USPP15513P3 - Geranium plant named ‘Fisrodark’ - Google Patents

Abstract

A new and distinct cultivar of geranium plant named ‘Fisrodark’, particularly characterized by the combined features of deep red, semi-double flowers, medium spring flowering response, and floriferous throughout the summer, medium-green foliage with weak zonation, relatively large leaves, vigorous growth and tall, wide plant habit.

Description

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

Variety denomination: ‘Fisrodark’.

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 ‘Fisrodark’.

‘Fisrodark’ is a product of a planned breeding program which had the objective of creating new zonal geranium cultivars with cultivars with semi-double flowers, relatively vigorous, but well-branched growth habit, good outdoor performance, and in various flower colors.

‘Fisrodark’ was originated from a hybridization made by the inventor, Angelika Utecht, in a controlled breeding program in Hillscheid, Germany, in 1998.

The female parent was the patented variety ‘Americana Dark Red’ (U.S. Plant Pat. No. 9,307), having deep-red semi-double flowers, medium green foliage, and vigorous growth. The male parent of ‘Fisrodark’ was the variety ‘Fisfire’ (U.S. Plant Pat. No. 12,489), and characterized by scarlet, semi-double flowers, leaves with strong zonation, and about medium sized plant habit.

‘Fisrodark’ was selected as one flowering plant within the progeny of the stated cross by Angelika Utecht in 1999 in a controlled environment in Moncarapacho, Portugal.

The first act of asexual reproduction of ‘Fisrodark’ was accomplished when vegetative cuttings were taken from the initial selection in the fall of 1999 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 2000 in Hillscheid, Federal Republic of Germany, and continuing thereafter, has demonstrated that the combination of characteristics as herein disclosed for ‘Fisrodark’ are firmly fixed and are retained through successive generations of asexual reproduction. ‘Fisrodark’ 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 ‘Fisrodark’ in combination distinguish this geranium as a new and distinct cultivar:

• • 1. Deep red, semi-double, round flowers;
  • 2. Numerous, medium-sized to large inflorescences, thin peduncles;
  • 3. Medium-green foliage with weak zonation;
  • 4. Vigorous growth, tall plant and well-branched plant habit; and
  • 5. About mid season spring flowering response.

Of the many commercial cultivars known to the present inventor, the most similar in comparison to ‘Fisrodark’ is the variety ‘Fip 553’ (U.S. Plant Pat. No. 13,961), and the parental variety ‘Americana Dark Red’. In comparison to ‘Fip 533’, ‘Fisrodark’ has even deeper red flower color, without a trace of orange-red. Its flower-heads are not quite as big, peduncles are thinner, but it is more floriferous than ‘Fip 553’. Additionally, leaves of ‘Fisrodark’ show somewhat less distinct zonation than the foliage of ‘Fip 553’.

In comparison to ‘Americana Dark Red’, flowers of ‘Fisrodark’ are a true deep red, they lack the slightly bluish overtone of lower petals. Furthermore, ‘Fisrodark’ has somewhat deeper green foliage with stronger zonation, while leaves of ‘Americana Dark Red’ develop no or only very slight zonation.

BRIEF DESCRIPTION OF THE DRAWING

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

DETAILED BOTANICAL DESCRIPTION

The measurements were taken in Hillscheid, Germany, in mid May 2003, 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.
