plant named ‘Zojapur’

Abstract

A new cultivar of hybrid Clematis, ‘Zojapur’, characterized by its nodding open campanulate-shaped flowers that are deep purple in color with lighter red-purple centers, its free flowering habit in spring with free flowering re-bloom in summer when pruned, its climbing growth habit, and its cold hardiness to U.S.D.A. Zone 5.

Description

Botanical classification: Clematis hybrid.

Variety denomination: ‘Zojapur’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Clematis, botanically of hybrid origin and classified in the Jackmanii Group, and will be referred to hereafter by its cultivar name, ‘Zojapur’. ‘Zojapur’ is grown as an herbaceous climber for landscape use and for use as a flowering potplant for the terrace.

‘Zojapur’ derived from an ongoing breeding program by the inventor in his nursery in Boskoop, The Netherlands. The goal of the selection was to select a hardy climber with uniquely colored flowers that could be grown for different purposes in the garden. ‘Zojapur’ was selected in summer of 2003 and arose from a controlled cross made in 1999 between the female parent, Clematis ‘Mrs. George Jackman’ (not patented) and the male parent, Clematis ‘Walenburg’ (not patented).

Asexual reproduction of the new cultivar was first accomplished by internodial stem cuttings under the direction of the inventor in Boskoop, The Netherlands in 2003. The characteristics of this cultivar have been determined to be 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 as grown outdoors ‘Zojapur’ from other cultivars of Clematis known to the inventor.

• • 1. ‘Zojapur’ exhibits nodding flowers that are deep purple in color with a center section that is lighter and red-purple in color.
  • 2. ‘Zojapur’ is free flowering in spring and repeats its free flowering habit in summer when pruned after spring bloom.
  • 3. ‘Zojapur’ exhibits a climbing growth habit.
  • 4. ‘Zojapur’ is cold hardy to U.S.D.A. Zone 5.
    ‘Zojapur’ differs from its female parent, ‘Mrs. George Jackman’, in having purple colored flowers rather than white and in having a stronger habit and differs from its male parent, ‘Walenburg’ in having much larger flowers and flowers that are purple in color rather than mauve pink. Close comparisons are Clematis ‘Jackmanii’ and ‘Star of India’ (both unpatented). ‘Jackmanii’ differs from ‘Zojapur’ in having flowers that are more violet-blue in color with tepals that are less rounded and have a dark purple tint at the base. ‘Star of India’ differs in having flowers that are violet-blue in color with red-purple centers, tepals with a dark purple tint at the base and stamens that are twisted.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new Clematis. The photographs were taken of a plant of ‘Zojapur’ as grown in a trial bed for 3 years in Boskoop, The Netherlands.

The photograph in FIG. 1 shows the flowering habit.

The photograph in FIG. 2 provides a close-up view of the outer surface of the flower and flower form.

The photograph in FIG. 3 provides a close-up view of the upper surface of the flower and pistils and stamens (one tepal is removed).

The photograph in FIG. 4 provides a view of a flower bud and leaf.

The photograph in FIG. 5 provides a close-up view of a seedhead.

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 3 year-old plants of ‘Zojapur’ as grown outdoors in full sun to semi-shade in a test plot in Boskoop, 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 2001 R.H.S. Colour Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used.
