Description

Botanical designation: Hydrangea macrophylla.

Cultivar denomination: ‘SCHROLL130-12-01a’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Hydrangea plant, botanically known as Hydrangea macrophylla and hereinafter referred to by the name ‘SCHROLL130-12-01a’.

The new Hydrangea plant is a product of a planned breeding program conducted by the Inventor in Aarslev, Denmark. The objective of the breeding program was to develop new container-type Hydrangea plants with strong stems, early flowering response and attractive leaf and flower coloration.

The new Hydrangea plant originated from a cross-pollination during the spring of 2012 of a proprietary selection of Hydrangea macrophylla identified as code number 11-00, not patented, as the female, or seed, parent with a proprietary selection of Hydrangea macrophylla identified as code number 27-00, not patented, as the male, or pollen, parent. The new Hydrangea plant was discovered and selected by the Inventor in February, 2014 as a flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in Aarslev, Denmark.

Asexual reproduction of the new cultivar by softwood cuttings in Aarslev, Denmark since the spring of 2015 has shown that the unique features of this new Hydrangea plant are stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

Plants of the new Hydrangea have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions 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 ‘SCHROLL130-12-01a’. These characteristics in combination distinguish ‘SCHROLL130-12-01a’ as a new and distinct Hydrangea plant:

    • 1. Upright and mounded plant habit.
    • 2. Vigorous growth habit.
    • 3. Freely branching habit and moderately strong stems.
    • 4. Dark green-colored leaves.
    • 5. Large mophead-type inflorescences with white-colored sterile flowers that are initially pale yellow green in color.
    • 6. Long flowering period.
    • 7. Good postproduction quality and longevity.

Plants of the new Hydrangea differ primarily from plants of the female selection parent in the following characteristics:

    • 1. Plants of the new Hydrangea have larger and denser inflorescences than plants of the female parent selection.
    • 2. Plants of the new Hydrangea are more freely flowering than plants of the female parent selection.
    • 3. Inflorescences of plants of the new Hydrangea are mophead types whereas inflorescences of plants of the female parent selection are lacecap types.
    • 4. Plants of the new Hydrangea and the female parent selection differ in sterile flower color as sterile flowers of plants of the new Hydrangea are white in color whereas sterile flowers of plants of the female parent selection are dark pink in color.
    • 5. Inflorescences of plants of the new Hydrangea are longer lasting than inflorescences of plants of the female parent selection.

Plants of the new Hydrangea differ primarily from plants of the male selection parent in the following characteristics:

    • 1. Plants of the new Hydrangea are more compact than and not as vigorous as plants of the male parent selection.
    • 2. Plants of the new Hydrangea are more freely flowering than plants of the male parent selection.
    • 3. Plants of the new Hydrangea and the male parent selection differ in sterile flower color as sterile flowers of plants of the new Hydrangea are white in color whereas sterile flowers of plants of the male parent selection are pink in color.
    • 4. Sterile flowers of plants of the new Hydrangea are single types whereas sterile flowers of plants of the male parent selection are double types.
    • 5. Inflorescences of plants of the new Hydrangea are longer lasting than inflorescences of plants of the male parent selection.

Plants of the new Hydrangea can be compared to plants of Hydrangea macrophylla ‘H213901’, disclosed in U.S. Plant Pat. No. 26,221. Plants of the new Hydrangea differ primarily from plants of ‘H213901’ in the following characteristics:

    • 1. Plants of the new Hydrangea are more compact than and not as vigorous as plants of ‘H213901’.
    • 2. Plants of the new Hydrangea are more freely branching than plants of ‘H213901’.
    • 3. Inflorescences of plants of the new Hydrangea are larger and flatter than inflorescences of plants of ‘H213901’.
    • 4. Sepals of sterile flowers of the new Hydrangea are not as undulate as sepals of sterile flowers of ‘H213901’.
    • 5. Plants of the new Hydrangea and ‘H213901’ differ in sterile flower color as sterile flowers of plants of the new Hydrangea are white in color whereas sterile flowers of plants of ‘H213901’ are dark red purple in color.

Plants of the new Hydrangea can be compared to plants of Hydrangea macrophylla ‘H213906’, disclosed in U.S. Plant Pat. No. 26,509. Plants of the new Hydrangea differ primarily from plants of ‘H213906’ in the following characteristics:

    • 1. Plants of the new Hydrangea have glossier leaves than plants of ‘H213906’.
    • 2. Plants of the new Hydrangea force slower than plants of ‘H213906’.
    • 3. Plants of the new Hydrangea are not as freely flowering as plants of ‘H213906’.
    • 4. Plants of the new Hydrangea and ‘H213906’ differ in sterile flower color as sterile flowers of plants of the new Hydrangea are white in color whereas sterile flowers of plants of ‘H213906’ are dark pink in color.

 DETAILED BOTANICAL DESCRIPTION

Plants used in the aforementioned photographs and in the following description were grown during the spring in 13-cm containers in a glass-covered greenhouse in Aarslev, Denmark and under cultural practices typical of commercial Hydrangea production. Plants of the new Hydrangea were pinched two times and were one year old when the photographs and description were taken. During the production of the plants, day temperatures ranged from 15° C. to 25° C. and night temperatures ranged from 10° C. to 20° C. and light levels ranged from 40 to 50 klux. Plants are typically not “blued”, that is, treated with aluminum sulfate to change the color of the inflorescences.
