USPP19305P2 - Veronica plant named ‘YABPIN’ - Google Patents

Abstract

A new cultivar of Veronica of hybrid origin, Veronica ‘YABPIN’, characterized by its compact dense plant habit, its abundance of branched upright flowering stems of self cleaning pink flowers and its resistance to powdery mildew and other fungal diseases.

Description

RELATED APPLICATIONS

This application is co-pending with U.S. Plant patent application No. 09/520,231 filed for a cultivar derived from the same parentage entitled Veronica Plant Named ‘YABBLU’.

Botanical classification: Veronica hybrida.

Cultivar designation: ‘YABPIN’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Veronica, botanically a hybrid known as Veronica ‘YABPIN’ and will be referred to hereafter by its cultivar name, ‘YABPIN’.

The new cultivar was derived from a controlled breeding program conducted by the inventor at his nursery in Congleton, Cheshire, U.K. The overall purpose of the breeding program is to make selections of Veronica plants that exhibit compact plant habits, are floriferous, and exhibit mildew resistance. ‘YABPIN’ was selected as a single plant derived from a cross made in 2002 between an unnamed female parent of a Veronica of unknown parentage and botanical origin and a male a parent selected from the seed strain Veronica spicata ‘Sightseeing’ (not patented).

Asexual reproduction of the new cultivar was first accomplished by terminal stem cuttings in Congleton, Cheshire, U.K. in 2003 by the inventor. It has been determined that the characteristics of this 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, which in combination distinguish ‘YABPIN’ as a new and distinct cultivar of Veronica.

• • 1. ‘YABBLU’ exhibits a compact plant habit due to a high degree of adventititous shoot development.
  • 2. ‘YABBLU’ exhibits a floriferous habit with branched, upright flower stems.
  • 3. ‘YABBLU’ exhibits flowers that are self-cleaning as the flower scape internode length allows for spent flowers to drop; a quality that is not typical for Veronica cultivars.
  • 4. ‘YABBLU’ exhibits resistance to powdery mildew and other fungal diseases.
  • 5. ‘YABPIN’ exhibits pink flowers.

‘YABPIN’ differs from its female parent in being more robust, more upright, and by being more floriferous. ‘YABPIN’ differs from its male parent, a ‘Sightseeing’ selection, in being more reliably perennial, by having denser basal growth and better mildew resistance. The ‘Sightseeing’ hybrids are the closest comparison plants known to the inventor in addition to ‘YABBLU’ from the same breeding program. ‘YABPIN’ differs from ‘YABBLU’ in having pink flowers. ‘YABPIN’ can also be compared to Veronica spicata ‘Glory’ (U.S. Plant Pat. No. 18,932). ‘YABPIN’ is similar to ‘Glory’ in general habit, however ‘YABPIN’ is more compact, has flowers that are self cleaning, has a greater resistance to powdery mildew and other fungal diseases, and has pink flowers rather than blue.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new Veronica. The photographs in FIG. 1 and FIG. 2 were taken in June 2006 of a plant approximately 9 months in age grown from 4 small plugs in a 12 cm container in Banbury, Oxfordshire, U.K.

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

The photograph in FIG. 2 provides a close-up view of the flowers of ‘YABPIN’.

The photograph in FIG. 3 is included to show the adventitious shoot development of plugs grown for 6 months over the winter months from October to April.

The colors in the photographs are as close as possible with the photographic and printing technology utilized. The color values cited in the detailed botanical description accurately describe the colors of the new Veronica.

DETAILED BOTANICAL DESCRIPTION OF THE PLANT

The following is a detailed description of plants of the new cultivar approximately 9 months in age as grown in one-liter containers under greenhouse conditions with ambient light in Cambridgeshire, U.K. 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 2001 R.H.S. Colour Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used.
