Abstract: A new and distinct cultivar of Veronica plant named `Amethyst Plume`, particularly distinguished by lilac-colored flowers in a unique plume-shaped inflorescence, healthy foliage, good mildew and rust resistance, and a well-branched, compact growth habit, is disclosed.
Claim: What is claimed is:

1. A new and distinct cultivar of Veronica plant named `Amethyst Plume`, substantially as herein shown and described.
Description: Latin name of genus and species of plant claimed: Veronica hybrida.

Variety denomination: `Amethyst Plume`.


The present invention relates to a new and distinct cultivar of Veronica plant botanically known as Veronica hybrida and hereinafter referred to by the cultivar name `Amethyst Plume`. The new cultivar originated from an open pollination in 2008in a nursery location in Haarlem, The Netherlands between unknown male and female Veronica hybrida plants. The objective of the breeding program was the development of Veronica cultivars with improved branching, unique flower coloration, and compacthabits.

The new cultivar was selected from the results of the open pollination in 2010 in Haarlem, The Netherlands. Asexual reproduction of the new Veronica by vegetative cuttings in a controlled environment in Haarlem, The Netherlands since the summerof 2010, has shown that the unique features of the Veronica are stable and reproduced true to type in successive generations.


The following are the most outstanding and distinguishing characteristics of this new cultivar when grown under normal horticultural practices in Haarlem, The Netherlands: 1. Lilac-colored flowers in a unique plume-shaped inflorescence; 2. Healthy foliage; 3. Good powdery mildew and rust resistance; and 4. Well-branched, compact growth habit.

Of the many commercially available Veronica cultivars, the most similar in comparison to the new cultivar is `Lavender Plume`, U.S. Plant patent application Ser. No. 13/134,045 (now abandoned). However, in side by side comparisons in Haarlem,The Netherlands, plants of the new cultivar `Amethyst Plume` differ from plants of `Lavender Plume` in at least flower color. Plants of `Amethyst Plume` have a flower color that is not as blue as plants of `Lavender Plume`.

In addition the new cultivar can be compared to the commercially available cultivar `Purpleicious`, U.S. Plant Pat. No. 17,639. However, in side by side comparisons in Haarlem, The Netherlands, plants of the new cultivar `Amethyst Plume`differ from plants of `Purpleicious` in at least the following characteristics: 1. Plants of the new cultivar have a unique plume-shaped inflorescence unlike plants of `Purpleicious`; 2. Plants of the new cultivar are less branched than plants of`Purpleicious`; and 3. Plants of the new cultivar are taller than plants of `Purpleicious`.


The accompanying photographs show, as nearly true as it is reasonably possible to make the same in color illustrations of this type, typical flower and foliage characteristics of the new cultivar. Colors in the photographs differ slightly fromthe color values cited in the detailed description, which accurately describes the colors of `Amethyst Plume`. The plant was field grown for approximately 1 year in Haarlem, The Netherlands in an outdoor nursery location. The plant was transplantedinto a container for photography purposes.

FIG. 3 illustrates a close-up view of the foliage of `Amethyst Plume`.


The new cultivar has not been observed under all possible environmental conditions to date. Accordingly, it is possible that the phenotype may vary somewhat with variations in the environment, such as temperature, light intensity, and daylength, without, however, any variance in genotype.

The chart used in the identification of colors described herein is The R.H.S. Colour Chart of The Royal Horticultural Society, London, England, 2007 edition, except where general color terms of ordinary significance are used. The data whichdefine these characteristics were collected from asexual reproductions carried out in Haarlem, The Netherlands. The plant history was taken in August 2011 on 1-year-old field grown plants which were planted and grown outdoors in daytime temperaturesbetween C. and C. and nighttime temperatures between C. and C. No pinching, growth retardants or photoperiodic treatments were used. Observations were made when the plants were in natural daylightconditions.
