Title: Clematisplant named ‘Evipo098’

Description:
Botanical classification: Genus:  Clematis . Species:  viticella.    
     Variety Denomination: ‘Evipo098’. 
     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 ‘Evipo098’ 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 Red-Purple Group 65B tepals while the new variety has tepals with coloration of Red-Purple Group 62C with intonations of Red-Purple Group 70A. The male seed parent has white tepals while the new variety has red-purple 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-purple 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. 
     ‘Evipo098’ 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 ‘Evipo098’ 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 ‘Evipo098’ 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 ‘Evipo098’. 
       Specifically illustrated in  FIG. 1  of the drawings is an open flower, tepals detached revealing reproductive flower parts, and a flower bud. 
         FIG. 2  shows mature and juvenile leaves, and bare stems. 
       Illustrated plants are 2 years of age. 
     
    
    
     DETAILED DESCRIPTION OF THE VARIETY 
     The following is a detailed description of ‘Evipo098’, as observed in its growth throughout the flowering period in Marion County Oreg. 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 ‘Evipo027’ described and illustrated in U.S. Plant Pat. No. 27,281 are compared to ‘Evipo098’ in Chart 1.
