plant by softwood cuttings in a controlled environment in Roelofarendsveen, The Netherlands since the summer of 2007, 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 ‘Charlotte’. These characteristics in combination distinguish ‘Charlotte’ as a new and distinct Veronica plant:

- 1. Upright plant habit.
- 2. Relatively small variegated leaves.
- 3. Dense inflorescences with numerous white-colored flowers.
- 4. Good garden performance.

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

- 1. Plants of the new Veronica have smaller leaves than plants of ‘Melanie White’.
- 2. Plants of the new Veronica have variegated leaves whereas plants of ‘Melanie White’ have solid green-colored (non-variegated) leaves.

Plants of the new Veronica can be compared to plants of Veronica longifolia ‘Schneeriesin’, not patented. In side-by-side comparisons conducted in Roelofarendsveen, The Netherlands, plants of the new Veronica differed primarily from plants of ‘Schneeriesin’ in leaf color as plants of ‘Schneeriesin’ had solid green-colored (non-variegated) leaves.

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 ‘Charlotte’ grown in a container.

The photograph on the second sheet is a close-up view of a typical flowering plant of ‘Charlotte’.

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

DETAILED BOTANICAL DESCRIPTION

Plants used for the aforementioned photographs and following description were grown during the summer in an outdoor nursery in Boskoop, The Netherlands and under environmental conditions and cultural practices which closely approximate commercial Veronica production. During the production of the plants, day temperatures ranged from 14° C. to 28° C. and night temperatures ranged from 8° C. to 16° C. Plants were one year 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.
