Geranium plant named ‘Fistufru’

Abstract

A new and distinct cultivar of geranium plant named ‘Fistufru’, particularly characterized by the combined features of rose-red, open flowers, with deep-red macules on petals; almost single-type flowers on long peduncles; medium green foliage with weak, narrow zonation; moderately vigorous plant growth; initially round and bushy, and later, long trailing plant habit; and mid-spring season flowering response.

Description

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

Variety denomination: ‘Fistufru’.

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 ‘Fistufru’.

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

‘Fistufru’ originated from a hybridization made by the inventor, Angelika Utecht, in a controlled breeding program in Hillscheid, Germany, in 1999. The female parent of ‘Fistufru’ was the patented variety ‘Fisam’ (U.S. Plant Pat. No. 8,327), and is described as having light violet, double flowers, medium green foliage with strong zonation, and moderately vigorous growth habit. The male parent of ‘Fistufru’ was the unpatented plant No. 93-361-3, which was characterized by red, semi-double flowers, foliage with weak zonation, and relatively tall plant habit.

‘Fistufru’ was selected as one flowering plant within the progeny of the stated cross by Angelika Utecht in 2000 in a controlled environment in Fuerteventura, Canary Islands, Spain.

The first act of asexual reproduction of ‘Fistufru’ was accomplished when vegetative cuttings were taken from the initial selection in the fall of 2000 in a controlled environment in Fuerteventura, Canary Islands, Spain, by, or under the supervision of, Angelika Utecht.

Horticultural examination of plants grown from cuttings of the plant initiated in May of 2001 in Hillscheid, Germany, and continuing thereafter, has demonstrated that the combination of characteristics as herein disclosed for ‘Fistufru’ are firmly fixed and are retained through sucessive generations of asexual reproduction.

BRIEF SUMMARY OF THE INVENTION

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

• • 1. rose-red flowers with large, deep-red macules on upper petals;
  • 2. almost single-type flowers on long peduncles;
  • 3. medium green foliage with weak zonation;
  • 4. moderately vigorous growth, trailing plant habit;
  • 5. about mid-spring flowering response; and
  • 6. good weather resistance of the flowers.

Of the many commercial cultivars known to the present inventor, there is no cultivar very close in comparison. However, ‘Fistufru’ might be compared with ‘Fisdream’ (U.S. Plant Pat. No. 14,920).

In comparison to ‘Fisdream’, ‘Fistufru’ has flowers of a roughly similar overall color, but there are dark-red flares on petals, and generally fewer petals per flower. Furthermore, ‘Fistufru’ does not grow quite as vigorously.
