Description

Botanical classification: Clematis hybrid.

Variety denomination: ‘Zo14100’.

CROSS REFERENCE TO A RELATED APPLICATION

This application claims priority to European Community Plant Variety Office (CPVO) Plant Breeder's Rights Application No. 2019/0728 filed on Mar. 18, 2019, the entire contents of which is incorporated by reference herein.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Clematis of hybrid origin and will be referred to hereafter by its cultivar name ‘Zo14100’. ‘Zo14100’ is a herbaceous perennial grown for use as a landscape plant.

The Inventor discovered the new cultivar in August of 2014 as a naturally occurring whole plant mutation of Clematis ‘Tangutica’ (not patented, used in the trade as a cultivar even though it is also the species name) in a seedling block at a nursery in Boskoop, The Netherlands. The seedling block had been sown with seed collected from numerous seedling plants of Clematis ‘Tangutica’, therefore the exact parent plant is unknown.

Asexual propagation of the new cultivar was first accomplished by softwood stem cuttings under the direction of the Inventor in Boskoop, The Netherlands in 2015. Asexual propagation by softwood stem cutting 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 Clematis ‘Zo14100’ as a unique cultivar of Clematis.

• • 1. ‘Zo14100’ exhibits a dwarf plant habit.
  • 2. ‘Zo14100’ exhibits a non-climbing habit.
  • 3. ‘Zo14100’ exhibits a very floriferous blooming habit.
  • 4. ‘Zo14100’ exhibits cold hardiness at least to U.S.D.A. Zone 5.

The potential parent plants of ‘Zo14100’ all differ from ‘Zo14100’ in having a climbing plant habits and in being less floriferous. ‘Zo14100’ can be most closely compared to the Clematis cultivars ‘Kugotia’ (U.S. Plant Pat. No. 10,952) and ‘Bill MacKenzie’ (not patented). Both are similar to ‘Zo14100’ in having yellow color flowers and in cold hardiness. Both differ from ‘Zo14100’ in being taller in height with a climbing habit and in having flowers that are larger in size with dark purple stamen connectives.

STATEMENT DESIGNATING A GRACE PERIOD UNDER 102(B)(1)

The Applicant claims prior art exemption under 35 U.S.C. 102(b)(1) for disclosure and/or sales prior to the filing date but less than one year prior to the effective filing date if need be. Information about the claimed plant was obtained from a direct or indirect disclosure from the Inventor; including but not limited to disclosures on websites by J Van Zoest, Plantarium, Plantipp, Thompson and Morgan, Taylors Clematis, Brushwood Nursery, and Waitrose Garden.

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 a two-year-old plant as grown outdoors in a 2-liter rose container in Boskoop, The Netherlands.

The photograph in FIG. 1 provides a view of ‘Zo14100’ in bloom.

The photograph in FIG. 2 provides a close-up view of the flowers and seed heads of ‘Zo14100’.

The photograph in FIG. 3 provides a close-up view of a cross section of a flower of ‘Zo14100’.

The colors of 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 two-year-old plants as grown outdoors in 2-Liter rose containers in Boskoop, The Netherlands.
