USPP20144P2 - Hydrangea plant named ‘Sidashe’ - Google Patents

Abstract

A new and distinct Hydrangea cultivar named ‘Sidashe’ is disclosed, characterized by pink flowers with dark pink margins and a creamy white center. The new variety is a Hydrangea, and naturally blooms from April through September.

Description

Latin name of the genus and species: Hydrangea macrophylla.

Variety denomination: ‘Sidashe’.

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 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 9773 with the male parent, an undistributed proprietary variety referred to as 9742. The crossing was made by the inventor, Daniel van der Spek in the summer of 1999. ‘Sidashe’ was selected by Daniel van der Spek in May of 2001 in Nootdorp, The Netherlands.

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

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

Plants of the new cultivar ‘Sidashe’ are similar to plants of the female parent, ‘9773’ in most horticultural characteristics, however, plants of the new cultivar ‘Sidashe’ differ from ‘9773’ in the following characteristics;

• • 1. Foliage color of ‘Sidashe’ is green whereas ‘9773’ is green with purple margins.
  • 2. ‘Sidashe’ has more flowers per inflorescence.
  • 3. ‘Sidashe’ has a wider inflorescence.

Plants of the new cultivar ‘Sidashe’ are similar to plants of the male parent, ‘9742’ in most horticultural characteristics, however, plants of the new cultivar ‘Sidashe’ differ from ‘9742’ in the following characteristics;

• • 1. Flower color of ‘Sidashe’ is pink with dark pink margins and a creamy white center whereas ‘9742’ has solid pink flowers.
  • 2. ‘Sidashe’ is a taller plant.

Plants of the new cultivar ‘Sidashe’ are similar to plants of the commercial variety ‘Paris Rapa,’ U.S. Plant Pat. No. 10,906. However, plants of the new cultivar ‘Sidashe’ differ from ‘Paris Rapa’ in the following characteristics;

• • 1. Foliage of ‘Sidashe’ is much more resistant to stress than ‘Paris Rapa’.
  • 2. ‘Sidashe’ has a wider inflorescence than ‘Paris Rapa’.
  • 3. ‘Sidashe’ flowers are darker red.
  • 4. ‘Sidashe’ plants are taller than ‘Paris Rapa’.
  • 5. ‘Sidashe’ plants produce roots faster than ‘Paris Rapa’.
