plant named ‘Bailtextwo’

Abstract

A new cultivar of Vitex plant named ‘Bailtextwo’ that is characterized by its compact and rounded to upright habit, its prolific flowering habit that produces flowers that are vibrant purple-pink in color, its freely branched habit and its excellent vigor.

Description

Botanical classification: Vitex agnus-castus.

Variety denomination: ‘Bailtextwo’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Vitex agnus-castus. The new Vitex will hereafter be referred to by its cultivar name, ‘Bailtextwo’. ‘Bailtextwo’ is a new cultivar of Vitex agnus-castus 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. ‘Bailtextwo’ arose from open pollination of Vitex agnus-castus ‘Flora Ann’ (not patented) as the female parent. The male parent is therefore unknown. ‘Bailtextwo’ was selected as a single unique plant from the progeny of the open-pollination in 2015 after evaluation for growth habit, foliage, and flower characteristics.

Asexual propagation of the new cultivar was first accomplished by semi-hardwood stem cuttings by one of the Inventors in Watkinsville, Ga. in 2015. 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. The attributes in combination distinguish ‘Bailtextwo’ as a unique cultivar of Vitex.

• • 1. ‘Bailtextwo’ exhibits a compact and rounded to upright habit.
  • 2. ‘Bailtextwo’ exhibits a prolific flowering habit that produces flowers that are vibrant purple-pink in color.
  • 3. ‘Bailtextwo’ exhibits a freely branched habit.
  • 4. ‘Bailtextwo’ exhibits excellent vigor.

The female parent plant differs from ‘Bailtextwo’ in having flowers that are less vibrant in color, flower stalks that are shorter in height and in being less vigorous. ‘Bailtextwo’ can be most closely compared to Vitex agnus-castus cultivars ‘V07-SC-OP-4’ (U.S. Plant Pat. No. 27,374) and ‘PIIVAC-1’ (U.S. Plant Pat. No. 25,914). ‘V07-SC-OP-4’ differs from ‘Bailtextwo’ in having flower stalks that are shorter in height, a less vigorous growth habit, a smaller plant size, and a more compact plant habit. ‘PIIVAC-1’ differs from ‘Bailtextwo’ in having flowers that are purple in color and darker green foliage.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new Vitex. The photographs in the figures were taken of a plant 3 years in age as grown in a trial garden in Watkinsville, Ga.

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

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

The colors in the photographs are as close as possible with the digital photography and printing techniques utilized and the color codes in the detailed botanical description accurately describe the colors of the new Vitex.
