Clematis variety ‘EVIpo013’

Abstract

A new Clematis cultivar which is well suited to propagation in glasshouses. With a tall growth habit, profuse, purple flowers, and continuous summer flowering. The variety successfully propagates from softwood cuttings and is suitable for cultivation in commercial glasshouses. This new and distinct variety has shown to be uniform and stable in the resulting generations from propagation.

Description

Botanical classification: Genus: Clematis. Species: viticella.

Variety denomination: ‘EVIpo013’.

SUMMARY OF THE INVENTION/DISCOVERY

The present discovery constitutes a new and distinct variety of Clematis which originated from uncontrolled pollination between an unknown pollen parent and the seed parent, an unnamed, non-patented, plant. The new variety, ‘EVIpo013’, resulted from germinating seeds of the chance pollination.

The main characteristic that distinguishes ‘EVIpo013’ from the seed parent variety is that the unnamed seed parent has a Violet Blue flower color. The same of ‘EVIpo013’ is Purple Group 79B. The objective of the cultivation of this Clematis variety for commercial glasshouse and nursery culture was to create a new and distinct variety with:

• • 1. Non-clinging habit;
  • 2. Profusion of semi-nodding purple flowers;
  • 3. Suitability for garden situations;
  • 4. Winter hardiness in zones 3 to 9.

These qualities required improvement in Clematis varieties that were in commercial cultivation and the objectives have been substantially achieved in the new variety, as evidenced by the unique combination of characteristics that are present in ‘EVIpo013’ which distinguish it from all other varieties of which we are aware.

The seeds, collected from the unnamed seed parent plant, were germinated and evaluations were conducted of the resulting Clematis plants in a controlled environment.

‘EVIpo013’ was selected by Raymond J. Evison and Mogens N. Olesen in their Clematis development program in Domarie Vineries Les Sauvagees, St. Sampsons, Guernsey, Channel Islands, United Kingdom in July, 1998.

Asexual reproduction of ‘EVIpo013’ by cuttings was first done by Raymond J. Evison and Mogens N. Olesen in Domarie Vineries Les Sauvagees, St. Sampsons, Guernsey, Channel Islands, United Kingdom in July 1998. This initial and subsequent propagations have demonstrated that the characteristics of ‘EVIpo013’ are true to type and are transmitted from one generation to the next.

DETAILED DESCRIPTION OF THE VARIETY

The following is a detailed description of ‘EVIpo013’, as observed in its growth throughout the flowering period in glasshouses at Domarie Vineries Les Sauvagees, St. Sampsons, Guernsey, Channel Islands, United Kingdom. Observed plants are 2 years of age, and were cultivated in 2 liter pots. Certain phenotypical characteristics of the variety may vary under different environmental, cultural, agronomic, seasonal, and climatic conditions. Color references are made using The Royal Horticultural Society (London, England) Colour Chart, 1995.

For a comparison, the nearest existing Clematis variety is ‘Alionushka’, non-patented. Chart 1 details several physical characteristics of ‘EVIpo013’ and the comparison variety.

  • • Size.—15 to 20 mm in length.
    • Bud form.—Ovoid.
    • Bud length.—15 to 20 mm.
    • Bud diameter.—10 to 12 mm.
    • Bud color.—Purple Group 79C; Purple Group 79C at ¼ open.
    • Tepals.—Purple Group 79C.
    • Peduncle.—Surface: Smooth. Length: 120 to 180 mm. Color: Green Group 137A. Strength: Semi-nodding.
    • Receptacle.—None.
    • Borne.—Compound dichasial cymes.
• Flower bloom:
  • • Size.—60 to 80 mm in diameter.
    • Form.—Long companulate, with tepals slightly reflexing.
    • Depth.—30 to 50 mm.
    • Color.—Upon opening, the upper tepal surface is Purple Group 79B. Upon opening, the lower tepal is Purple Group 79B. After opening, the main color of the upper tepal surface is Purple Group 79B. After opening, the main color lower surface is Purple Group 79B. The base of the tepals is Purple Group 79B. Purple Group 79C, with a longitudinal bar of Purple Group 79B along the middle zone. As the flower ages it will fade to Purple Group 79C, with tepal margins fading to a light Purple Group 79D.
    • General tonality.—Purple.
    • Variations.—None.
    • Fragrance.—None.
    • Bloom duration.—On the plant, 7 to 10 days. As a cut flower, 2 to 4 days.
• Tepals:
  • • Tepal count.—Single. Average range: 4.
