Clematis plant named ‘EVIpo008’

Abstract

A new Clematis cultivar which is well suited to propagation in glasshouses. With a tall growth habit, profuse, lavender double 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: ‘EVIpo008’.

COMMERCIAL CLASSIFICATION

Early flowering, large flowered cultivar.

SUMMARY OF THE INVENTION

The present invention constitutes a new and distinct variety of Clematis which originated from a chance pollination between the female plant ‘EVItwo’, described and illustrated in U.S. Plant Pat. No. 10,167 dated Dec. 30, 1997, and an unknown male pollen parent plant.

The new clematis may be distinguished from its female seed parent, ‘EVItwo’, by the following combination of characteristics:

• • 1. Flowers of ‘EVItwo’ are white, while those of ‘EVIpo008’ are lavender purple.
  • 2. Flowers of ‘EVItwo’ have 12 tepals on average, while flowers of ‘EVIpo008’ have 40 to 60 tepals.

The seed resulting from the chance pollination was planted in a controlled environment. The resulting seedlings were evaluated.

The objective of the selection of this Clematis variety for commercial glasshouse and nursery culture was to create a new and distinct variety with unique qualities that this variety has:

• • 1. Exceptional violet colored flowers;
  • 2. Flowers that have double tepalage;
  • 3. Plants which re-flower readily;
  • 4. Desirable glasshouse production characteristics such as ease of propagation and good flowering characteristics.

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 ‘EVIpo008’ which distinguish it from all other varieties of which we are aware.

The seeds from the aforementioned chance pollination were germinated and evaluations of the resulting seedling plants were conducted in a controlled environment. As a result, ‘EVIpo008’ 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 April 1993.

Asexual reproduction of ‘EVIpo008’ 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 April 1995. This initial and subsequent propagations have demonstrated that the characteristics of ‘EVIpo008’ 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 ‘EVIpo008’, 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 were cultivated for a period of 24 months in 2 liter containers. 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, 2001.

For a comparison, the nearest existing Clematis variety is ‘Belle of Woking’ non-patented variety. Chart 1 details several physical characteristics of ‘EVIpo008’ and the comparison variety.
