A new and distinct cultivar of Veronica plant named ‘Allvspla’, characterized by its upright plant habit; moderately vigorous to vigorous growth habit and moderate growth rate; freely basal branching habit; dark green-colored leaves; freely flowering habit; hemispherical compound inflorescences with numerous light purple-colored flowers; and good performance as a garden plant and cut flower.

Description

Botanical designation: Veronica longifolia X Veronica spicata.

Cultivar denomination: ‘ALLVSPLA’.

PRIOR DISCLOSURES BY INVENTOR/APPLICANT & ASSIGNEE

An European Community Plant Breeder's Rights application for the instant plant was filed by the Assignee, Allplants Holding B.V. of Cuijk, The Netherlands on Sep. 15, 2021, application number 2021/2285. Foreign priority is not claimed to this application.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Veronica plant, botanically known as Veronica longifolia X Veronica spicata, typically grown as a garden plant or cut flower and hereinafter referred to by the name ‘Allvspla’.

The new Veronica plant is a product of a planned breeding program conducted by the Inventor in Naivasha, Kenya. The objective of the breeding program is to create new attractive Veronica plants with attractive flowers, good garden performance and cut flower potential.

The new Veronica plant was discovered and selected by the Inventor as naturally-occurring whole plant mutation of Veronica longifolia X Veronica spicata ‘Allfount’, disclosed in U.S. Plant Pat. No. 31,554, in a controlled nursery environment in Naivasha, Kenya in June, 2018.

Asexual reproduction of the new Veronica plant by terminal stem cuttings in a controlled environment in Naivasha, Kenya, since June, 2018 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 combinations of 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 ‘Allvspla’. These characteristics in combination distinguish ‘Allvspla’ as a new and distinct Veronica plant:

• • 1. Upright plant habit.
  • 2. Moderately vigorous to vigorous growth habit and moderate growth rate.
  • 3. Freely basal branching habit.
  • 4. Dark green-colored leaves.
  • 5. Freely flowering habit.
  • 6. Hemispherical compound inflorescences with numerous light purple-colored flowers.
  • 7. Good performance as a garden plant and cut flower.

Plants of the new Veronica differ primarily from plants of the female parent, ‘Allfount’, primarily in flower color as plants of the new Veronica have light purple-colored flowers whereas plants of ‘Allfount’ have violet-colored flowers.

Plants of the new Veronica can be compared to plants of Veronica longifolia X Veronica spicata ‘Allvwav’, disclosed in a U.S. Plant Patent application filed concurrently. In side-by-side comparisons, plants of the new Veronica differ primarily from plants of ‘Allvwav’ in flower color as plants of the new Veronica have light purple-colored flowers whereas plants of ‘Allvwav’ have white-colored flowers. In addition, plants of the new Veronica are taller than plants of ‘Allvwav’.

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 (FIG. 1) comprises a side perspective view of a typical flowering plant of ‘Allvspla’ grown in a container.

The photographs on the second sheet are close-up views of typical inflorescences (FIG. 2) and typical leaves (FIG. 3) of ‘Allvspla’.

DETAILED BOTANICAL DESCRIPTION

Plants used for the aforementioned photographs and following description were grown in ground beds and 19-cm containers during the summer in a outdoor nursery in Cuijk, The Netherlands and under cultural practices typical of commercial Veronica production. During the production of the plants, day temperatures ranged from 0° C. to 25° C. and night temperatures ranged from −5° C. to 15° C. Plants were 18 months old when the photographs and the description were taken.
