plant named ‘Zodaque’

Abstract

A new cultivar of hybrid Clematis, ‘Zodaque’, characterized by its free-flowering habit in summer with some re-bloom in summer, its upright facing, semi double pale purple flowers, its climbing growth habit, and its cold hardiness to U.S.D.A. Zone 6.

Description

Botanical classification: Clematis hybrid.

Variety denomination: ‘Zodaque’.

CROSS REFERENCE TO A RELATED APPLICATION

This application is co-pending with a U.S. Plant Patent applications filed for a sibling derived from the same seedlot entitled Clematis Plant Named ‘Zoklako’ (U.S. Plant patent application Ser. No. 12/228,015).

BACKGROUND OF THE INVENTION

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

‘Zodaque’ was selected as unique amongst a group of seedlings that the inventor grew for evaluation 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. ‘Zodaque’ was selected by the inventor in summer of 2002 and derived from seeds collected in 1999 and sown in 2000 from open pollinated Clematis ‘Silver Moon’ (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 2002. 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 for 5 years in Boskoop, The Netherlands. These attributes in combination distinguish ‘Zodaque’ from other cultivar of Clematis known to the inventor.

• • 1. ‘Zodaque’ exhibits upright facing, semi-double flowers that are pale purple in color.
  • 2. ‘Zodaque’ is free flowering in spring with additional flowering in summer.
  • 3. ‘Zodaque’ exhibits a climbing growth habit.
  • 4. ‘Zodaque’ is cold hardy to U.S.D.A. Zone 6.
    ‘Zodaque’ differs from its parent plant in having smaller flowers that are semi-double, ‘Silver Moon’ has single flowers. ‘Zodaque’ differs from its sibling selection, ‘Zoklako’, in flower color and in having semi-double flowers. ‘Zoklako’ has single flowers that have purple margins and centers that are white with purple veins. Close comparisons are Clematis ‘Louise Rowe’ and ‘Belle of Woking’ (both unpatented). ‘Louise Rowe’ differs from ‘Zodaque’ in having flowers that are larger, more violet-blue in color, and double with a ball-shape rather than spreading form. The summer flowers of ‘Louise Rowe’ are also single, rather than semi-double. ‘Belle of Woking’ differs from ‘Zodaque’ in having flowers that are larger, more violet in color, and summer blooms are rarely produced.

BRIEF DESCRIPTION OF THE DRAWING

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

The photograph in FIG. 1 shows the flowering habit in spring.

The photograph in FIG. 2 provides a close-up view of a flower in May and

the photograph in FIG. 3 provides a close-up view of a flower in July.

The photograph in FIG. 4 provides a close-up view of the bracts of a flower in July.

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 ‘Zodaque’ as grown outdoors in full sun 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.
