Abstract

A new and distinct cultivar of geranium plant named Guitoublanc, characterized by its double-type and white flowers that have a pink center; medium-green foliage with brown zonation which forms a ring near the base of the leaf for a maximum of 5 mm; compact plant habit and good branching habit.

Description

The present invention comprises a new and distinct cultivar of geranium, botanically known as Pelargonium peltatum l'hert, and hereinafter referred to by the cultivar name Guitoublanc.
Guitoublanc is a spontaneous mutation (sport) from the variety Guicerdan that was discovered by the inventors in Saint Malo, Bretagne, France in 1986. In comparison to Guicerdan, the variety Guitoublanc is more compact and the stem of the leaf blade is thicker and a little shorter. In addition, Guicerdan has pink flowers and Guitoublanc has white flowers with a pink center.
The first act of asexual reproduction of Guitoublanc was accomplished when vegetative cuttings were taken from the initial selection in 1987 in a controlled environment in Saint Malo, France by a technician working under the supervision of the inventors. Horticultural examination of selected units initiated in 1990 has demonstrated that the combination of characteristics as herein disclosed for Guitoublanc are firmly fixed and are retained through successive generations of asexual reproduction.
Guitoublanc has not been observed under all possible environmental conditions. The phenotype may vary with variations in environment such as temperature, light intensity and daylength with a change in the genotype of the cultivar. The following observations, measurements, and comparisons describe plants grown in Saint Malo (France) under greenhouse conditions which approximate those generally used in commercial practice.
The following traits have been repeatedly observed and are determined to be basic characteristics of Guitoublanc, which in combination, distinguish this geranium as a new and distinct cultiver:
1. Double-type and white flowers with a pink center.
2. Medium-green foliage.
3. Brown (ca. RHS 200A) zonation which at maximum forms 5 mm from the base of the leaf.
4. Compact plant habit.
5. Good branching habit.
Of the many commercial cultivars known to the inventors, there is no cultivar with which Guitoublanc can be closely compared.
The accompanying photographic drawings show typical flower and foliage characteristics of Guitoublanc.
FIG. 1 is a side view of the cultivar.
FIG. 2 is a top and bottom view of an individual flower from Guitoublanc.
FIG. 3 is a top and bottom view of an individual leaf from Guitoublanc.
In the following description, color references are made to the Royal Horticultural Society (RHS) Colour Chart.
