Abstract

A new poinsettia plant particularly distinguished by long bracts, high vigor and a slim habit, is disclosed.

Description

Genus and species: Euphorbia pulcherrima Willd. ex Klotzsch.

Variety denomination: ‘NPCW12198’.

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 ‘NPCW12198’. The new variety is the result of cross conducted in November 2004 in Kenya, district of Nairobi, between the female parent poinsettia plant ‘KLEW01066’ (U.S. Plant Pat. No. 13,621) and an unnamed male poinsettia plant. A single plant selection was subsequently chosen for further evaluation and asexual propagation.

‘NPCW12198’ was first propagated via vegetative cuttings in Stuttgart, Germany in October 2005 and has been asexually reproduced by vegetative cuttings in Stuttgart, Germany for over 12 generations. ‘NPCW12198’ has been found to retain its distinctive characteristics through successive asexual propagations via vegetative cuttings.

‘NPCW12198’ 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. Long Bracts;
- 2. Slim plant habit; and
- 3. Highly vigorous growth.

DESCRIPTION OF THE PHOTOGRAPH

This new poinsettia plant is illustrated by the accompanying photograph; 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 ‘NPCW12198’. 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 centimeter pots from August 2011 to December 2011 with a pinch date at week 31. 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^thedition 2007).
