Clematis plant named ‘Cleminov 51’

Abstract

A new and distinct variety of Clematis plant is provided that is the product of a controlled breeding program. Attractive purple flowers are formed on a substantially continuous basis over an extended period of time. The growth habit is compact and bushy and the plant well resists wilting and withering. The plant can be readily propagated by the use of cuttings and can be grown to advantage to provide colorful ornamentation in the landscape and in pots.

Description

Botanical/commercial classification: Clematis hybrida/Clematis Plant.

Varietal denomination: cv. ‘Cleminov 51’.

SUMMARY OF THE INVENTION

A new and distinct Clematis plant is provided that is the product of a controlled interspecific hybridization program carried out during 1994 at Beaucouzé, France. The female parent (i.e., the seed parent) was ‘The President’ Clematis variety (non-patented in the United States), and the male parent (i.e., pollen parent) was the ‘Olgae’ variety (non-patented in the United States). A single plant of the new variety of the present invention was selected during June 2002 primarily on the basis of the attractiveness of the flowers and the extremely long flowering season.

It was found that the new Clematis variety of the present invention displays the following combination of characteristics:

• • (a) exhibits a compact and bushy growth habit,
  • (b) forms in abundance on a substantially continuous basis over an extended period of time attractive purple flowers, and
  • (c) readily can be propagated by the use of cuttings.

The new variety commonly flowers on a substantially continuous basis for approximately 4 to 5 months on average from May to September which significantly exceeds the flowering period of many other Clematis varieties. Also, the new variety has been found to well resist the wilting and withering phenomenon commonly observed with respect to many previously known climbing Clematis varieties.

The new variety of the present invention well meets the needs of the horticultural industry and is particularly well suited for providing colorful ornamentation in the landscape and in pots.

The new variety of the present invention can be readily distinguished from all other Clematis varieties of which I am aware including its parental varieties on the basis of the above-identified combination of characteristics. More specifically, ‘The President’ variety is considerably less compact in its growth habit and the duration of the blooming is considerably shorter. Also, the ‘Olgae’ variety forms smaller flowers which are displayed for a considerably shorter period of time.

The new variety of the present invention has been found at Beaucouzé, France, to readily undergo asexual propagation by the rooting of cuttings. The distinctive combination of characteristics of the new variety is reliably transmitted to subsequent generations following such propagation. Accordingly, the new variety propagates true to type via asexual reproduction.

The new variety has been named ‘Cleminov 51’.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photographs show typical four year-old plants during the summer while growing at Beaucouzé, France. The plants had been asexually reproduced by the rooting of cuttings.

FIG. 1 shows the typical compact growth habit of the new variety with the abundant presence of attractive purple flowers and foliage while growing in the landscape.

FIG. 2 shows a close view of the attractive purple flowers and foliage of the new variety while growing in a pot. The arrangement of the stamens and pistils also is shown.

DETAILED DESCRIPTION

The following description is based on the observation of five year-old plants of the new variety while growing outdoors at Beaucouzé, France during September 2004. The plants had been asexually reproduced by the rooting of cuttings. Color designations are with reference to The R.H.S. Colour Chart of The Royal Horticultural Society London, England. When employed common color terms are to be accorded their customary dictionary significance.

The disease resistance of the new cultivar during observations to date has been found to be comparable to that of Clematis plants in general with no particular disease or pest problems having been encountered during observations to date.

Plants of the ‘Cleminov 51’ variety have well withstood a temperature as low as −8° C. at Beaucouzé, France. Accordingly, considerable hardiness can be attributed to the new variety.

Plants of the new ‘Cleminov 51’ variety have not been observed under all possible environmental conditions to date. Accordingly, it is possible that the phenotype expression may vary somewhat with changes in light intensity and duration, cultural practices, and other environmental conditions.
