Abstract

Description

BOTANICAL CLASSIFICATION

Pelargonium zonale.

VARIETY DENOMINATION

‘Fisvulk’.

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 ‘Fisvulk’.

‘Fisvulk’ is a product of a planned breeding program which had the objective of creating new geranium varieties with scarlet flower color, relatively compact plant habit, and generally suitable for eary sale.

‘Fisvulk’ originated from a hybridization made by the inventor Angelika Utecht in a controlled breeding program in Galdar, Gran Canaria, Spain, in 1995. The female parent was the commercial, unpatented variety ‘Fisnida’, characterized by orange-red colored, single-type flowers, large umbels, medium green, zoned foliage, and relatively vigorous growth. The male parent of ‘Fisvulk’ was the commercial, unpatented variety ‘Othello’, having orange-red, semi-double flowers, medium green foliage with strong zonation, and compact plant habit.

‘Fisvulk’ was selected as one flowering plant within the progeny of the stated cross by Angelika Utecht in 1996 in a controlled environment in Galdar, Gran Canaria, Spain. The first act of asexual reproduction of ‘Fisvulk’ was accomplished when vegetative cuttings were taken from the initial selection in the fall of 1996 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 1997 in Hillscheid, Federal Republic of Germany, and continuing thereafter, has demonstrated that the combination of characteristics as herein disclosed for ‘Fisvulk’ are firmly fixed and are retained through successive generations of asexual reproduction. The new cultivar reproduces true to type.

‘Fisvulk’ 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 ‘Fisvulk’ in combination distinguish this geranium as a new and distinct cultivar:

1. Round, orange-red, semi-double flowers;

2. Medium sized, roughly semi-spherically shaped inflorescence;

3. Relatively large, medium-green leaves with distinct zonation;

4. Medium sized, well branched and uniformly mounded 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 ‘Fisvulk’ is the patented varieties ‘Fisgrand’ (U.S. Plant Pat. No. 8,760), and the related cultivars ‘Fismerk’ (U.S. Plant Pat. No. 12,444), and ‘Fisfire’ (U.S. Plant Pat. No. 12,489).

In comparison to ‘Fisgrand’, ‘Fisvulk’ has an almost similar flower color, but shorter peduncles, and more compact, and more evenly shaped plant habit, and more flowers are developed throughout the summer.

In comparison to ‘Fismerk’, ‘Fisvulk’ has more open, cup-shaped flowers, while those of ‘Fismerk’ look double with the inner petals somewhat irregularly arranged. Furthermore, ‘Fismerk’ has fuller, more than semi-spherically shaped umbels, smaller leaves, and somewhat lower plant habit than ‘Fisvulk’.

In comparison to ‘Fisfire’, ‘Fisvulk’ has a less intense, a brighter hue of flower color, and not quite so strong zonation of foliage.

In comparison to ‘Othello’, ‘Fisvulk’ has larger umbels and a more distinct zonation of the foliage.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying photographic drawing shows typical flower and foliage characteristics of ‘Fisvulk’ with colors being as true as possible with an illustration of this type.

The drawing shows a flowering pot plant in a 14 cm container.

DETAILED BOTANICAL DESCRIPTION

In the following description color references are made to The Royal Horticultural Society Colour Chart (R.H.S.). The color values were determined indoors from flowering plants growing in a green-house in May 2001, in Hillscheid, Germany. The measurements were taken in Langley, British Columbia, Canada, in early July 2001, 18 weeks after planting of rooted cuttings. The plants were growing in 8 inch containers and had not been pinched.
