| Abstract: |
A new Clematis cultivar which is well suited to propagation is glasshouses. With a tall growth habit, profuse, white flowers, and continuous summer flowering. 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: |
It is claimed:
1. We claim a new and distinct variety of clematis plant, as herein shown and described, due to its abundant white flowers with good keepability, attractive long lasting foliageand 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 for distribution in the floral industry. |

SUMMARY OF THE INVENTION
Botanical classification: Clematis 1Genus--Clematis. Species--viticella.
Variety denomination: `EVIpo009`.
Commercial classification: Early, large-flowering cultivar.
The present invention constitutes a new and distinct variety of Clematis which originated from a chance pollination between the female seed parent an unnamed, non-patented plant and an unknown male pollen parent plant.
`Evipo009` may be distinguished from its female seed parent primarily by flower color.
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 that this variety has: 1. Large white flowers; 2. Compact growth; 3. Red/Brownflower 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`EVIpo009` which distinguish it from all other varieties of which we are aware.
The seeds from the aforementioned chance pollination were germinated and evaluations of the resulting seedling plants were conducted in a controlled environment. As a result, `EVIpo009` was selected by Raymond J. Evison and Mogens N. Olesen intheir Clematis development program in Domarie Vineries Les Sauvagees, St. Sampsons, Guernsey, Channel Islands, United Kingdom in April 1997.
Asexual reproduction of `EVIpo009` 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 June 1997. This initial and subsequentpropagations have demonstrated that the characteristics of `EVIpo009` are true to type and are transmitted from one generation to the next.
BRIEF DESCRIPTION OF THE DRAWING
The accompanying color illustration show as true as is reasonably possible to obtain in color photographs of this type:
FIG. 1.1 Stem with new growth and mature leaves, showing the attachment of petioles;
FIG. 1.2 Mature compound leaf;
FIG. 1.3 Flower buds closed;
FIG. 1.4 Open Flower, lower part, and tepals, detached;
FIG. 1.5 Open flower viewed from the side and above.
DETAILED DESCRIPTION OF THE VARIETY
The following is a detailed description of `EVIpo009`, 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, 1995.
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 `EVIpo009` and thecomparison variety.
