plant named ‘Evipo115’

Abstract

A new Clematis plant with a compact growth habit, profuse, purple 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: ‘Evipo115’.

This application claims priority to Plant Breeder's Rights Application Number 2021/2369, which was filed at the Community Plant Variety Rights Office in the European Union on Sep. 24, 2021, the contents of which are hereby incorporated by reference for all purposes.

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 2007 and the resulting seeds were planted the following winter in a controlled environment in Guernsey, Channel Islands, United Kingdom. The new variety named ‘Evipo115’ 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 grows to 60 cm in one season while the new variety grows only to 15 cm in one season. The male seed parent has yellow anthers while the new variety has Greyed-Purple Group N186A anthers.

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 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.

‘Evipo115’ was selected by Mogens N. Olesen and Raymond J. Evison in their Clematis development program in the Channel Islands, United Kingdom in 2008. Asexual reproduction of ‘Evipo115’ 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 2008. This initial and subsequent asexual propagations have demonstrated that the characteristics of ‘Evipo115’ 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 ‘Evipo115’.

Specifically illustrated in FIG. 1 of the drawings are open flowers viewed from above and underneath, and the tepals detached revealing reproductive flower parts.

FIG. 2 shows leaves, a stem bearing clusters of open flowers and flower buds. Illustrated plants are 2 years of age.

DETAILED DESCRIPTION OF THE VARIETY

The following is a detailed description of ‘Evipo115’, as observed in its growth throughout the flowering period in Odense. Observed plants were cultivated for a period of 24 months in 24 cm containers, outdoor. 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 ‘Evipo051’ described and illustrated in U.S. Plant Pat. No. 27,280 are compared to ‘Evipo115’. The claimed plant has a tepal colour after opening, on the upper surface Violet Group 84C with marginal intonations of Purple Group 77A while the comparison variety has a tepal colour after opening, upper surface Red-Purple Group 62C with central bar and margins of Purple Group N77B. The comparison variety in one season attains 50 to 60 cm in growth height. The claimed plant is very compact growing to 15 cm in height.
