plant named ‘Verpurg’

Abstract

A new cultivar of Veronica plant named ‘Verpurg’ that is characterized by its compact and dwarf plant habit, its numerous flowering stems, its re-blooming habit resulting in a long bloom season, its flowers that are intense violet-purple in color, and its strong flower stems.

Description

Botanical classification: Veronica spicata.

Cultivar designation: ‘Verpurg’.

CROSS REFERENCE TO A RELATED APPLICATION

This application is related to U.S. Plant Patent for a plant derived from the same breeding program that is entitled Veronica Plant Named ‘Verspi’ (U.S. Plant Pat. No. 29,780).

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Veronica spicata and will be referred to hereafter by its cultivar name, ‘Verpurg’. ‘Verpurg’ represents a new herbaceous perennial grown for landscape use.

‘Verpurg’ arose from open pollination of Veronica ‘Verspi’ as the female parent. ‘Verpurg’ originated as a seedling that arose from seed planted from open pollination of Veronica ‘Verspi’ in 2016. The male parent is therefore unknown. ‘Verpurg’ was selected as a single unique plant in 2018 from amongst the resulting seedlings.

Asexual propagation of the new cultivar was first accomplished by stem cuttings by the Inventor in July of 2019 in Haarlem, The Netherlands. Asexual propagation by stem cuttings has determined that the characteristics of the new cultivar are stable and are reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and represent the characteristics of the new cultivar. These attributes in combination distinguish ‘Verpurg’ as a unique cultivar of Veronica.

• • 1. ‘Verpurg’ exhibits a compact and dwarf plant habit.
  • 2. ‘Verpurg’ exhibits numerous flowering stems.
  • 3. ‘Verpurg’ exhibits a re-blooming habit resulting in a long bloom season.
  • 4. ‘Verpurg’ exhibits flowers that are intense violet-purple in color.
  • 5. ‘Verpurg’ exhibits strong flower stems.

The female parent of ‘Verpurg’, ‘Verspi’, is similar to ‘Verpurg’ in in having compact, dwarf plant habit and a floriferous blooming habit. ‘Verspi’ differs from ‘Verpurg’ in having flowers that are pink in color. ‘Verpurg’ can be compared to the Veronica spicata cultivar ‘Purpleicious’ (U.S. Plant Pat. No. 17,639). ‘Verspi’ is similar to ‘Verpurg’ in having compact, dwarf plant habit and a floriferous blooming habit. ‘Verspi’ differs from ‘Verpurg’ in having flowers that are pink in color. ‘Purpleicious’ is similar to ‘Verpurg’ in having flowers that are purple in color. ‘Purpleicious’ differs from ‘Verpurg’ in having a shorter bloom period (commences bloom later in season), in being taller in height (less compact), and in having shorter flower stems.

STATEMENT REGARDING PRIOR DISCLOSURES BY THE INVENTOR

The Applicant asserts that no publications or advertisements relating to sales, offers for sale, or public distribution occurred more than one year prior to the effective filing date of this application. Any information about the claimed plant would have been obtained from a direct or indirect disclosure from the Inventor. The Applicant claims a prior art exemption under 35 U.S.C. 102(b)(1) for disclosure and/or sales prior to the filing date but less than one year prior to the effective filing date. Disclosures include but may not be limited to a website listing by Concept Plants, the breeder's representative for licensing (Concept Plants does not sell plants) and Kientzler (a licensee of Concept Plants that produces unrooted cuttings for growers).

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new Veronica. The photographs were taken of a one-year-old plant of ‘Verpurg’ as field grown in Haarlem, The Netherlands and placed in a container for the photograph.

The photograph in FIG. 1 provides a side view of a plant of ‘Verpurg’ in bloom.

The photograph in FIG. 2 provides a close-up view of an inflorescence and leaves of ‘Verpurg’.

The 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.

DETAILED BOTANICAL DESCRIPTION
