Description

Latin name of the genus and species: Hydrangea macrophylla.

Variety denomination: ‘Sidaseli’.

BACKGROUND OF THE INVENTION

The new cultivar is a product of a planned breeding program. The intent of this breeding program was stronger pot plant varieties with attractive flower colors. The new variety was discovered as a 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 9723 with the male parent, an undistributed proprietary variety referred to as 9654. ‘Sidaseli’ was selected as a single plant by Daniel van der Spek in May of 1999 in Nootdorp, the Netherlands.

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

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

Plants of the new cultivar ‘Sidaseli’ are similar to plants of the female parent, ‘9723’ in most horticultural characteristics, however, plants of the new cultivar ‘Sidaseli’ has significantly different flower coloration. Flowers of the new cultivar are distinctively red/purple with a white center, while the female parent has solid red flower coloration and less flowers per inflorescence. ‘Sidaseli’ differs from the male parent ‘9654’ in foliage color. Foliage of the new cultivar is 139A, much darker than the male parent. Additionally, the new variety has smaller leaves as well as more leaves per lateral branch.

Plants of the new cultivar ‘Sidaseli’ are similar to plants of the commercial variety ‘Twilight,’ unpatented in the United States in inflorescence type and color. However, plants of the new cultivar ‘Sidaseli’ differ in the following characteristics;

    • 1. Foliage of ‘Sidaseli’ is much darker than ‘Twilight’
    • 2. ‘Sidaseli’ produces more lateral branches than ‘Twilight.’
    • 3. ‘Sidaseli’ flowers earlier than ‘Twilight’ under natural conditions.
    • 4. ‘Sidaseli’ flowers earlier than ‘Twilight’ under production greenhouse conditions.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph in FIG. 1 illustrates in full color a typical blooming plant of ‘Sidaseli’ 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 ‘Sidaseli’ 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° during the day. The pH of the growing medium was between 5.0 and 5.5. ‘Sideseli’ has has been inserted in its place not been tested for the effect of Aluminum on stem, leaf and flower colors. Measurements and numerical values represent averages of typical flowering types.
