Description

Latin name of the genus and species: Clematis hybrid.

Variety denomination: ‘YAKU050’.

BACKGROUND OF THE INVENTION

The new cultivar is the result of a breeding program, resulting from a crossing made in 1996. The inventor is Peer Sorensen, a citizen of Denmark. The new variety was discovered as a seedling resulting from the crossing of the seed parent, Clematis hybrid ‘Maria Boisselo’, unpatented with the pollen parent Clematis hybrid ‘Nelly Moser’, unpatented. The discovery was made in 2000. Crossing and discovery was made at a commercial nursery in New Zealand.

After selecting and isolating the new cultivar, asexual reproduction of the new cultivar ‘YAKU050’ was first performed in a commercial nursery Waitara, in New Zealand, by vegetative cuttings in the Fall of 2000. The inventor maintained the original plant, and observed the clones for several years, to establish stability of the characteristics. ‘YAKU050’ has since produced multiple generations and has shown that the unique features of this cultivar are stable and reproduced true to type.

SUMMARY OF THE INVENTION

The cultivar ‘YAKU050’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, 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 ‘YAKU050.’ These characteristics in combination distinguish ‘YAKU050’ as a new and distinct Clematis cultivar:

    • 1. Single, rounded flowers
    • 2. Tepals with a raspberry pink bar in center.
    • 3. 6 to 8 tepals per flower.

PARENTAL COMPARISON

Plants of the new cultivar ‘YAKU050’ are similar to the seed parent variety in most horticultural characteristics. However, ‘YAKU050’ differs in having different colored tepals than the seed parent variety.

Plants of the new cultivar ‘YAKU050’ are similar to the pollen parent variety in most horticultural characteristics. However, ‘YAKU050’ differs in having different shaped tepals than the pollen parent variety.

COMMERCIAL COMPARISON

Plants of the new cultivar ‘YAKU050’ are most similar to the commercial variety Clematis hybrid ‘Bee's Jubilee’ unpatented. Both Clematis varieties have similar plant habits, and produce similar amounts of tepals. ‘YAKU050’ differs from ‘Bee's Jubilee’ in having a lighter flower color. Additionally, plants of ‘YAKU050’ produce tepals of a different shape than those on plants of ‘Bee's Jubilee’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photograph in FIG. 1 illustrates in full color a typical plant of ‘YAKU050’ grown outdoors in British Columbia, Canada. This plant is approximately 8 months old, grown in the ground. FIG. 2 illustrates in full color a typical flower of ‘YAKU050’.

The photographs was taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.

 DETAILED BOTANICAL DESCRIPTION
