ABSTRACT:
Latin name of the genus and species of the plant claimed:
Euphorbia pulcherrima.
Variety denomination: ‘Kamp Burgundy’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of poinsettia plant known by the cultivar name ‘Kamp Burgundy’, and botanically known as
Euphorbia pulcherrima.
‘Kamp Burgundy’ derived from a naturally occurring mutation of the variety ‘Fiscor’ (U.S. Plant Pat. No. 9,364). ‘Fiscor’ is characterized by red colored bracts, dark-green foliage, and moderately compact, and rounded plant habit.
The mutation was discovered by Katharina Zerr, the inventor, in a greenhouse in Hillscheid, Germany, in December 1998. Among a group of flowering plants a darker flowered one with purple colored bracts was found, which appeared to be completely mutated. The plant was left to develop vegetative shoots, which were cut by the inventor and used for propagation (first asexual reproduction) in the spring of 1999. The resulting plants appeared uniform, and the purple bract color was stable. This result was confirmed when the propagation and examination was repeated on a larger scale in the fall of 2000.
Horticultural examination of the plant starting in 2000 and continuing thereafter has demonstrated that the combination of characteristics as herein disclosed for ‘Kamp Burgundy’ are firmly fixed and retained through successive generations of asexual reproduction.
BRIEF SUMMARY OF THE INVENTION
The following traits have been repeatedly observed and are determined to be basic characteristics of ‘Kamp Burgundy’, which in combination distinguish this Poinsettia as a new and distinct cultivar:
1. uniform, red-purple bract color;
2. relatively compact, star-shaped, flat inflorescence;
3. intense dark-green foliage with weak lobes;
4. moderately compact, rounded plant habit; and
5. medium to moderately late flowering response.
‘Kamp Burgundy’ 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.
Of the may commercial cultivars known to the inventor, the most similar in comparison to ‘Kamp Burgundy’ are the parent cultivar ‘Fiscor’, the related cultivar ‘Fiscor Dark-Red’ (U.S. Plant Pat. No. 12,723), and the commercial cultivar ‘Purple Reign’ (unpatented).
In contrast to the red flowering cultivar ‘Fiscor’, ‘Kamp Burgundy’ has darker, purple colored bracts, somewhat smaller bracts and a slightly smaller plant habit. Due to its smaller bracts, ‘Kamp Burgundy’ is marketable about 7 days later than ‘Fiscor’.
In comparison to ‘Fiscor Dark Red’, ‘Kamp Burgundy’ has a distinctly darker tone of bract color, somewhat smaller bracts, but plant habit is of approximately equal size.
In comparison to ‘Purple Reign’, ‘Kamp Burgundy’ has a more reddish and more intense, hue of bract color, while ‘Purple Reign’ has a more bluish hue and a stronger tendency to fading. Furthermore, ‘Kamp Burgundy’ has darker green foliage, and its plant habit is distinctly more compact than that of ‘Purple Reign’.
