Description

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

Varietal denomination: ‘SYEP216’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new Poinsettia plant, botanically known as Euphorbia pulcherrima and hereinafter referred to by the variety name ‘SYEP216’.

‘SYEP216’ is a product of a planned breeding program. The new cultivar has brilliant red bracts with creamy white speckles, dark green foliage, bracts and leaves with pointed lobes, mid season flowering, and about medium sized, tight plant habit.

‘SYEP216’ originates from a naturally occurring whole plant mutation discovered in the parent variety ‘Fisson Jinglet’ (U.S. Plant Pat. No. 13,721). The mutation was discovered in the late fall of 2004, among a population of approximately 1000 single stemmed young plants of the parent variety in Hillscheid, Germany. Terminal tip cuttings of the new mutation selection were propagated and further trialed. A single plant section was again then selected in 2005 as SYEP216′. Terminal cuttings were then propagated and grown from this selection in the late fall of 2005 in Hillscheid, Germany.

Examinations continued thereafter on a larger scale, and have demonstrated that the combination of characteristics as herein disclosed for ‘SYEP216’ are firmly fixed and are retained through successive generations of asexual reproduction.

A Plant Breeder's Right for this cultivar has not been applied for. ‘SYEP216’ has not been made publicly available more than one year prior to the filing of this application. ‘SYEP216’ 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.

BRIEF DESCRIPTION OF THE DRAWING(S)

The accompanying photographic drawing shows typical flower and foliage characteristics of ‘SYEP216’ with colors being as true as possible with an illustration of this type. The photographic drawing taken in late November 2009 in Enkhuizen, Netherlands, shows the top view of an approximately 18 week old flowering plant of the new variety.

 DETAILED BOTANICAL DESCRIPTION

The measurements were taken in Hillscheid, Germany in early January 2010 on 23 week old plants that were grown on benches in a greenhouse. Culture of these plants had started in late July 2009 with planting rooted cuttings in 14 cm pots and terminal pinching of the apices 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.

BRIEF SUMMARY OF INVENTION

The following observations, measurements, and comparisons describe plants grown on benches in a greenhouse in Hillscheid, Germany. 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 plant as a new and distinct variety.
