USPP15914P2 - Veronica plant named ‘Amethyst’ - Google Patents

Abstract

A distinct cultivar of Veronica plant named ‘Amethyst’, characterized by its upright and uniform plant habit; vigorous growth habit; strong stems; relatively small leaves; freely flowering habit; and violet-colored flowers.

Description

Botanical classification/cultivar designation: Veronica spicata cultivar Amethyst.

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 cultivar name Amethyst.

The new Veronica is a product of a planned breeding program conducted by the Inventor in El Quinche, Pichincha, Ecuador. The objective of the breeding program is to develop new dark blue-colored cultivars of Veronica with good stem and foliage quality.

The new Veronica plant originated from a cross-pollination of a proprietary selection of Veronica spicata identified as Code 07, not patented, as the female, or seed, parent with an unknown selection of Veronica spicata, not patented, as the male, or pollen, parent. The new Veronica was discovered by the Inventor in August, 1999 in a controlled environment in El Quinche, Pichincha, Ecuador.

Asexual reproduction of the new cultivar by cuttings in a controlled environment in El Quinche, Pichincha, Ecuador since April, 2000, 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 Amethyst have not been observed under all possible environmental and cultural 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 ‘Amethyst’. These characteristics in combination distinguish ‘Amethyst’ as a new and distinct cultivar:

• • 1. Upright and uniform plant habit.
  • 2. Vigorous growth habit.
  • 3. Strong stems.
  • 4. Relatively small leaves.
  • 5. Freely flowering habit.
  • 6. Violet-colored flowers.

Compared to plants of the female parent selection, plants of the new Veronica are more vigorous, have shorter inflorescences, have larger flowers and have darker violet-colored flowers.

Plants of the new Veronica can be compared to plants of the Veronica cultivar Aquamarine, disclosed in a U.S. Plant patent application Ser. No. 10/888,915. In side-by-side comparisons conducted in El Quinche, Pichincha, Ecuador, plants of the new Veronica differed from plants of the cultivar Aquamarine in the following characteristics:

• • 1. Plants of the new Veronica were shorter than plants of the cultivar Amethyst.
  • 2. Plants of the new Veronica had longer inflorescences and larger flowers than plants of the cultivar Amethyst.

Plants of the new Veronica can also be compared to plants of the Veronica cultivar Verona, not patented. In side-by-side comparisons conducted in El Quinche, Pichincha, Ecuador, plants of the new Veronica differed from plants of the cultivar Verona in the following characteristics:

• • 1. Plants of the new Veronica grew faster and flowered earlier than plants of the cultivar Verona.
  • 2. Plants of the new Veronica had shorter inflorescences than plants of the cultivar Verona.
  • 3. Plants of the new Veronica had larger flowers than plants of the cultivar Verona.
  • 4. Plants of the new Veronica had darker violet-colored flowers than plants of the cultivar Verona.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearance of the new Veronica, 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 colors of the new Veronica.

The photograph comprises a side perspective view of a typical flowering stem of ‘Amethyst’.
