USPP13190P3 - Geranium plant named ‘Fistwi’ - Google Patents

Abstract

A new and distinct cultivar of geranium plant named ‘Fistwi’, as described and illustrated, and particularly characterized by the combined features of round, semi-double, bright rose colored flowers with salmon flares, large inflorescences well above the foliage, medium green foliage with relatively strong zonation, and medium to tall plant habit.

Description

BOTANICAL CLASSIFICATION

Pelargonium zonale.

VARIETY DENOMINATION

‘Fistwi’.

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 ‘Fistwi’.

‘Fistwi’ is a product of a planned breeding program which had the objective of creating new geranium varieties with deep-salmon colored semi-double flowers in combination with medium green foliage, and medium sized to moderately tall plant habit.

‘Fistwi’ 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 an unpatented hybrid seedling, no. K91-1216-3, having uniform-salmon colored, single-type flowers, medium green foliage with strong zonation, and vigorous growth. The male parent of ‘Fistwi’ was an unpatented seedling ‘I93-200-4’, which was derived by self-pollinating the cultivar ‘Robe’, similar to the cultivar ‘Sassy Dark Red’ (U.S. Plant Pat. No. 8,053), which is characterized by dark-red to purple-red, semi-double flowers, medium green foliage with weak zonation, and compact plant habit. The seedling from ‘Robe’ was characterized by dark-pink flower color, and somewhat stronger zonation than ‘Robe’.

‘Fistwi’ 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 ‘Fistwi’ 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 1998 in Hillscheid, Federal Republic of Germany, and continuing thereafter, has demonstrated that the combination of characteristics as herein disclosed for ‘Fistwi’ are firmly fixed and are retained through successive generations of asexual reproduction. The new cultivar reproduces true to type.

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

1. Rose red colored, round, cup-shaped flowers;

2. Large inflorescence and long peduncles;

3. Medium green foliage with relatively strong zonation;

4. Moderately vigorous growth, and medium to tall plant habit; and

5. Medium, mid season spring flowering response.

Of the many commercial cultivars known to the present inventor, the most similar in comparison to ‘Fistwi’ is the patented cultivar ‘Fispur’ (U.S. Plant Pat. No. 10,350). In comparison to ‘Fispur’, ‘Fistwi’ has a lighter rose red flower color, RHS 52 A, in comparison to color value between 52 A and 57 A for ‘Fispur’. Additionally, ‘Fistwi’ has distinct orange flares at the bases of upper petals, which lack with ‘Fispur’. Furthermore, ‘Fistwi’ has larger leaves with somewhat stronger zonation.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying photographic drawing shows typical flower and foliage characteristics of ‘Fistwi’ 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 plants developed in a greenhouse 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.
