Abstract

A new cultivar of Vitex plant named ‘Bailtexone’ that is characterized by its compact, rounded to upright growth habit, its foliage that is olive green in color on the upper surface and light purple in color on the lower surface, its flowers that are violet in color.

Description

Botanical classification: Vitex trifolia x Vitex agnus-castus.
Variety denomination: ‘Bailtexone’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Vitex trifolia. The new Vitex will hereafter be referred to by its cultivar name, ‘Bailtexone’. ‘Bailtexone’ is a new cultivar of chaste tree grown for use as an ornamental landscape plant.
The new cultivar was derived from a controlled breeding program conducted by the Inventors in Watkinsville, Ga. The objective of the breeding program is to develop a new cultivar of Vitex that is cold hardy with purple foliage. ‘Bailtexone’ arose from a cross-made in 2012 between Vitex trifolia ‘Purpurea’ (not patented) as the female parent and unnamed and unpatented plant of Vitex agnus-castus as the male parent. ‘Bailtexone’ was selected as a single unique plant in 2013 from amongst the seedlings derived from the above cross.
Asexual propagation of the new cultivar was first accomplished by semi-hardwood stem cuttings by one of the Inventors in Watkinsville, Ga. in 2014. Asexual propagation by semi-hardwood 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 ‘Bailtexone’ as a unique cultivar of Vitex.
  • 1. ‘Bailtexone’ exhibits a compact, rounded to upright growth habit.
  • 2. ‘Bailtexone’ exhibits foliage that is olive green in color on the upper surface and light purple in color on the lower surface.
  • 3. ‘Bailtexone’ exhibits flowers that are violet in color.
‘Purpurea’, the female parent of ‘Bailtexone’, differs from ‘Bailtexone’ in being hardy in U.S.D.A. Zones 9 to 11; less cold hardy than ‘Bailtexone’. The male parent of ‘Bailtexone’ differs from ‘Bailtexone’ in being a tree with a much taller plant height and a vase shaped plant habit, and in having compound palmate shaped leaves that are grey-green in color on both surfaces. ‘Bailtexone’ can also be compared to the Vitex cultivar ‘PIIVAC-I’ (U.S. Plant Pat. No. 25,914). ‘PIIVAC-I’ differs from ‘Bailtexone’ in having foliage that is dark green in color and flowers that are blue in color.
BRIEF DESCRIPTION OF THE DRAWINGS
The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new ‘Bailtexone’. The photographs were taken of a 4 year-old plant of ‘Bailtexone’ as grown outdoors in the ground in Watkinsville, Ga.
The photograph in FIG. 1 provides a side view of ‘Bailtexone’ in bloom.
The photograph in FIG. 2 provides a close-up view of the flowers and foliage coloration of ‘Bailtexone’.
The colors in the photographs are as close as possible with the photographic and printing technology utilized and the color values cited in the Detailed Botanical Description accurately describe the colors of the new Vitex.
DETAILED BOTANICAL DESCRIPTION
The following is a detailed description of 4 year-old plants of the new cultivar as grown outdoors in the ground in Watkinsville, Ga. 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 2015 R.H.S. Colour Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used.
