Description

Botanical classification: Clematis hybrid.

Variety denomination: ‘Vitiwester’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Clematis if hybrid origin (Viticella Group) and will be referred to hereafter by its cultivar name ‘Vitiwester’. ‘Vitiwester’ is grown as an herbaceous climbing plant for use in the landscape or as a flowering potted plant for the terrace.

‘Vitiwester’ derived from an ongoing breeding program by the Inventor at his nursery in Drunen, The Netherlands. ‘Vitiwester’ was selected as a single unique plant in 2003 and arose from a controlled cross made in 2002 between an unnamed plant of Clematis viticella for the Inventor's breeding program as the female parent and Clematis ‘Westerplatte’ (not patented) as the male parent.

Asexual propagation of the new cultivar was first accomplished by internodial stem cuttings under the direction of the Inventor in Eindhoven, The Netherlands in 2010. Asexual propagation by internodal 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 ‘Vitiwester’ as a unique cultivar of Clematis.

    • 1. ‘Vitiwester’ exhibits deep red velvety flowers, a characteristic that is unique in the Viticella Group of Clematis known by the Inventor.
    • 2. ‘Vitiwester’ exhibits a floriferous blooming habit.
    • 3. ‘Vitiwester’ exhibits typical Viticella Group type foliage.
    • 4. ‘Vitiwester’ reaches a height of 2 to 3 m (6 to 9 ft.).
    • 5. ‘Vitiwester’ exhibits very good resistance to wilt.

The female parent of ‘Vitiwester’, an unnamed plant of Clematis viticella for the Inventor's breeding program, differs from ‘Vitiwester’ in having flowers that are blue-violet in color and smaller in size. The male parent of ‘Vitiwester’, ‘Westerplatte’, is similar to ‘Vitiwester’ in flower coloration. ‘Westerplatte’ differs from ‘Vitiwester’ in having larger flowers and foliage that is typical of large flowering hybrids of Clematis. ‘Vitiwester’ can be most closely compared to the cultivars ‘Madame Julia Correvon’ (not patented) and Clematis viticella ‘Kermesina’ (not patented). ‘Madame Julia Correvon’ differs from ‘Vitiwester’ in having flowers that are lighter and pinker in color that open more widely with tepals more separated, and in having a taller plant height. Clematis viticella ‘Kermesina’ differs from ‘Vitiwester’ in having flowers that are pinker in color with black anthers and in being much taller in height.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new Clematis. The photographs were taken of three year-old plants of ‘Vitiwester’ as grown in a three-gallon container in Drunen, The Netherlands.

The photograph in FIG. 1 shows the plant and foliage habit of ‘Vitiwester’ in bloom.

The photograph in FIG. 2 provides a close-up view of the upper side of a flower of ‘Vitiwester’.

The photograph in FIG. 3 provides a close-up view of the lower side of a flower of ‘Vitiwester’.

The colors in the photographs are as close as possible with the digital photography techniques available, the color values cited in the detailed botanical description accurately describe the colors of the new Clematis.

DETAILED BOTANICAL DESCRIPTION

The following is a detailed description of three year-old plants of ‘Vitiwester’ as grown in three-gallon containers in Drunen, The Netherlands. 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.
