Abstract

A new and distinct cultivar of Hydrangea plant named ‘FRENCH BOLERO’ is disclosed, characterized by a distinct combination of small, narrow foliage, and a flattened lacecap inflorescence composed of light pink flowers. Plants are sterile, begin flowering early and produce numerous thin stems. The new variety is a Hydrangea, normally produced as an ornamental plant for containers or gardens.

Description

Latin name of the genus and species: Hydrangea hybrid.

Variety denomination: ‘FRENCH BOLERO’.

BACKGROUND OF THE INVENTION

The new Hydrangea cultivar is a product of a planned breeding program conducted by the inventors, Claudie Lambert and Helene Bertrand, in France. The objective of the breeding program was to identify new Hydrangea varieties with unique qualities for ornamental purposes. The crossing resulting in the new variety conducted by the inventors at a research nursery in Angers, France during 2007. Selection of the new variety was made during 2010.

The seed parent is an unpatented, unnamed proprietary variety Hydrangea scandens. The pollen parent is an unpatented, unnamed proprietary variety Hydrangea hybrid.

Asexual reproduction of the new cultivar ‘FRENCH BOLERO’ by softwood cuttings was first performed during the Summer of 2017 at a commercial greenhouse in Brain sur l'Authion, France. Subsequent propagation has shown that the unique features of this cultivar are stable and reproduced true to type in two successive generations.

SUMMARY OF THE INVENTION

The cultivar ‘FRENCH BOLERO’ 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 ‘FRENCH BOLERO’. These characteristics in combination distinguish ‘FRENCH BOLERO’ as a new and distinct Hydrangea cultivar:

    • 1. Small, narrow leaves.
    • 2. Large flattened inflorescences composed of light pink flowers.
    • 3. Thin and numerous stems, easily branching.
    • 4. Early flowering at each node.
    • 5. Interspecific sterile hybrid.
PARENT COMPARISON

Plants of the new cultivar ‘FRENCH BOLERO’ are similar to plants of the seed parent in most horticultural characteristics, however, plants of the new cultivar ‘FRENCH BOLERO’ differ in the following:

    • 1. Flowers of the new variety are large and light pink, flowers of the seed parent are small and white.

Plants of the new cultivar ‘FRENCH BOLERO’ are similar to plants of the pollen parent in most horticultural characteristics, however, plants of the new cultivar ‘FRENCH BOLERO’ differ in the following:

    • 1. Inflorescence of the new variety are entirely sterile, inflorescence of the pollen parent include both sterile and fertile flowers.
    • 2. Flowers of the pollen parent are darker pink than those of the new variety.
    • 3. Stems of the new variety are thinner than stems of the pollen parent.
COMMERCIAL COMPARISON

‘FRENCH BOLERO’ can be compared to the commercial variety Hydrangea ‘Runaway Bride’, patent status unknown. These varieties are similar in most horticultural characteristics; however, ‘FRENCH BOLERO’ differs in the following:

    • 1. ‘French Bolero’ has light pink flowers, ‘Runaway Bride’ has white flowers.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photograph in FIG. 1 illustrates in full color a typical flowering plant of ‘FRENCH BOLERO’ grown in a greenhouse in France. Age of the plant photographed is approximately 1 year.

FIG. 2 illustrates a close up of the inflorescence.

The photographs were 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.
