Clematis variety ‘EVIpo002’

Abstract

A new Clematis cultivar which is well suited to propagation in glasshouses. With a compact growth habit and profuse, Red-Purple flowers which have good color retention. 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 asexual propagation.

Description

Botanical classification: Clematis viticella.

Variety denomination: ‘EVIpo002’.

Commercial classification: Early-large flowering cultivar.

SUMMARY OF THE DISCOVERY

The present discovery constitutes a new and distinct variety of Clematis which originated from an uncontrolled pollination of two unknown Clematis plants. The claimed plant was discovered in a cultivated area. The new variety is named ‘EVIpo002’.

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 such as:

• • 1. Large full form red-purple flowers.
  • 2. Compact Growth.
  • 3. Yellow flower center.
  • 4. Strong flower color with good color retention.

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 ‘EVIpo002’ which distinguish it from all other varieties of which we are aware.

Evaluations were conducted on the discovered seeling in a controlled environment. ‘EVIpo002’ 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 1997.

Asexual reproduction of ‘EVIpo002’ 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 May 1997. This initial and subsequent propagations have demonstrated that the characteristics of ‘EVIpo002’ 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 ‘EVIpo002’, as observed in its growth throughout the flowering period in glasshouses at Domarie Vineries Les Sauvagees, St. Sampsons, Guernsey, Channel Islands, United Kingdom. Plants were cultivated for two years in two 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, 2001.

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