Abstract
A new and distinct Poinsettia plant named ‘Fiswhite Silver’, characterized as having creamy-white bract color; medium to large size inflorescences with ovate bracts; light green to grayish green foliage with narrow, irregular white margins; just under medium sized, tight and bushy plant habit; and medium (mid season) flowering response.
Description
Latin name of the genus and species of the plant claimed: Euphorbia pulcherrima Willd. ex Klotzsch.
Variety denomination: Fiswhite Silver.
The present invention relates to a new and distinct cultivar of poinsettia plant known by the cultivar name ‘Fiswhite Silver’, and botanically known as Euphorbia pulcherrima.
‘Fiswhite Silver’ was derived from a naturally occurring mutation in the variety ‘Fispue White’ (U.S. Plant patent application Ser. No. 08/099,764). The mutation was discovered by the inventor, Katharina Zerr, in a greenhouse in Hillscheid, Germany, in the winter of 1999/2000. Among a group of flowering plants of the parent variety one plant partly developing variegated foliage was found. These mutated branches were used for asexual propagation in the spring of 2000. The resulting plants appeared uniform, and the variegation of the leaves was stable. This result was confirmed when the propagation and examination was repeated on a larger scale in the fall of 2001.
Horticultural examination of the clone starting in 2000 and continuing thereafter has demonstrated that the combination of characteristics as herein disclosed for ‘Fiswhite Silver’ are firmly fixed and retained through successive generations of asexual reproduction.
The following traits have been repeatedly observed and are determined to be basic characteristics of ‘Fiswhite Silver’, which in combination distinguish this Poinsettia as a new and distinct cultivar:
1. Creamy-white bract color;
2. medium to large size inflorescences with ovate bracts;
3. light green to grayish green foliage with narrow, irregular white margins;
4. just under medium sized, tight and bushy plant habit; and
5. medium (mid season) flowering response.
‘Fiswhite Silver’ has not been observed under all possible environmental conditions. The phenotype may vary significantly with variations in environment such as temperature, light intensity, and daylength. The following observations, measurements and comparisons describe plants grown in Hillscheid, Germany, under greenhouse conditions which approximate those generally used in commercial practice.
Of the may commercial cultivars known to the inventor, the most similar in comparison to ‘Fiswhite Silver’ is the parent cultivar ‘Fispue White’, and the related variety ‘Fispue Silver’, (U.S. Plant patent application Ser. No. 09/099,768, later withdrawn).
‘Fispue White’ is characterized by white colored bracts, medium-green foliage almost without lobes, upright, moderately tall plant habit and early beginning of flowering. In contrast to the uniform, medium-green leaves of ‘Fispue White’, ‘Fiswhite Silver’ has variegated foliage of lighter green color and with narrow white margins. ‘Fiswhite Silver’ has an intermediate plant size and growth habit between ‘Fispue White’ and ‘Fispue Silver’.
In comparison to ‘Fispue Silver’, ‘Fiswhite Silver’ has a somewhat taller plant habit and wider bracts and leaves. Its variegated foliage is more regularly/uniform shaped, and deformations of edges occur to a distinctly lesser degree than with leaves of ‘Fispue Silver’. Furthermore, ‘Fiswhite Silver’ is marketable about one week earlier than ‘Fispue Silver’, which is partly due to its larger bracts.
The accompanying color photographic drawing shows typical inflorescence and foliage of ‘Fiswhite Silver’, with colors being as true as possible with illustrations of this type. The photograph shows a mature potted plant.
The plants described were grown in a greenhouse in Hillscheid, Germany, in the fall of 2002. Rooted cuttings were planted into 14 cm pots on July 25, and were pinched on August 8, leaving 7-8 leaves. Initially, the temperature was between a minimum of 19° C. and 24.5° C. maximum (ventilation temperature), and lower beginning October 1, minimum 16° C. to 23° C. The plants initiated flowers under short-day conditions under natural short-day conditions in fall, no black cloth was applied.
Observations and measurements were mainly taken in mid December, when the plants were in full flower and about 20 weeks old.
