Description

Latin name of the genus and species: Hydrangea macrophylla×serrata.

Variety denomination: ‘Sandy Summer’.

BACKGROUND OF THE INVENTION

The new cultivar is a product of a planned breeding program. The intent of the breeder program was to develop Hydrangea varieties with strong stems and attractive flower colors. The new variety was discovered as seedling within the planned breeding program. This seedling is a result from the crossing of the female parent, an undistributed proprietary variety referred to as 9626 with the male parent, an undistributed proprietary variety referred to as 9658. It was selected by Daniel van der Spek in May of 2002 in Nootdorp, the Netherlands.

Asexual reproduction of the new cultivar ‘Sandy Summer’ by vegetative cuttings was first performed in Nootdorp, the Netherlands during 2002 and has shown that the unique features of this cultivar are stable and reproduced true to type on successive generations.

Asexual reproduction of the new cultivar ‘Sandy Summer’ by vegetative cuttings was performed in Nootdorp, the Netherlands and has shown that the unique features of this cultivar are stable and reproduced true to type through 6 successive generations.

SUMMARY OF THE INVENTION

The cultivar ‘Sandy Summer’ 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 ‘Sandy Summer’ These characteristics in combination distinguish ‘Sandy Summer’ as a new and distinct Hydrangea cultivar:

    • 1. Full, round mophead inflorescence.
    • 2. Unique sepal coloration, pink sepal with a thin creamy white margin.
    • 3. Dark green foliage.
    • 4. Strong plant, resisting breaking in production and post-harvest situations.
    • 5. Unique serration to sepal margins.

PARENTAL COMPARISON

Plants of the new cultivar ‘Sandy Summer’ are similar to plants of the female parent, ‘9626’ in most horticultural characteristics, however, plants of the new cultivar ‘Sandy Summer’ differ from ‘9626’ in the following characteristics;

    • 1. Flower color of ‘Sandy Summer’ is pink with a creamy white margin whereas ‘9626’ is solid light pink.
    • 2. ‘Sandy Summer’ has more flowers per inflorescence.
    • 3. ‘Sandy Summer’ has a wider inflorescence.
    • 4. ‘Sandy Summer’ is a shorter plant than ‘9626’.

Plants of the new cultivar ‘Sandy Summer’ are similar to plants of the male parent, ‘9658’ in most horticultural characteristics, however, plants of the new cultivar ‘Sandy Summer’ differ from ‘9658’ in the following characteristics;

    • 1. ‘Sandy Summer’ is a shorter plant.
    • 2. Flowers of ‘Sandy Summer’ have a creamy white margin whereas ‘9658’ has solid color flowers.

COMMERCIAL COMPARISON

Plants of the new cultivar ‘Sandy Summer’ are similar to plants of the commercial variety ‘Sidasand’, U.S. Plant Pat. No. 20,145 in most horticultural characteristics. However, plants of the new cultivar ‘Sandy Summer’ differ from ‘Sidasand’ in producing an inflorescence that is a round, mophead, compared to the flattened lacecap of ‘Sidasand’. Additionally, ‘Sandy Summer’ produces flowers colored pink on the interior, with a thin creamy white margin, whereas ‘Sidasand’ flowers are creamy white with a thin red-purple margin.

Plants of the new cultivar ‘Sandy Summer’ are similar to plants of the commercial variety ‘Sidasora’, U.S. Plant Pat. No. 20,148 in most horticultural characteristics. However, plants of the new cultivar ‘Sandy Summer’ differ from ‘Sidasora’ in producing sepals that are pink, with a thin white margin, whereas ‘Sidasora’ sepals are white at the base, and pink over the rest of the surface. Additionally, ‘Sandy Summer’ produces flowers with a distinctive serrated margin to the sepal not found in ‘Sidasora’.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph in FIG. 1 illustrates in full color a typical flower of ‘Sandy Summer’. The photograph 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.
