USPP10913P - Clematis plant named `EVIfive` - Google Patents

Abstract

A new large-flowered Clematis cultivar which produces violet purple flowers with a dark red central stripe and yellow anthers. The variety is compact, climbing, clinging and suitable for patio container growth. The variety successfully propagates from softwood cuttings and is suitable for ornamental use in outdoor settings in a variety of climatic conditions. This new and distinct variety has shown to be uniform and stable in the resulting generations from propagation.

Description

SUMMARY OF THE DISCOVERY

The present discovery constitutes a new and distinct variety of Clematis which originated from a controlled crossing between two unnamed seedlings and was discovered in a cultivated area.

The two parents were crossed and the resulting seed was planted in a controlled environment. The new variety is named `EVIfive`.

The objective of the hybridization of this Clematis variety for the nursery industry was to create a new and distinct variety with unique qualities:

1. Large, distinctly colored flowers

2. Orderly plant habit

3. Compact growth and flowering habit, making it suitable for patio container growth.

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 `EVIfive` which distinguish it from all other varieties of which we are aware.

Seedlings from the hybridization were evaluated in a controlled environment. `EVIfive` was selected by Raymond J. Evison and Mogens N. Olesen in their Clematis development program in Domarie Vinieries Les Sauvagees, St. Sampsons, Guernsey, Channel Islands, United Kingdom in 1988.

Asexual reproduction of `EVIfive` 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 1990. This initial and subsequent propagations have demonstrated that the characteristics of `EVIfive` are true to type and are transmitted from one generation to the next.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying color illustrations show as true as is reasonably possible to obtain in color photographs of this type, the typical characteristics of the buds, tepals and leaves of the new variety, with different tepals shown in various stages of maturity. The tepal form, tepal counts, tepal colors, tepal buds, tepal parts, pedicels and the cultivar's foliage are depicted.

DETAILED DESCRIPTION OF THE VARIETY

The following is a detailed description of `EVIfive`, as observed in its growth throughout the flowering period in glasshouses at Domarie Vineries Les Sauvagees, St. Sampsons, Guernsey, Channel Islands, United Kingdom. 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 `EVIone` a variety currently being applied for as Application Ser. No. 08/627,506. Chart 1 details several physical characteristics of the applicant and the comparison varieties.
