Geranium plant named ‘Fismaxi’

Abstract

A new and distinct cultivar of geranium plant named ‘Fismaxi’, particularly characterized by the combined features of large, brilliant red, double-type flowers; numerous medium-sized, semi-spherically shaped inflorescences; deep green foliage with weak zonation, initially round and bushy, and later, somewhat trailing plant habit; and early spring flowering response.

Description

Genus and species of the plant claimed: Pelargonium peltatum L'Héritier (hybrid).

Variety denomination: ‘Fismaxi’.

BACKGROUND OF THE INVENTION

The present invention comprises a new and distinct cultivar of geranium, botanically known as Pelargonium peltatum, and hereinafter referred to by the cultivar name ‘Fismaxi’.

‘Fismaxi’ is a product of a planned breeding program which had the objective of creating new ivy geranium cultivars with semi-double to double flower type, zoned foliage, and about medium sized, well-branched growth habit, in various flower colors.

‘Fismaxi’ originated from a hybridization made by the inventor, Angelika Utecht, in a controlled breeding program in Hillscheid, Germany, in 2000.

The female parent was an unpatented hybrid plant, no. 97-2379-5, derived from a cross between the varieties ‘Fiscoral’ (U.S. Plant Pat. No. 12,995) and ‘Fizzard’ (U.S. Plant Pat. No. 10,992). The resulting seedling was characterized by orange-red flowers, deep green foliage, and about medium growth habit. The male parent of ‘Fismaxi’ was the unpatented plant No. 93-361-3, having deep red, semi-double flowers, large leaves with slight zonation, and long, trailing plant habit.

‘Fismaxi’ was selected as one flowering plant within the progeny of the stated cross by Angelika Utecht in 2001 in a controlled environment in Galdar, Gran Canaria, Spain.

The first act of asexual reproduction of ‘Fismaxi’ was accomplished when vegetative cuttings were taken from the initial selection in the fall of 2001, 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 of 2002 in Hillscheid, Germany, and continuing thereafter, has demonstrated that the combination of characteristics as herein disclosed for ‘Fismaxi’ are firmly fixed and are retained through successive generations of asexual reproduction.

BRIEF SUMMARY OF THE INVENTION

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

• • 1. large, brilliant red, double-type, flowers;
  • 2. medium sized, semi-spherically shaped inflorescences;
  • 3. deep green foliage with weak zonation;
  • 4. medium growth habit, and very well-branched, round plant habit; and
  • 5. early spring flowering response and rich flowering.

Of the many commercial cultivars known to the present inventor, the most similar ones are the patented varieties ‘Fip 101’ (U.S. Plant Pat. No. 14,008) and ‘Fisbeach’ (U.S. Plant Pat. No. 12,408).

In comparison to ‘Fip 101’, ‘Fismaxi’ has a slightly more scarlet or orange-red hue of flower color, larger inflorescences, even weaker zonation on foliage, and taller plant habit. In comparison to ‘Fisbeach’, inflorescences of ‘Fismaxi’ appear relatively close, but its growth habit is much less vigorous, and the diameter of plants measures roughly half the size by the end of summer. Furthermore, ‘Fismaxi’ develops at least weak zonation on leaves, and beginning of flowering is earlier.

BRIEF DESCRIPTION OF THE DRAWINGS

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

The photographic drawing shows as FIG. 1 a close-up view of a branch end of ‘Fismaxi’ with leaves, buds and inflorescences; and as

FIG. 2 a side perspective view of a flowering hanging basket of ‘Fismaxi’ with leaves, buds and inflorescences.
