CROSS REFERENCE TO A RELATED APPLICATION

This application claims priority to European Community Plant Variety Office (CPVO) Plant Breeder's Rights Application No. 2023/1037 filed on May, 10, 2023, 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 ‘EviGsy151’. ‘EviGsy151’ is an herbaceous perennial grown for use as a landscape and container plant.

‘EviGsy1l51’ derived from an ongoing breeding program by the Inventor at his nursery in Guernsey, United Kingdom. The goal of the program was to select a new cultivar of Clematis with a compact plant habit, a floriferous blooming habit, and uniquely colored large flowers. ‘EviGsy151’ was selected as a single unique plant in May of 2019 and arose from a controlled cross made in June of 2014 between unnamed proprietary plants of Clematis patens x Clematis viticella from the Inventor's breeding program as both the female and male parents.

Asexual propagation of the new cultivar was first accomplished by softwood stem cuttings under the direction of the Inventor in May of 2019 in Guernsey, United Kingdom. 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 ‘EviGsy151’ as a unique cultivar of Clematis.

• • 1. ‘EviGsy151’ exhibits large sized flowers.
  • 2. ‘EviGsy151’ exhibits vibrant purple-blue flowers with a vertical pink central band on the tepals, and vibrant red anthers.
  • 3. ‘EviGsy151’ exhibits a compact plant habit.
  • 4. ‘EviGsy151’ exhibits a very floriferous blooming habit.
  • 5. ‘EviGsy151’ exhibits good vigor with ease of growth.
  • 6. ‘EviGsy151’ exhibits good suitability for growing in gardens and containers.

The female parent of ‘EviGsy151’ differs from ‘EviGsy151’ in having flower tepals that are less blue in color and a less compact plant habit. The male parent of ‘EviGsy151’ differs from ‘EviGsy151’ in having flower centers with yellow anthers. ‘EviGsy151’ can be most closely compared to the Clematis cultivars ‘Evipo041’ (U.S. Plant Pat. No. 24,171) and ‘Evipo019’ (U.S. Plant Pat. No. 16,069). ‘Evipo041’ is similar to ‘EviGsy151’ in having purple flowers with a vertical center band on the tepals and a center of red stamens. ‘Evipo041’ differs from ‘EviGsy151’ in having flowers that are less blue in color and have a less compact plant habit. ‘Evipo019’ is similar to ‘EviGsy151’ in plant habit and in having a center of red stamens. ‘Evipo019’ differs from ‘EviGsy151’ in having flower tepals that have less red tones and lacks a vertical central band.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying color photographs illustrate the overall appearance and distinct characteristics of the new Clematis. The photographs were taken of a 2.5-year-old plant as grown in a conventional greenhouse in 17-cm containers in Guernsey, United Kingdom.

The photograph in FIG. 1 provides a side view of ‘EviGsy151’ in bloom.

The photograph in FIG. 2 provides a close-up view of a mature flower (top) and young flower (bottom) of ‘EviGsy151’.

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.
