Geranium plant named ‘Fisaqua’

Abstract

A new and distinct cultivar of geranium plant named ‘Fisaqua’, particularly characterized by the combined features of light pink to light rose colored, cup-shaped flowers, medium green foliage with weak zonation, and medium over sized plant habit.

Description

Genus and species of the plant claimed: Hybrid of Pelargonium zonale L'Héritier.

Variety denomination: ‘Fisaqua’.

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 ‘Fisaqua’.

‘Fisaqua’ is a product of a planned breeding program which had the objective of creating new zonal geranium cultivars with light pink flower color, with markings or without, deep green foliage, and medium to vigorous growth habit.

‘Fisaqua’ originated from a hybridization made by the inventor, Angelika Utecht, in a controlled breeding program in Hillscheid, Germany, in 1996. The female parent was the patented variety ‘Fisbravo’ (U.S. Plant Pat. No. 9,765), having light bluish-pink flowers with distinct red markings, dark green foliage and fairly compact plant habit. The male parent of ‘Fisaqua’ was the unpatented variety ‘Gomera’, characterized by bluish-pink flowers with red markings on petals, medium green foliage with weak zonation, and medium sized plant habit.

‘Fisaqua’ was selected as one flowering plant within the progeny of the stated cross by Angelika Utecht in 1997 in a controlled environment in Moncarapacho, Portugal.

The first act of asexual reproduction of ‘Fisaqua’ was accomplished when vegetative cuttings were taken from the initial selection in the fall of 1997 in a controlled environment in Moncarapacho, Portugal, 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 ‘Fisaqua’ are firmly fixed and are retained through successive generations of asexual reproduction.

‘Fisaqua’ 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.

BRIEF SUMMARY OF THE INVENTION

The following observations, measurements, and comparisons describe plants grown in Hillscheid, Germany, 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 ‘Fisaqua’ in combination distinguish this geranium as a new and distinct cultivar:

1. Light pink, rose-edged, open, semi-double flowers;

2. Big, round inflorescences, on long peduncles;

3. Medium green foliage with weak zonation;

4. Medium growth, low, rounded plant habit, and

5. Medium to somewhat late spring flowering response.

Of the many commercial cultivars known to the present inventor, the most similar in comparison to ‘Fisaqua’ is the unpatented, commercial variety ‘Goesta’, the parental variety ‘Gomera’, and ‘Designer Light Pink’ (U.S. Plant Pat. No. 8,552).

In comparison to ‘Goesta’, ‘Fisaqua’ has a similar flower color, but somewhat deeper green leaf color, slightly deeper zonation, and somewhat taller plant habit. In comparison to ‘Gomera’, ‘Fisaqua’ has a lighter main flower color, and petals lack reddish or deep pink macules. In comparison to ‘Designer Light Pink’, ‘Fisaqua’ has a somewhat deeper and more variable pink main flower color, while the main flower color of ‘Designer Light Pink’ is a uniform, light-pink. Furthermore, the foliage of ‘Fisaqua’ appears somewhat deeper green, and plant habit is not quite as tall as that of ‘Designer Light Pink’.

BRIEF DESCRIPTION OF THE DRAWING

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

DETAILED BOTANICAL DESCRIPTION

The measurements were taken in Hillscheid, Germany, in mid May, 11 weeks after planting of rooted cuttings. The plants were growing in 14 cm pots, they had not been pinched.

In the following description color references are made to The Royal Horticultural Society Color Chart. The color values were determined indoors from plants growing in a green-house in May, 2003, in Hillscheid, Germany.
