Veronica plant named ‘Verbrig’

Abstract

A new and distinct cultivar of Veronica plant named ‘Verbrig’, characterized by its upright. outwardly spreading and low mounding plant habit; freely basal branching habit; dense and bushy plant form; variegated foliage; freely flowering habit; and violet blue-colored flowers.

Description

Botanical designation: Veronica prostrata.

Cultivar denomination: ‘Verbrig’.

BACKGROUND OF THE INVENTION

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

The new Veronica is a naturally-occurring branch mutation of an unnamed selection of Veronica prostrata, not patented. The new Veronica was discovered and selected by the Inventor in 1996 from within a population of plants of the present selection in a controlled environment in County of Surrey, United Kingdom.

Asexual reproduction of the new cultivar by cuttings since 1996 in County of Surrey, United Kingdom, has shown that the unique features of this new Veronica are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the cultivar Verbrig have 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 following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Verbrig’. These characteristics in combination distinguish ‘Verbrig’ as a new and distinct Veronica cultivar:

• • 1. Upright, outwardly spreading and low mounding plant habit.
  • 2. Freely basal branching habit, dense and bushy plant form.
  • 3. Variegated foliage.
  • 4. Freely flowering habit.
  • 5. Violet blue-colored flowers.

Plants of the new Veronica can be compared to the parent selection. Plants of the new Veronica differ primarily from plants of the parent selection in foliage color as plants of the parent selection do not have variegated foliage.

Plants of the new Veronica can be compared to plants of the Veronica cultivar Blue Sheen, not patented. In side-by-side comparisons conducted in Bressingham, Norfolk, United Kingdom, plants of the new Veronica differed from plants of the cultivar Blue Sheen in the following characteristics:

• • 1. Plants of the new Veronica were more compact than plants of the cultivar Blue Sheen.
  • 2. During the winter, plants of the new Veronica had reddish stems whereas than plants of the cultivar Blue Sheen had green-colored stems.
  • 3. Plants of the new Veronica had longer leaves than plants of the cultivar Blue Sheen.
  • 4. Plants of the new Veronica had variegated foliage whereas plants of the cultivar Blue Sheen had green-colored foliage.
  • 5. Plants of the new Veronica were more freely flowering than plants of the cultivar Blue Sheen.
  • 6. Plants of the new Veronica had larger flowers than plants of the cultivar Blue Sheen.
  • 7. Flowers of plants of the new Veronica were darker in color than flowers of plants of the cultivar Blue Sheen.

Plants of the new Veronica can also be compared to plants of the Veronica cultivar Trehane, not patented. In side-by-side comparisons conducted in Bressingham, Norfolk, United Kingdom, plants of the new Veronica differed from plants of the cultivar Trehane in the following characteristics:

• • 1. Plants of the new Veronica were more compact than plants of the cultivar Trehane.
  • 2. During the winter, plants of the new Veronica had reddish stems whereas than plants of the cultivar Trehane had yellow green-colored stems.
  • 3. Plants of the new Veronica had broader leaves than plants of the cultivar Trehane.
  • 4. Plants of the new Veronica had variegated foliage whereas plants of the cultivar Trehane had yellow green-colored foliage.
  • 5. Plants of the new Veronica were more freely flowering than plants of the cultivar Trehane.
  • 6. Plants of the new Veronica had larger flowers than plants of the cultivar Trehane.
  • 7. Flowers of plants of the new Veronica were darker in color than flowers of plants of the cultivar Trehane.
