Poinsettia plant named ‘Fisearltez’

Abstract

A new Poinsettia plant named ‘Fisearltez’ particularly distinguished by the red bracts with moderate lobing, relatively large flat, rosette-like inflorescences, dark green foliage, early flowering, and a medium sized plant habit.

Description

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

Varietal denomination: ‘Fisearltez’.

BACKGROUND OF THE NEW PLANT

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

‘Fisearltez’ is a product of a planned breeding program. The new cultivar has red bracts with moderate lobing, relatively large flat, rosette-like inflorescences, dark green foliage, early flowering, and a medium sized plant habit.

‘Fisearltez’ originates as a naturally occurring whole plant mutation discovered by the breeder in a flowering trial of the parent variety ‘Fiscor,’ U.S. Plant Pat. No. 9,364, in late 2000 in Dorsten, Germany. ‘Fisearltez’ was further examined and asexually propagated, by terminal tip cuttings, starting in the spring of 2001. As the flowering response may be influenced by many factors, the resulting plant was trialed and examined for stability through several years in the annual fall trial cultivation. The characteristics of ‘Fisearltez’ are firmly fixed and retained through successive generations of asexual reproduction.

BRIEF SUMMARY OF INVENTION

‘Fisearltez’ 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 Feb. 11, 2009 and in Germany on Dec. 22, 2008. ‘Fisearltez’ has not been made publicly available more than one year prior to the filing of this application.

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.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographic drawing shows typical flower and foliage characteristics of ‘Fisearltez’ with colors being as true as possible with an illustration of this type. The photographic drawing shows a flowering potted plant of the new variety, taken in November 2008 and shows a 19-20 week old plant.

DETAILED BOTANICAL DESCRIPTION

The measurements were taken in in Hillscheid, Germany, latitude 50° north, on Dec. 10, 2009 on about 20 week old plants that were grown on benches in a greenhouse. Cultivation of these plants had started in late July 2009 with planting rooted cuttings in 14 cm pots and pinching about 2 weeks later. The plants were grown under natural day light in the fall (no black cloth used to initiate earlier flowering) and at the moderately warm temperature of 18° C. for the bench heating.
