Abstract: A new Clematis cultivar with compact growth habit, profuse, white and violet blue flowers which is well suited to propagation in glasshouses. 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.
Claim: We claim:

1. A new and distinct variety of Clematis plant, substantially as herein shown and detailed, as a distinct and novel Clematis variety due to its abundant white and violet blue flowerswith good keepability, attractive long lasting foliage and compact growth, year round flowering under glasshouse conditions, suitability for production from softwood cuttings in pots, durable flowers and foliage which make the variety suitable fordistribution in the floral industry.
Description: Botanical classification: Clematis l. Genus--Clematis. Species--hybrid.

Variety denomination: `Evipo003`.

Commercial classification: Early flowering cultivar.


The present invention constitutes a new and distinct variety of Clematis which originated from a controlled crossing between the female parent `Evitwo` described and illustrated in U.S. Plant Pat. No. 10,167 dated Dec. 30, 1997, and the maleparent, an unnamed, unpatented plant of Clematis chrysocoma a non-patented clematis.

The new clematis may be distinguished from its female seed parent, `Evitwo`, by the following combination of characteristics: 1. `Evipo003` is a single flowered variety, whereas `Evitwo` is a double flowered variety. 2. While flowers of`Evitwo` are pure white, `Evipo003` has violet intonations in the tepals.

The new clematis may be distinguished from its male pollen parent, Clematis chrysocoma, by the following combination of characteristics: 1. Clematis chrysocoma has pink flowers, while `Evipo003` has white and violet blue flowers. 2. `Evipo003`has a greater flower size than Clematis chrysocoma.

The two parents were crossed and the resulting seed was planted in a controlled environment. The new variety is named `Evipo003`.

The objective of the hybridization 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. Profuse flowering habit. 2. White flowers withslight violet blue tones and a yellow center.

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`Evipo003` which distinguish it from all other varieties of which we are aware.

The seeds from the aforementioned hybridization were germinated and evaluations of the resulting seedling plants were conducted in a controlled environment. As a result, `Evipo003` was selected by Raymond J. Evison and Mogens N. Olesen in theirClematis development program in Domarie Vineries Les Sauvagees, St. Sampsons, Guernsey, Channel Islands, United Kingdom in April 1998.

Asexual reproduction of `Evipo003` 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 1998. This initial and subsequent asexualpropagations have demonstrated that the characteristics of `Evipo003` are true to type and are transmitted from one generation to the next.


The accompanying color illustrations show as true as is reasonably possible to obtain in color photographs of this type:

FIG. 1 Open flower upper side;

FIG. 2 Open flower, upper and lower surface;

FIG. 3.1 Stem, leaves, bud at 1/4 opening, bud closed;

FIG. 3.2 Mature stem and leaves;

FIG. 3.3 Juvenile stem and leaves.


The following is a detailed description of `Evipo003`, 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 werecultivated 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 RoyalHorticultural Society (London, England) Colour Chart, 2001.

For a comparison, the nearest existing Clematis variety is `Evirin`, a patented variety described and illustrated in U.S. Plant Pat. No. 12,838 issued on Aug. 13, 2002. Chart 1 details several physical characteristics of `Evipo003` and thecomparison variety.
