plant named ‘Pink Bomb’

Abstract

A new cultivar of Veronica plant, ‘Pink Bomb’, that is characterized by its flowers that are deep pink in color, its compact inflorescences with numerous flowers, and its strong, tall stems making it desirable for cut flower use.

Description

Botanical classification: Veronica hybrid.

Variety denomination: ‘Pink Bomb’.

CROSS REFERENCE TO A RELATED APPLICATION

This application is co-pending with a U.S. Plant Patent Application filed for a plant derived from the same breeding program that is entitled Veronica Plant Named ‘Purple Explosion’ (U.S. Plant patent application Ser. No. 13/815,250).

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Veronica plant of hybrid origin and will be referred to hereinafter by its cultivar name, ‘Pink Bomb’. The new cultivar of Veronica is a hardy herbaceous perennial grown for landscape and cut flower use.

The new cultivar of Veronica was discovered as a naturally occurring whole plant mutation by the Inventor in a seed bed at his nursery in July of 2010 in Haarlem, The Netherlands. The exact parentage is unknown, however the seeds were collected, pooled, and sown from open pollinated plants of ‘Pink Explosion’ (U.S. Plant Pat. No. 22,592), ‘Blue Explosion’ (U.S. Plant Pat. No. 22,497), and ‘Blue Bomb’ (U.S. Plant Pat. No. 22,509).

Asexual propagation of the new cultivar was first accomplished by stem cuttings by the Inventor in August of 2010 in Haarlem, The Netherlands. Asexual propagation by stem cuttings and division has shown that the characteristics of the new cultivar are stable and reproduce 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 ‘Pink Bomb’ as a new and unique cultivar of Veronica.

• • 1. ‘Pink Bomb’ exhibits flowers that are deep pink in color.
  • 2. ‘Pink Bomb’ exhibits compact inflorescences with numerous flowers.
  • 3. ‘Pink Bomb’ exhibits strong, tall (55 to 60 cm in length) stems making it desirable for cut flower use.

‘Pink Bomb’ can be most closely compared to its possible parent plants, ‘Pink Explosion’, ‘Blue Explosion’, and ‘Blue Bomb’. ‘Pink Explosion’ differs from ‘Pink Bomb’ in having lighter pink flowers and in having shorter stems (45 to 50 cm in length). ‘Blue Explosion’ differs from ‘Pink Bomb’ in having blue flowers and in having slightly taller stems (60 to 65 cm in length). ‘Blue Bomb’ differs from ‘Pink Bomb’ in having blue flowers and in having shorter stems (35 to 40 cm in length). ‘Pink Bomb’ can also be compared to ‘Purple Profusion’. ‘Purple Profusion’ differs from ‘Pink Bomb’ in having deep purple-pink flowers and in having taller stems (70 to 75 cm in length).

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 plant about two years in age as grown outdoors in a field in Haarlem, The Netherlands and placed in a pot for the photographs.

The photograph in FIG. 1 provides a side view of ‘Pink Bomb’ in bloom.

The photograph in FIG. 2 provides a close up view of the inflorescences of ‘Pink Bomb’.

The photograph in FIG. 3 provides a close up view of a leaf of ‘Pink Bomb’. The colors in the photograph 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

The following is a detailed description of the new cultivar as observed for a plant about 2-years-old as field grown outdoors in August in Haarlem, The Netherlands. The phenotype of the new cultivar may vary with variations in environmental, climatic, and cultural conditions, as it has not been tested under all possible environmental conditions. The color determination is in accordance with The 2007 R.H.S. Colour Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used.
