Geranium plant named ‘Balfanwite’

Abstract

A new and distinct cultivar of Geranium plant named ‘Balfanwite’ characterized by its semi-double white-colored flowers, dark green-colored foliage, and medium to compact, upright growth habit.

Description

Latin name of genus and species of plant claimed: Pelargonium×hortorum.

Variety denomination: ‘Balfanwite’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Geranium plant botanically known as Pelargonium×hortorum and hereinafter referred to by the cultivar name ‘Balfanwite’.

The new cultivar originated in a controlled breeding program in Weener, Niedersachen (Northern Germany) during the summer of 1999. The objective of the breeding program was the development of Geranium cultivars that flower uniformly and have large flowers, dark green-colored foliage, and a vigorous, upright growth habit.

The female (seed) parent of the new cultivar was ‘Penwei’ (HU9801865 A2 and QZ1995/0756). The male (pollen) parent of the new cultivar was ‘Sel Wenke’, not patented. The new Geranium was discovered and selected by the inventor as a single flowering plant within the progeny of the above stated cross-pollination during June 2000 in a controlled environment at Weener, Niedersachen.

Asexual reproduction of the new cultivar by terminal stem cuttings since June 2000 at Weener, Niedersachen and West Chicago, Ill. has demonstrated that the new cultivar reproduces true to type with all characteristics, as herein described, firmly fixed and retained through successive generations of such asexual propagation.

SUMMARY OF THE INVENTION

The following characteristics of the new cultivar have been repeatedly observed and can be used to distinguish ‘Balfanwite’ as a new and distinct cultivar of Geranium plant:

• • 1. Semi-double white-colored flowers;
  • 2. Dark green-colored foliage; and
  • 3. Medium to compact, upright growth habit.

Plants of the new cultivar differ from plants of the female parent primarily in flower shape and growth habit and from plants of the male parent primarily in leaf color and growth habit.

Of the many commercially available Geranium cultivars known to the inventor, the most similar in comparison to the new cultivar is ‘Fisrowi’, U.S. Plant Pat. No. 12,389. However, in side by side comparisons, plants of the new cultivar differ from plants of ‘Fisrowi’ in the following characteristics:

• • 1. Plants of the new cultivar are more compact as measured by plant height than plants of ‘Fisrowi’; and
  • 2. Plants of the new cultivar have darker foliage color than plants of ‘Fisrowi’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs show, as nearly true as it is reasonably possible to make the same in color illustrations of this type, typical flower and foliage characteristics of the new cultivar. Colors in the photographs differ slightly from the color values cited in the detailed description, which accurately describes the colors of ‘Balfanwite’. The plants were grown in 10 cm pots for 10 weeks in a greenhouse at West Chicago, Ill.

DETAILED BOTANICAL DESCRIPTION

The new cultivar has not been observed under all possible environmental conditions to date. Accordingly, it is possible that the phenotype may vary somewhat with variations in the environment, such as temperature, light intensity, and day length, without, however, any variance in genotype.

The chart used in the identification of colors described herein is The R.H.S. Colour Chart of The Royal Horticultural Society, London, England, 2001 edition, except where general color terms of ordinary significance are used. The color values were determined on May 23, 2005 between 3:00 p.m. and 4:00 p.m. under natural light conditions, in West Chicago, Ill.

The following descriptions and measurements describe plants produced from cuttings taken from stock plants and grown in a double polycarbonate-covered greenhouse under conditions comparable to those used in commercial practice. The plants were grown at West Chicago, Ill. in 10 cm pots for 10 weeks utilizing a soilless growth medium. Greenhouse temperatures were maintained at approximately 65° F. to 75° F. (18° C. to 24° C.) during the day and approximately 62° F. to 68° F. (17° C. to 20° C.) during the night. Greenhouse light levels of 3,500 to 6,000 footcandles were maintained during the day.
