Poinsettia plant named ‘NPCW14205’

Abstract

A new poinsettia plant particularly distinguished by having dark red, elongated bracts, dark green leaves, very high vigor, nine week response time, moderate cyathia quantity, and strong stems, is disclosed.

Description

Genus and species: Euphorbia pulcherrima.

Variety denomination: ‘NPCW14205’.

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 ‘NPCW14205’. ‘NPCW14205’ is a selection from a cross-pollination of the proprietary female Euphorbia line ‘EP-2005-0103’ (unpatented) and the proprietary male Euphorbia line ‘EP-2005-0028’ (unpatented).

In November/December of 2007 the proprietary female Euphorbia line ‘EP-2005-0103’ and the proprietary male Euphorbia line ‘EP-2005-0028’ were cross pollinated in Nairobi, Kenya and seeds were obtained. The seeds were sown and plants were grown for evaluation. A plant line was selected in November 2008 in Stuttgart, Germany and named ‘NPCW14205’. In May 2009, ‘NPCW14205’ was first vegetatively propagated by vegetative cuttings. ‘NPCW14205’ was found to reproduce true to type in successive generations of asexual propagation via 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. Dark red, elongated bracts;
  • 2. Dark green leaves;
  • 3. Very high vigor;
  • 4. Nine week response time;
  • 5. Moderate cyathia quantity; and
  • 6. Strong stems.

DESCRIPTION OF THE PHOTOGRAPH

This new poinsettia plant is illustrated by the accompanying photograph which shows an overall view of the plant. The photograph is of a plant approximately four months old grown indoors Stuttgart, Germany in December 2010. 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 ‘NPCW14205’. The data which define these characteristics were collected from asexual reproductions carried out in Stuttgart, Germany. Data was collected on four month old plants grown indoors in Stuttgart, Germany under greenhouse conditions in the fall of 2013. Color references are to The R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.), 5^th edition (2007).
