Poinsettia plant named ‘NPCW10187’

Abstract

A new poinsettia plant named ‘NPCW10187’ particularly distinguished by its compact growth, medium sized bracts, and a brilliant bright red color, is disclosed.

Description

Genus and species: Euphorbia pulcherrima Willd. ex Klotzsch.

Variety denomination: ‘NPCW10187’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct variety of poinsettia plant, botanically known as Euphorbia pulcherrima Willd. ex Klotzsch and hereinafter referred to by the variety name ‘NPCW10187’. The new variety is the result of cross conducted between November 2004 to January 2005 in Kenya, district of Nairobi, between the female parent poinsettia plant ‘P 359’ (unpatented) and the male poinsettia plant ‘Christmas Feelings’ (U.S. Plant Pat. No. 14,618). A single plant selection was subsequently chosen for further evaluation and asexual propagation.

‘NPCW10187’ was first propagated via vegetative cuttings in Stuttgart, Germany in 2006 and has been asexually reproduced by vegetative cuttings in Stuttgart, Germany for over twelve generations. ‘NPCW10187’ has been found to retain its distinctive characteristics through successive asexual propagations via vegetative cuttings.

Plant Breeder's Rights for this variety were applied for in Canada on Dec. 22, 2009. ‘NPCW10187’ has not been sold or made publicly available more than one year prior to the filing date of this application.

SUMMARY OF THE INVENTION

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

• • 1. Compact growth habit;
  • 2. Medium-sized bracts; and
  • 3. Brilliant bright red color.

DESCRIPTION OF THE PHOTOGRAPH

This new poinsettia plant is illustrated by the accompanying; the colors shown are as true as can be reasonably obtained by conventional photographic procedures.

The photograph is of a whole plant about four-months-old and in full flower.

DESCRIPTION OF THE NEW VARIETY

The following detailed description sets forth the distinctive characteristics of ‘NPCW10187’. The data which define these characteristics were collected from asexual reproductions carried out in Stuttgart, Germany. The plant history was taken on four month-old plants grown in 13 cm pots from August to December 2009 with a minimum pinch date of 32 weeks. The plants were grown in a greenhouse covered with glass. Color readings were taken under natural light in the greenhouse. Color references are primarily to The R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.) (5^th edition 2007).
