Description

Latin name of the genus and species: Hydrangea macrophylla.

Variety denomination: ‘Sidasand’.

BACKGROUND OF THE INVENTION

The new cultivar is a product of a planned breeding program. The intent of this breeding program is to produce stronger pot plant varieties with 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 9659. The crossing was made by the inventor, Daniel van der Spek in the summer of 1999. ‘Sidasand’ was selected as a single plant by Daniel van der Spek in May of 2001 in Nootdorp, The Netherlands.

Asexual reproduction of the new cultivar ‘Sidasand’ 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 ‘Sidasand’ 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 ‘Sidasand’. These characteristics in combination distinguish ‘Sidasand’ as a new and distinct Hydrangea cultivar:

    • 1. Flattened inflorescence;
    • 2. Unique petal coloration of white with purple margins;
    • 3. Dark green foliage;
    • 4. Strong plant, resisting breaking in production and post-harvest situations.

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

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

Plants of the new cultivar ‘Sidasand’ are similar to plants of the male parent, ‘9659’ in most horticultural characteristics, however, plants of the new cultivar ‘Sidasand’ differ from ‘9659’ in the following characteristics;

    • 1. Foliage color of ‘Sidasand’ is darker than ‘9659.’
    • 2. ‘Sidasand’ is a shorter plant.
    • 3. Flowers of ‘Sidasand’ have a distinctive darker margin whereas ‘9659’ has solid color flowers.

Plants of the new cultivar ‘Sidasand’ are similar to plants of the commercial variety ‘Snow,’ distributed and unpatented in the United States. However, plants of the new cultivar ‘Sidasand’ differ from ‘Snow’ in the following characteristics;

    • 1. Foliage of ‘Sidasand’ is much more resistant to stress than ‘Snow.’
    • 2. ‘Sidasand’ flowers have a distinctive red/purple margin whereas flowers of ‘Snow’ are solid white.
    • 4. ‘Sidasand’ plants produce roots faster than ‘Snow.’

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph in FIG. 1 illustrates in full color a typical blooming plant of ‘Sidasand’ grown in a greenhouse. 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.

 DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart except where general terms of ordinary dictionary significance are used. The following observations and measurements describe ‘Sidasand’ plants grown in a greenhouse in Brielle, The Netherlands from October 2005 to October 2006. The growing temperature ranged from 16° C. to 17° C. at night to 18° C. to 20° C. during the day. The pH of the growing medium was between 5.0 and 5.5. ‘Sidasand’ has not been tested for the effect of Aluminum on stem, leaf and flower colors. Measurements and numerical values represent averages of typical flowering types.
