USPP21583P3 - Clematis plant named ‘Evipo016’ - Google Patents

Abstract

A new Clematis plant with a compact growth habit and profuse red flowers with a red and white flower centre and continuous summer flowering. The variety successfully propagates from softwood cuttings and is suitable for cultivation in commercial nursery and glasshouse 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: ‘Evipo016’.

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 Clematis ‘Bees Jubilee’, and the male pollen parent, an un-named seedling.

The two parents were crossed during the summer of 1997 and the resulting seeds were planted the following winter in a controlled environment in Guernsey, Channel Islands, United Kingdom. The new variety named ‘Evipo016’ originated as a single seedling from the stated cross.

The new clematis plant may be distinguished from its female seed parent primarily by flower color. ‘Bees Jubilee’ has pink flowers, while ‘Evipo016’ has red flowers.

The new clematis plant may be distinguished from its male pollen parent by the following combination of characteristics:

• • 1. The pollen parent is less compact in height than ‘Evipo016’.
  • 2. The pollent parent has pink flowers, while ‘Evipo016’ has red flowers.

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

• • 1. Uniform and profuse red flowers;
  • 2. Vigorous and compact growth, making the variety suitable for medium container culture
  • 3. Flowers on season old and current seasons growth.
  • 4. Consistent flower production on commercial scale.

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.

‘Evipo016’ was selected by Mogens N. Olesen and Raymond J. Evison in their clematis development program in the Channel Islands, United Kingdom in July 1998. Asexual reproduction of ‘Evipo016’ 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 1998. This initial and subsequent asexual propagations have demonstrated that the characteristics of ‘Evipo016’ are true to type and are transmitted from one generation to the next.

DETAILED DESCRIPTION OF THE VARIETY

The following is a detailed description of ‘Evipo016’, as observed in its growth throughout the flowering period in glasshouses in the Channel Islands, United Kingdom. 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 ‘Evipo002’ described and illustrated in U.S. Plant Pat. No. 15,797 issued June 14, 2005 are compared to ‘Evipo016’ in Chart 1.
