USPP16964P2 - Poinsettia plant named ‘Fiscinne’ - Google Patents

Abstract

A Poinsettia cultivar particularly distinguished by its salmon-colored bracts with pink freckles, uniform dark green leaves with distinct pointed lobes, and early flowering response is disclosed.

Description

Genus and species: Euphorbia pulcherrima (Willd.).

Variety denomination: ‘Fiscinne’.

BACKGROUND OF THE NEW PLANT

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 ‘Fiscinne’. ‘Fiscinne’ is the result of an induced mutation in the variety ‘Fismille’ (U.S. Plant Pat. No. 13,660). ‘Fismille’ is characterized by large, bright red bracts, dark-green foliage, ovate shaped leaves, upright and medium to tall plant habit, and very early flowering time.

Irradiation of young plants of ‘Fismille’ was conducted in Ahrensburg, Germany on May 1998. The irradiated plants were grown in Hillscheid, Germany and were propagated by cuttings. The flowering plants derived thereof were screened for positive mutations throughout 1999 and later. One plant was selected for propagation by cuttings. The asexually propagated offspring of that plant proved to be uniform when examined in trial cultivations in the fall of 2001 and 2002, and the clone has remained stable since then.

Horticultural examination of the clone starting in 2001 and continuing thereafter has confirmed that the combination of characteristics as herein disclosed for ‘Fiscinne’ are firmly fixed and retained through successive generations of asexual reproduction.

The following traits have been repeatedly observed and are determined to be the basic characteristics of ‘Fiscinne’ which in combination distinguish this Poinsettia as a new and distinct cultivar:

• • salmon bract color; slightly freckled with pink
  • medium to large sized inflorescence, ovate bracts with weak lobes
  • uniform dark-green foliage, ovate leaves with distinct, pointed lobes
  • medium or over sized, upright plant habit
  • early flowering response

DESCRIPTION OF PHOTOGRAPH

This new Poinsettia plant is illustrated by the accompanying photograph which shows the plant's form, foliage and flowers. The colors shown are as true as can be reasonably obtained by conventional photographic procedures.

DESCRIPTION OF THE NEW CULTIVAR

‘Fiscinne’ has not been observed under all possible environmental conditions. The phenotype may vary significantly with variations in environment such as temperature, light intensity, and day-length. The following observations, measurements and comparisons describe plants grown in Hillscheid, Germany under greenhouse conditions which approximate those generally used in commercial practice.

The plants described were grown in a greenhouse in Hillscheid, Germany from the summer to the fall of 2004. Rooted cuttings were planted in 14 cm pots on Jul. 22, 2004 and were pinched on August 6, which left 7-8 leaves remaining. Initially, the minimum temperature was 18° C. Beginning October 1, the temperature was lowered to a minimum temperature of 16 to 17° C. The plants initiated flowers under natural short-day conditions in fall. No black cloth was applied to the greenhouse to simulate short-day conditions. No growth regulator was applied.

Observations and measurements were mainly taken in early to mid-December, when the plants were in full flower and about 20 weeks old. In the following description, color references are made to The Royal Horticultural Society Colour Chart (R.H.S.). The color references were determined indoors in a north light.

COMPARISON WITH KNOWN CULTIVARS

The most similar cultivars in comparison to ‘Fiscinne’ are the parental cultivar ‘Fismille’ (U.S. Plant Pat. No. 13,660), the variety ‘Fisvinci’ (U.S. Plant Pat. No. 14,107), and the cultivar ‘Fiscor Candy’ (U.S. Plant Pat. No. 11,593). In comparison to ‘Fismille’, ‘Fiscinne’ has a different bract color, is shorter in height and has leaves which show distinct lobes.

In comparison to ‘Fisvinci’, ‘Fiscinne’ has a lighter, more yellow-orange, less pink main hue of bract color and develops less distinct lobing of bracts and leaves. Additionally, ‘Fiscinne’ has a taller and more upright plant habit.

In comparison to ‘Fiscor Candy’, ‘Fiscinne’ has a much earlier flowering response, its bracts are not flat, but undulated, and its plant habit is less wide with the branches more upright-directed.
