USPP17658P2 - Poinsettia plant named ‘Fismars Creme’ - Google Patents

Abstract

A new Poinsettia plant particularly distinguished by medium size, overlapping, cream-white bracts with flat, rosette-like inflorescences, uniform deep green foliage, ovate leaves with nearly no lobes, a medium flowering response and a compact to medium size, round plant habit, is disclosed.

Description

Genus and species: Euphorbia pulcherrima (Willd. Ex Klotzsch).

Variety denomination: ‘Fismars Creme’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct cultivar of poinsettia plant, botanically known as Euphorbia pulcherrima (Willd. Ex Klotzsch) and hereinafter referred to by the cultivar name ‘Fismars Creme’. The new cultivar is the result of an induced mutation in the poinsettia plant ‘Fismars’ (U.S. Plant Pat. No. 14,977) made in the year 2003 in Ahrensburg, Germany.

In May 2003, young plants of ‘Fismars’ were irradiated in Ahrensburg, Germany. The treated plants were grown in Hillscheid, Germany, and were propagated by shoot tip cuttings. The resulting plants were screened for positive mutations and examined during the flowering period in Fall 2004. Among these plants, one plant was selected and asexually multiplied for further examination in 2004. As a result, it was concluded that this new poinsettia plant is distinguishable from any other poinsettia variety whose existence is known to the inventor.

The new cultivar was created in 2003 in Ahrensburg, Germany and has been asexually reproduced repeatedly by vegetative cuttings in Hillscheid, Germany over a two-year period. ‘Fismars Creme’ has not been observed under all possible environmental conditions. The present invention has been found to retain its distinctive characteristics through successive asexual propagations.

Plants Breeder's Rights for this cultivar were applied for in Europe on Feb. 9, 2005 and in Canada on Mar. 18, 2005.

SUMMARY OF THE INVENTION

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

• • 1. A cream-white bract color;
  • 2. A medium size, flat, rosette-like inflorescence with an overlapping arrangement of bracts;
  • 3. Uniform, deep green foliage with ovate leaves that have nearly no lobes;
  • 4. A compact to medium size, round shaped plant habit; and
  • 5. A medium flowering response.

DESCRIPTION OF PHOTOGRAPH

This new poinsettia plant is illustrated by the accompanying photographs which show overall plant habit including blooms, buds and foliage of the plant; the colors shown are as true as can be reasonably obtained by conventional photographic procedures. The photographs are of a whole plant about 18-weeks old and in full flower, grown in a greenhouse in Hillscheid, Germany, in early December of 2005.

FIG. 1 shows the overall plant habit, including blooms, buds and foliage.

FIG. 2 shows a close-up of the mature inflorescences.

DESCRIPTION OF THE NEW CULTIVAR

The following detailed description sets forth the distinctive characteristics of ‘Fismars Creme’. The data which define these characteristics were collected from asexual reproductions carried out in Hillscheid, Germany. The plant history was taken on 18-week old plants which were planted as rooted cuttings in 14-cm pots on Jul. 28, 2005 and were pinched on Aug. 12, 2005, which left 7 to 8 leaves remaining. The plants were grown in a greenhouse at a minimum temperature of 18° C. and a ventilation temperature of 24° C. The plants initiated flowers under natural short-day conditions in the Fall. No black cloth was applied to the greenhouse to simulate short-day conditions. No growth regulator was applied. 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.) (2001).

COMPARISON WITH PARENTAL AND COMMERCIAL CULTIVARS

‘Fismars Creme’ differs from the parental cultivar ‘Fismars’ (U.S. Plant Pat. No. 14,977) by having cream-white bracts and shorter leaves, while ‘Fismars’ has red bracts and longer leaves. Additionally, ‘Fismars Creme’ has an earlier flowering response and develops few to no stamens, while ‘Fismars’ has a normal number of stamens.

‘Fismars Creme’ differs from the commercial cultivar ‘Fiscor Creme’ (U.S. Plant Pat. No. 10,824), by having shorter bracts as well as leaves with few to no lobes, with branches that are more upright and a narrow plant habit compared to ‘Fiscor Creme’. Additionally, ‘Fismars Creme’ develops few to no stamens while ‘Fiscor Creme’ develops about 20 stamens per cyathium.
