plant named ‘Joca128’

Abstract

A new cultivar of Veronica plant, ‘Joca128’, that is characterized by its dwarf plant habit, its large inflorescences of white flowers, and its floriferous blooming habit with numerous flowering stems and numerous flowers per flowering stem.

Description

Botanical classification: Veronica spicata.

Variety denomination: ‘Joca128’.

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, ‘Joca128’. ‘Joca128’ represents a new herbaceous perennial grown for landscape use.

‘Joca128’ arose from seed collected in autumn of 2009 from an open pollinated plant of Veronica spicata ‘Ulster Blue Dwarf’ (not patented) as the female seed parent. The seeds was sown in 2010 and ‘Joca128’ was selected in autumn of 2011 as a single unique plant amongst the resulting seedlings.

Asexual propagation of the new cultivar was first accomplished by softwood cuttings by the Inventor in winter of 2011 in Boskoop, The Netherlands. Asexual propagation by vegetative 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 ‘Joca128’ as a unique cultivar of Veronica.

• • 1. ‘Joca128’ exhibits a dwarf plant habit.
  • 2. ‘Joca128’ exhibits large inflorescences of white flowers.
  • 3. ‘Joca128’ exhibits a floriferous blooming habit with numerous flowering stems and numerous flowers per flowering stem.

The parent plant of ‘Joca128’, ‘Ulster Blue Dwarf’, differs from ‘Joca128’ in having flowers that are blue in color. ‘Joca128’ can be most closely compared to the Veronica spicata cultivars ‘Verswhite’ (U.S. Plant Pat. No. 24,784) and ‘Icicle’ (not patented). ‘Verswhite’ is similar to ‘Joca128’ in having an upright dwarf plant habit and having flowers that are white in color. ‘Verswhite’ differs from ‘Joca128’ in having smaller leaves and in having fewer flowers per flowering stem. ‘Icicle’ is similar to ‘Joca128’ in having white colored flowers, but differs most significantly from ‘Joca128’ in having a larger, non-dwarf plant habit.

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 ‘Joca128’ as field grown in Haarlem, The Netherlands.

The photograph in FIG. 1 provides a side view of a plant of ‘Joca128’ in bloom.

The photograph in FIG. 2 provides a close-up view of an inflorescence of ‘Joca128’.

The photograph in FIG. 3 provides a close-up view of the foliage of ‘Joca128’.

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

The following is a detailed description of the new cultivar as observed for a plant about one year in age as grown outdoors in 19-cm containers in Haarlem, The Netherlands. The plants were grown under average day temperatures of 16° to 30° C. and average night temperatures of 5° to 20° C. 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.
