ABSTRACT:
BOTANICAL CLASSIFICATION
Pelargonium zonale.
VARIETY DENOMINATION
‘Fistablanc’.
BACKGROUND OF THE INVENTION
The present invention comprises a new and distinct cultivar of geranium, botanically known as
Pelargonium zonale
, and hereinafter referred to by the cultivar name ‘Fistablanc’.
‘Fistablanc’ is a product of a planned breeding program which had the objective of creating a new geranium variety with white flower color and medium sized plant habit in combination with dark-green foliage, and at least a trace of zonation.
‘Fistablanc’ originated from a hybridization made by the inventor Angelika Utecht in a controlled breeding program in Galdar, Gran Canaria, Spain, in 1996. The female parent was a commercial variety ‘Glacis’ (unpatented) which is similar to ‘North Star’ (U.S. Plant Pat. No. 9,971) having white, round semi-double flowers, floriferous habit, medium-green foliage and moderately vigorous growth. The male parent of ‘Fistablanc’ was an unpatented hybrid seedling no. K93-744-5, with white, single-type flowers, dark-green foliage with distinct zonation, and medium-sized plant habit.
‘Fistablanc’ was selected as one flowering plant within the progeny of the stated cross by Angelika Utecht in the spring of 1997 in a controlled environment in Galdar, Gran Canaria, Spain.
The first act of asexual reproduction of ‘Fistablanc’ was accomplished when vegetative cuttings were taken from the initial selection in the fall of 1997 in a controlled environment in Galdar, Gran Canaria, Spain, by, or under the supervision of Angelika Utecht. Horticultural examination of plants grown from cuttings of the plant initiated in May 1998 in Hillscheid, Federal Republic of Germany, and continuing thereafter, has demonstrated that the combination of characteristics as herein disclosed for ‘Fistablanc’ are firmly fixed and are retained through successive generations of asexual reproduction. The new cultivar reproduces true to type.
‘Fistablanc’ 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, and in Langley, British Columbia, Canada, under greenhouse conditions which approximate those generally used in commercial practice.
BRIEF DESCRIPTION OF THE INVENTION
The following traits have been repeatedly observed and are determined to be basic characteristics of ‘Fistablanc’ which in combination distinguish this geranium as a new and distinct cultivar:
1. Large, white, semi-double flowers;
2. Semi-spherically shaped umbels, well above the foliage;
3. Dark-green foliage with weak zonation on young leaves;
4. Medium sized, round and uniform plant habit; and
5. Early to medium spring flowering response.
Of the many commercial cultivars known to the present inventor, the most similar in comparison to ‘Fistablanc’ are the patented varieties ‘Floscala’ (U.S. Plant Pat. No. 9,796) and the female parent ‘Glacis’.
In comparison to ‘Floscala’, ‘Fistablanc’ has larger and differently shaped flowers, rounder and slightly more compact plant habit, inflorescences borne higher above the foliage, and slightly more compact plant habit. Flowers of ‘Fistablanc’ tend not to develop a pink hue.
In comparison to ‘Glacis’, ‘Fistablanc’ has more zygomorphic, rather than round flowers and dark-green foliage.
