Abstract

A new poinsettia plant particularly distinguished by having reddish-pink bracts and a triangular plant form and upright habit, is disclosed.

Description

Genus and species: Euphorbia pulcherrima.

Variety denomination: ‘NPCW19287’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct variety of poinsettia, botanically known as Euphorbia pulcherrima and hereinafter referred to by the variety name ‘NPCW19287’. ‘NPCW19287’ was derived from a population of irradiated plants, using Gamma-Rays 20 Gy, of the variety ‘NPCW14233’ (U.S. Plant Pat. No. 27,228) in November 2014.

In February 2015, ‘NPCW19287’ was first asexually propagated by vegetative apical cuttings in Stuttgart, Germany. ‘NPCW19287’ was found to reproduce true to type in successive generations of asexual propagation via vegetative apical cuttings in Stuttgart, Germany.

SUMMARY

The following are the most outstanding and distinguishing characteristics of this new variety when grown under normal horticultural practices in Stuttgart, Germany.

- 1. Reddish-pink bracts; and
- 2. A plant having a triangular plant form and upright habit.

DESCRIPTION OF THE PHOTOGRAPH

This new poinsettia plant is illustrated by the accompanying photograph which shows an overall view of the whole plant. The photograph is of a plant approximately 12-weeks-old grown indoors in Stuttgart, Germany in December 2016. The colors shown are as true as can be reasonably obtained by conventional photographic procedures.

DESCRIPTION OF THE NEW VARIETY

The following detailed descriptions set forth the distinctive characteristics of ‘NPCW19287’. The data which define these characteristics were collected from asexual reproductions carried out in Stuttgart, Germany. Data was collected on plants that were 19-weeks from potting in a glass greenhouse under normal horticultural practices in Stuttgart, Germany. Color references are to The R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.), 5^thedition (2007) unless where otherwise stated.

COMPARISON WITH PARENTAL LINE AND COMMERCIAL VARIETY

When ‘NPCW19287’ is compared to its parental line, the following differences are noted in Table 1.

TABLE 1

	Characteristic	‘NPCW19287’	‘NPCW14233’

	Leaf length	6.0 cm to 11.0 cm	8.0 cm to 13.0 cm
	Leaf width	3.0 cm to 7.0 cm	5.0 cm to 8.0 cm

When ‘NPCW19287’ is compared with the commercial variety ‘Monet Early’ (patent status unknown), ‘NPCW19287’ flowers one week later than ‘Monet Early’ and has a smaller bract size than ‘Monet Early’.
