USPP16553P2 - Geranium plant named ‘Grafire’ - Google Patents

Abstract

A new and distinct cultivar of geranium plant named ‘Grafire’ particularly characterized by the combined features of brilliant red, star-shaped, single-type flowers; numerous, umbrella-shaped inflorescences, well above the foliage; medium sized, green, fan-shaped leaves with strong zonation; medium sized, rounded and well-branched plant habit; an beginning of flowering in mid season with continuous flowering.

Description

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

Variety denomination: ‘Grafire’.

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 ‘Grafire’.

‘Grafire’ is a product of a planned breeding program which had the objective of creating new stellar-type germanium cultivars in various flower colors, in combination with early flowering, zoned foliage, and about medium sized, rounded and well-branched plant habit.

‘Grafire’ originated from a hybridization made by the inventor, Angelika Utecht, in a controlled breeding program in Hellscheid, Germany, in 1999. The female parent was an unpatented hybrid plant, no. 88-380-1, having small, red single-type flowers, medium green foliage with distinct zonation, and relatively compact plant habit. The male parent of ‘Grafire’ was the unpatented commercial variety ‘Vectis Glitter’, with single-type, white flowers with irregularly spread small red dots or fine stripes, large inflorescences, and vigorous growth habit.

‘Grafire’ 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 ‘Grafire’ was accomplished when vegetative cuttings were taken from the initial selection in the fall of 2000 in a controlled environment in Fuerteventura, 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 ‘Grafire’ are firmly fixed and are retained through successive generations of asexual reproduction.

BRIEF SUMMARY OF THE INVENTION

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

• • 1. brillant red, single-type flowers;
  • 2. medium sized, umbrella-shaped inflorescences, well above the foliage;
  • 3. medium sized, fan-shaped leaves with strong zonation;
  • 4. medium sized and well-branched plant habit; and
  • 5. beginning of flowering in mid season.

Of the many commercial cultivars known to the present inventor, the most similar in comparison to ‘Grafire’ are the patented variety ‘Fiwoscarl’ (U.S. Plant Pat. No. 13,303) and the unpatented variety ‘Red Flash’, also known by breeder's ref. KLEP01002.

In comparison to ‘Fiwoscarl’, ‘Grafire’ has similar flower size and color, but roughly semi-circular leaf blades whereas the leaves of ‘Fiwoscarl’ are kidney-shaped. Further, the plant habit of ‘Fiwoscarl’ is generally taller and with a higher foliage canopy than ‘Grafire’.

In comparison to ‘Red Flash’, with numerous small inflorescence, and compact plant habit, ‘Grafire’ has larger and flatter shaped umbels, foliage with less strong zonation, and taller, medium sized, plant habit.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying photographic drawing shows typical flower and foliage characteristics of ‘Grafire’ with colors being as true as possible with an illustration of this type. The photographic drawing shows a side view perspective of a flowering potted plant of ‘Grafire’ with leaves, buds and inflorescences.

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.
