Abstract

A new and distinct cultivar of geranium plant named ‘Fisrorose’, as described and illustrated, and particularly characterized by the combined features of intense, salmon-pink, flower color, large, cup-shaped flowers, luxuriant, medium-green foliage with strong zonation, medium to tall plant habit, and early spring flowering response.

Description

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of geranium plant, botanically known as Pelargonium zonale, and hereinafter referred to by the cultivar name ‘Fisrorose’.

‘Fisrorose’ is a product of a planned breeding program which had the objective of creating new geranium varieties with salmon-pink to deep salmon, semi-double flowers, zoned foliage, and medium-tall plant habit.

‘Fisrorose’ originated from a hybridization made by the inventor, Angelika Utecht, in a controlled breeding program in Galdar, Gran Canaria, Spain, in 1992. The female parent was a hybrid seedling, designated no. 1061-1 (unpatented), characterized by large, red, semi-double flowers, large, relatively light-green foliage with strong zonation, and vigorous growth. The male parent was the commercial variety ‘Penve’ (U.S. Plant Pat. No. 9,970), characterized by purple-pink, semi-double flowers, medium-green foliage with slight zonation, and early flowering response.

‘Fisrorose’ was selected as one flowering plant within the progency of the stated cross by the inventor, Angelika Utecht, in 1993 in a controlled environment in Galdar, Gran Canaria, Spain.

The first act of asexual reproduction of ‘Fisrorose’ was accomplished when vegetative cuttings were taken from the initial selection in autumn 1993 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 1995 in Hillscheid, Germany, and continuing thereafter, has demonstrated that the combination of characteristics as herein disclosed for ‘Fisrorose’ are firmly fixed and are retained through successive generations of asexual reproduction.

BRIEF DESCRIPTION OF THE INVENTION

The following traits have been repeatedly observed and are determined to be basic characteristics of ‘Fisrorose’, which in combination distinguish this geranium as a new and distinct cultivar:

1. Intense salmon-pink to bluish-pink flower color;

2. Large, cup-shaped, semi-double flowers in wide umbels;

3. Relatively large, medium-green foliage with strong zonation;

4. Moderately vigorous growth; and

5. Early spring flowering response.

‘Fisrorose’ has not been observed under all possible environmental conditions. The phenotype of the new cultivar may vary significantly with variations in environment such as temperature, light intensity and day length without any change in the genotype. The following observations, measurements, and comparisions describe plants grown in Hillscheid, Germany, and in Langley, British Columbia, Canada, under greenhouse conditions which approximate those generally used in commercial practice.

Of the many commercial cultivars known to the inventor, the most meaningful comparison to be made with ‘Fisrorose’, are to the cultivars ‘Fisplosive’ (U.S. Plant Pat. No. 9,388) and ‘Americana Salmon’ (U.S. Plant Pat. No. 7,933). ‘Fisrorose’ could, however, be compared with the cultivars ‘Fisplosive’ (U.S. Plant Pat. No. 9,388) or ‘Americana Salmon’ (U.S. Plant Pat. No. 7,933). In comparison to ‘Fisplosive’, ‘Fisrorose’ has a slightly less bluish, more salmon tone of flower color, medium-green foliage with stronger zonation, and a more vigorous growth habit. In comparison to ‘Americana Salmon’, ‘Fisrorose’ has a slightly more intense, pinker flower color, larger flowers, shorter peduncles, and stronger zonation of foliage.

BRIEF DESCRIPTION OF THE DRAWING

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

DETAILED BOTANICAL DESCRIPTION

The measurements were taken in Langley, British Columbia, Canada, on Jun. 15, 1999, 12 weeks after planting of rooted cuttings into 15-cm pots. The plants had not been pinched. In the following description, color references are made to The Royal Horticultural Society (R.H.S.) Colour Chart. The color values were determined indoors from plants developed in a greenhouse in May 1999 in Hillscheid, Germany.
