Poinsettia plant named ‘LAZZPOSUGI’

Abstract

A new and distinct cultivar of Poinsettia plant named ‘LAZZPOSUGI’, characterized by its broadly upright and uniformly mounding plant habit; moderately vigorous to vigorous growth habit; freely branching habit; dark green-colored leaves; relatively early flowering; large and full inflorescences with red and light yellow bi-colored flower bracts; and excellent post-production longevity.

Description

Botanical designation: Euphorbia pulcherrima Willd.

Cultivar denomination: ‘LAZZPOSUGI’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Poinsettia plant, botanically known as Euphorbia pulcherrima Willd. and hereinafter referred to by the name ‘LAZZPOSUGI’.

The new Poinsettia plant is a product of a planned breeding program conducted by the Inventor in Sabaudia, Italy. The objective of the breeding program is to create new uniform and freely-branching Poinsettia plants with attractive flower bracts.

The new Poinsettia plant is a naturally-occurring branch mutation of Euphorbia pulcherrima Willd. ‘Superba Glitter Red & White’, not patented. The new Poinsettia plant was discovered and selected by the Inventor on a single flowering plant of ‘Superba Glitter Red & White’ in a controlled greenhouse environment in Sabaudia, Italy in December, 2015.

Asexual reproduction of the new Poinsettia plant by terminal vegetative cuttings in a controlled greenhouse environment in Sabaudia, Italy since May, 2016 has shown that the unique features of this new Poinsettia plant are stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

Plants of the new Poinsettia have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature, daylength and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘LAZZPOSUGI’. These characteristics in combination distinguish ‘LAZZPOSUGI’ as a new and distinct Poinsettia plant:

• • 1. Broadly upright and uniformly mounding plant habit.
  • 2. Moderately vigorous to vigorous growth habit.
  • 3. Freely branching habit.
  • 4. Dark green-colored leaves.
  • 5. Relatively early flowering.
  • 6. Large and full inflorescences with red and light yellow bi-colored flower bracts.
  • 7. Excellent post-production longevity.

Plants of the new Poinsettia can be compared to plants of the mutation parent, ‘Superba Glitter Red & White’. Plants of the new Poinsettia differ primarily from plants of ‘Superba Glitter Red & White’ in flower bract color as plants of the new Poinsettia have red and light yellow bi-colored flower bracts whereas plants of ‘Superba Glitter Red & White’ have pink, red and white tri-colored flower bracts.

Plants of the new Poinsettia can be compared to plants of Euphorbia pulcherrima Willd. ‘Primero Glitter’, not patented. In side-by-side comparisons, plants of the new Poinsettia differ primarily from plants of ‘Primero Glitter’ in the following characteristics:

• • 1. Plants of the new Poinsettia have a more uniform plant habit than plants of ‘Primero Glitter’.
  • 2. Plants of the new Poinsettia flower about one to two weeks earlier than plants of ‘Primero Glitter’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs illustrate the overall appearance of the new Poinsettia plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors ofthe new Poinsettia plant.

The photograph on the first sheet comprises a side perspective view of a typical flowering plant of ‘LAZZPOSUGI’ grown in a container.

The photograph on the second sheet is a close-up view of a typical inflorescence of ‘LAZZPOSUGI’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown during the autumn and winter in 13-cm containers in a glass-covered greenhouse in Merano, Italy and under cultural practices typical of commercial Poinsettia production. During the production of the plants, day temperatures ranged from 15° C. to 20° C., night temperatures ranged from 10° C. to 15° C. and light levels ranged from 40 to 55 klux. Plants were pinched one time two weeks after planting, grown under natural daylength conditions and were five months old when the photographs and the detailed description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
