USPP12444P2 - Geranium plant named ‘Fismerk’ - Google Patents

Abstract

A new and distinct cultivar of geranium plant named ‘Fismerk’, as described and illustrated, and particularly characterized by the combined features of intense orange-red, semi-double flowers, semi-spherical inflorescence, early and rich flowering, and relatively compact growth habit in the beginning, therefore well suited for early cultivation.

Description

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 ‘Fismerk’.

‘Fismerk’ is a product of a planned breeding program which had the objective of creating new geranium varieties with scarlet flower color, compact habit, and in general suitable for early sale. ‘Fismerk’ 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 a hybrid seedling, no. 990-1 (unpatented), derived from a cross between ‘Fisnida’ (unpatented) and ‘Volcano’ (U.S. Plant Pat. No. 5,940). Both varieties have orange-red flowers, the former single-type flowers, the latter semi-double ones. The hybrid seedling was charaterized by red, single-type flowers, large inflorescences, and medium green, zoned foliage. The male parent of ‘Fismerk’ was the hybrid seedling no. 1383-2 (unpatented), which was characterized by orange-red, semi-double flowers, foliage with distinct zonation, and medium tall plant habit.

‘Fismerk’ 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 ‘Fismerk’ 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 1999 in Hillscheid, Federal Republic of Germany, and continuing thereafter, has demonstrated that the combination of characteristics as herein disclosed for ‘Fismerk’ are firmly fixed and are retained through successive generations of asexual reproduction.

‘Fismerk’ 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 DESCRIPTION OF THE INVENTION

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.

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

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

2. Large, semi-spherical umbels;

3. Medium-green foliage with distinct zonation;

4. Compact to medium plant habit during cultivation in green-house, grows outdoors with medium vigor;

5. Early and rich flowering as a pot plant; and

6. Suitable for early sale, due to the early flowering and requiring relatively little space during cultivation.

Of the many commercial cultivars known to the present inventor, the most similar in comparison to ‘Fismerk’ are the varieties ‘Mercury’, U.S. Plant Pat. No. 5,929, and ‘Fisgrand’, U.S. Plant Pat. No. 8,760.

In comparison to ‘Mercury’, ‘Fismerk’ has a somewhat taller plant habit, rounder umbels, and leaves with distinct zonation, while ‘Mercury’ has no zonation. In comparison to ‘Fisgrand’, ‘Fismerk’ has a more intense flower color, shorter peduncles, smaller leaves, and a more compact plant habit.

In comparison to the male parent, ‘Fismerk’ has smaller foliage, longer peduncles, and slightly weaker zonation.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying photographic drawing shows typical flower and foliage characteristics of ‘Fismerk’ with colors being as true as possible with an illustration of this type. The measurements were taken in Langley, British Columbia, Canada, on Jul. 20, 2000, 15 weeks after planting of rooted cuttings into 6 inch pots. The plants had not been pinched.

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 green-house in May 2000 in Hillscheid, Germany.
