Latin name of the genus and species of the plant claimed: Euphorbia pulcherrima.

Varietal denomination: ‘EURZ0002’.


The present invention comprises a new Poinsettia, botanically known as Euphorbia pulcherrima, and hereinafter referred to by the variety name ‘EURZ0002’.

‘EURZ0002’ is a product of a planned breeding program. The new cultivar has cream-white bracts color, relatively large inflorescences with the bracts a little upright directed, early flowering response, dark green foliage, ovate leaves, and medium to strong vigour with good branching.

‘EURZ0002’ originates from an induced mutation and was selected in Enkhuizen, Netherlands among greenhouse plants of the parent variety.

The parent was the commercial plant designated ‘SYEP22432’, U.S. Plant Pat. No. 22,035, also known as ‘Titan Red’, with bright red bract color, early flowering response, dark green leaves, upright and a little more vigorously growing than ‘EURZ0002’.

Young plants of the parent variety had been exposed to x-ray radiation in Enkhuizen, Netherlands. The treated plants were then grown out in a greenhouse Enkhuizen, Netherlands.

During the flowering season from November to December 2011, ‘EURZ0002’ was discovered and selected as a single mutated plant. The first asexual propagation was made a few months later, by taking shoot tip cuttings from the mutated plant. The rooted cuttings were grown out and used for the first flowering trial in Enkhuizen, Netherlands in the fall of 2012.

Since then, the clone has been repeatedly asexually reproduced by cuttings in Enkhuizen, Netherlands and found to be true to type, uniform and stable for the new characteristic.


Horticultural examination of plants grown from cuttings of the plant initiated in the summer of 2012, and continuing thereafter, has demonstrated that the combination of characteristics as herein disclosed for ‘EURZ0002’ are firmly fixed and are retained through successive generations of asexual reproduction.

‘EURZ0002’ has not been observed under all possible environmental conditions. The phenotype may vary significantly with variations in environment such as temperature, light intensity and day length.

Plant Breeder's Rights for this cultivar were applied for in Canada on Jul. 2, 2014 No. 14-8382; and in the European Union (CPVO) on Feb. 2, 2015, No. 2015/0272.

The following traits have been repeatedly observed and are determined to be basic characteristics of the new variety. The combination of these characteristics distinguishes this Poinsettia as a new and distinct variety.


The accompanying photographic drawing shows typical flower and foliage characteristics of ‘EURZ0002’ with colors being as true as possible with an illustration of this type. The photographic drawings show flowering potted plants of the new variety. FIG. 1 is a close view flower bracts, and FIG. 2, taken shows a small flowering plant.


The measurements were taken in Hauwert, Netherlands in mid-November 2014 on about 20 week old plants growing in a greenhouse. Cultivation of these plants had started in late July 2014 with planting of rooted cuttings into 12 cm pots and terminal pinching about 2 weeks later. The plants were grown under natural day light in the fall (no black cloth to initiate earlier flowering) and at the moderately warm temperature of 18° C. for the bench heating.

The aforementioned photographs were both taken during the flowering season in mid-December 2012 in a greenhouse in Enkhuizen, Netherlands. The plants were about 20 weeks old and grown in 12 cm pots.
