USPP26349P3 - Poinsettia plant named ‘NPCW13211’ - Google Patents

Abstract

A new poinsettia plant particularly distinguished by having white colored bracts, medium earliness, a small, thin stem diameter, and small cyathia, is disclosed.

Description

Genus and species: Euphorbia pulcherrima.

Variety denomination:

‘NPCW13211’.

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 ‘NPCW13211’. ‘NPCW13211’ was derived as a selection of a single, white plant among a population derived from irradiated cuttings of the poinsettia CHRISTMAS FEELINGS™ ‘Marble’ (unpatented), having white bracts with pink centers.

In November 2010, a single white plant was selected in Stuttgart, Germany from irradiated lines of poinsettia CHRISTMAS FEELINGS™ ‘Marble’. In February 2011, ‘NPCW13211’ was first asexually propagated by vegetative cuttings. ‘NPCW13211’ was found to reproduce true to type in successive generations of asexual propagation via vegetative cuttings in Stuttgart, Germany.

CROSS REFERENCE TO RELATED APPLICATIONS

Plant Breeder's Rights for ‘NPCW13211’ were applied for in Europe on Dec. 9, 2013 (Application No. 2013/3122, Grant No. 41461), however an application number has not been assigned. ‘NPCW13211’ has not been made publicly available or sold more than one year prior to the filing date of this application.

SUMMARY

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

• • 1. White colored bracts;
  • 2. Medium earliness;
  • 3. Small, thinner stem diameter; and
  • 4. Small cyathia.

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 in 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 ‘NPCW13211’. 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).
