Veronica plant named ‘Verobiblue’

Abstract

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

Description

Botanical designation: Veronica peduncularis.

Cultivar denomination: ‘Verobiblue’.

BACKGROUND OF THE INVENTION

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

The new Veronica is a naturally-occurring whole plant mutation of the Veronica peduncularis cultivar Georgia Blue, not patented. The new Veronica was discovered and selected by the Inventor in 2002 from within a population of plants of the cultivar Georgia Blue in a controlled environment in Gensingen, Germany.

Asexual reproduction of the new cultivar by cuttings since the Spring of 2002 in Gensingen, Germany, 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 ‘Verobiblue’ 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 ‘Verobiblue’. These characteristics in combination distinguish ‘Verobiblue’ as a new and distinct Veronica cultivar:

• • 1. Upright, uniform, outwardly spreading and low-mounding plant habit.
  • 2. Freely basal branching habit, dense and bushy plant form.
  • 3. Early, freely and long flowering habit.
  • 4. Bright violet blue-colored flowers.

Plants of the new Veronica can be compared to the parent, the cultivar Georgia Blue. Plants of the new Veronica differ from plants of the cultivar Georgia Blue in the following characteristics:

• • 1. Plants of the new Veronica flower earlier than plants of the cultivar Georgia Blue.
  • 2. Plants of the new Veronica have larger flowers than plants of the cultivar Georgia Blue.
  • 3. Plants of the new Veronica have darker blue-colored flowers than plants of the cultivar Georgia Blue.

Plants of the new Veronica can also be compared to plants of the Veronica peduncularis cultivar Alba, not patented. Plants of the new Veronica differ from plants of the cultivar Alba in the following characteristics:

• • 1. Plants of the new Veronica flower earlier than plants of the cultivar Alba.
  • 2. Plants of the new Veronica have larger flowers than plants of the cultivar Alba.
  • 3. Plants of the new Veronica and the cultivar Alba differ in flower color as plants of the cultivar Alba have white-colored flowers.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new cultivar, 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.

The photograph on the first sheet comprises a side perspective view of a typical plant of ‘Verobiblue’ grown in an outdoor nursery.

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

DETAILED BOTANICAL DESCRIPTION

Plants shown in the aforementioned photographs and used in the following description were grown under conditions which closely approximate commercial production conditions during the summer in an outdoor nursery in Bonsall, Calif. During the production of the plants, day temperatures ranged from 15° C. to 28° C. and night temperatures ranged from 5° C. to 15° C. Plants were about two months old when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
