Abstract

A new and distinct cultivar of Clematis plant named ‘Prinsesse Alexandra’, characterized by its upright growth habit; freely branching habit; freely flowering habit; and large single and semi-double flowers that are pink in color.

Description

BOTANICAL CLASSIFICATION/CULTIVAR DESIGNATION
Clematis L. cultivar Prinsesse Alexandra.
BACKGROUND OF THE INVENTION
The present Invention relates to a new and distinct cultivar of Clematis plant, botanically known as Clematis L., and hereinafter referred to by the name ‘Prinsesse Alexandra’.
The new cultivar originated from a random cross-pollination of two unidentified selections of Clematis L., not patented, in Ronde, Denmark. The new cultivar was discovered and selected by the Inventor as a flowering plant within the progeny from this cross-pollination in a controlled environment in Ronde, Denmark, in 1998.
Asexual reproduction of the new cultivar by cuttings taken in Ronde, Denmark, since 1999, has shown that the unique features of this new Clematis are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
Plants of the cultivar Prinsesse Alexandra have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and light intensity without, however, any variance in genotype.
The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Prinsesse Alexandra’. These characteristics in combination distinguish ‘Prinsesse Alexandra’ as a new and distinct cultivar of Clematis:
1. Upright growth habit.
2. Freely branching habit.
3. Freely flowering habit.
4. Large single and semi-double flowers that are pink in color.
Plants of the new Clematis differ primarily from plants of the unidentified parent selections primarily in flower form and flower color.
Plants of the new Clematis can be compared to plants of the Clematis L. cultivar Nelly Moser, not patented. In side-by-side comparisons conducted in Ronde, Denmark, plants of the new Clematis differed from of the cultivar Nelly Moser in the following characteristics:
1. Plants of the new Clematis had single and double flowers whereas plants of the cultivar Nelly Moser had single flowers.
2. Plants of the new Clematis had larger flowers than plants of the cultivar Nelly Moser.
3. Single flowers of plants of the new Clematis had yellow-colored centers whereas flowers of plants of the cultivar Nelly Moser had white-colored centers.
BRIEF DESCRIPTION OF THE PHOTOGRAPH
The accompanying colored photograph illustrates the overall appearance of the new cultivar, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Clematis. The photograph comprises a side perspective view of typical flowering plants of ‘Prinsesse Alexandra’.
DETAILED BOTANICAL DESCRIPTION
In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used. Plants used for the photograph and the following description were about two years old and were grown in containers in an outdoor nursery in Ronde, Denmark. The following measurements and values represent averages taken from a group of typical flowering plants during the late summer.
