Abstract

A new Clematis plant with a compact growth habit, profuse, red flowers, and continuous summer flowering. The variety successfully propagates from softwood cuttings and is suitable for cultivation in commercial nursery culture. This new and distinct variety has shown to be uniform and stable in the resulting generations from asexual propagation from vegetative cuttings.

Description

Botanical classification:

Genus: Clematis.

Species: viticella.

Variety denomination: ‘Evipo084’.

SUMMARY OF THE CLAIMED PLANT

The present invention constitutes a new and distinct variety of Clematis plant which originated from a controlled crossing between the female seed parent, an un-named seedling, and the male pollen parent, an un-named seedling. Both parent varieties are non-patented.

The two parents were crossed during the summer of 2005 and the resulting seeds were planted the following winter in a controlled environment in Guernsey, Channel Islands, United Kingdom. The new variety named ‘Evipo084’ originated as a single seedling from the stated cross.

The new Clematis plant may be distinguished from its female seed parent and male pollen parent by the following characteristics. The female seed parent has an overall growth height of 150 cm, while the new variety grows less vigorous, to 60-80 cm. The male seed parent has Red 53A tepals while the new variety has Red-Purple Group 59A colored tepals.

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

- 1. Uniform and abundant red flowers;
- 2. Vigorous and compact growth, making the variety suitable for container culture; and
- 3. Improved disease resistance.

This combination of qualities was lacking in Clematis plants that were in commercial cultivation and the qualities have been substantially achieved in the new variety.

‘Evipo084’ was selected by Mogens N. Olesen and Raymond J. Evison in their Clematis development program in the Channel Islands, United Kingdom in 2006. Asexual reproduction of ‘Evipo084’ by means of vegetative cuttings and traditional layering was first performed by Mogens N. Olesen and Raymond J. Evison in the nursery during the summer of 2006. This initial and subsequent asexual propagations have demonstrated that the characteristics of ‘Evipo084’ 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, flowers, leaves, and stems, of ‘Evipo084’.

Specifically illustrated in FIG. 1 of the drawings is an open flower, tepals detached showing reproductive flower parts, and flower buds.

FIG. 2 shows leaves and stems.

Illustrated plants are 2 years of age.

DETAILED DESCRIPTION OF THE VARIETY

The following is a detailed description of ‘Evipo084’, as observed in its growth throughout the flowering period in Denmark. 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, except where common terms of color are used.

For a comparison, several physical characteristics of the Clematis variety ‘Evipo069’ described and illustrated in U.S. Plant Pat. No. 27,714 are compared to ‘Evipo084’ in Chart 1.
