Abstract

A Veronica plant particularly distinguished by a compact, well-branched plant habit, strong stems, strongly-branched, compact inflorescences, a very floriferous blooming habit with re-blooming and easy to grow a strong and well-developed plant in one season, is disclosed.

Description

Genus and species: Veronica sp.
Variety denomination: ‘Pink Explosion’.
BACKGROUND OF THE NEW PLANT
The present invention comprises a new and distinct variety of Veronica, botanically known as Veronica sp., and hereinafter referred to by the variety name ‘Pink Explosion’. ‘Pink Explosion’ was developed through a cross conducted in the summer of 2006 between the female, an un-named proprietary Veronica sp. seedling (unpatented) and the male parent, an un-named proprietary Veronica sp. seedling (unpatented) in Haarlem, The Netherlands. ‘Pink Explosion’ was selected as a single plant in June 2007 and was first propagated in summer 2007 via softwood cuttings in Haarlem, The Netherlands.
‘Pink Explosion’ has been propagated for approximately 4 generations via softwood cuttings and has been found to retain its distinctive characteristics through successive asexual propagations via softwood cuttings.
Plant Breeder's Rights for this variety have not been applied for. ‘Pink Explosion’ has not been made publicly available or sold more than one year prior to the filing date of this application.
SUMMARY OF THE INVENTION
The following are the most outstanding and distinguishing characteristics of this new cultivar when grown under normal horticultural practices in Haarlem, The Netherlands.
    • 1. A compact, well-branched plant habit;
    • 2. Strong stems;
    • 3. Strongly-branched, compact inflorescences;
    • 4. A very floriferous blooming habit with violet buds and re-blooming; and
    • 5. Easy to grow a strong and well-developed plant in one season.
DESCRIPTION OF THE PHOTOGRAPHS
This new Veronica plant is illustrated by the accompanying photographs which show blooms, buds, and foliage of the plant in full color; the colors shown are as true as can be reasonably obtained by conventional photographic procedures. The photographs are of two-year-old plants grown in Haarlem, The Netherlands in July 2010.
FIG. 1 shows a whole plant, including leaves, buds and inflorescence.
FIG. 2 shows a close-up of the inflorescence.
FIG. 3 shows a close-up of a mature leaf.
DESCRIPTION OF THE NEW CULTIVAR
The following detailed descriptions set forth the distinctive characteristics of ‘Pink Explosion’. The data which define these characteristics were collected from asexual reproductions carried out in Haarlem, The Netherlands. The plant history was taken on two-year-old plants grown outdoors in Haarlem, The Netherlands in July 2010. Color readings were taken under natural light. Color references are primarily to The R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.) (2007 edition).
