Geranium plant named ‘Sil Baldo 448’

Abstract

A new and distinct cultivar of Geranium plant named ‘Sil Baldo 448’, characterized by its semi-double type, fuchsia and cherry-red bicolored flowers, dark green-colored foliage, low to moderate vigor, and compact, upright growth habit growth habit, is disclosed.

Description

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

Variety denomination: ‘Sil Baldo 448’.

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 ‘Sil Baldo 448’.

The new cultivar originated in a controlled breeding program in Weener, Germany, California during June through December 2004. 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 moderately vigorous, upright growth habit.

The new Geranium cultivar is the result of cross-pollination. The female (seed) parent of the new cultivar is ‘SEL Lucky’, not patented, characterized by its double-type, bluish red to purple colored flowers, dark green-colored foliage, and moderately vigorous, upright growth habit. The male (pollen) parent of the new cultivar is the proprietary Pelargonium×hortorum breeding selection designated E 065, not patented, characterized by its single-type, fuchsia and cherry-red bicolored flowers, dark green-colored foliage, low vigor, and compact, upright growth habit. The new cultivar was discovered and selected as a single flowering plant within the progeny of the above stated cross-pollination during June through August 2005 in a controlled environment at Weener, Germany.

Asexual reproduction of the new cultivar by terminal stem cuttings since August 2005 at Weener, Germany, Arroyo Grande, Calif. and West Chicago, Ill. has demonstrated that the new cultivar reproduces true to type with all of the 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 ‘Sil Baldo 448’ as a new and distinct cultivar of Geranium plant:

• • 1. Semi-double type, fuchsia and cherry-red bicolored flowers;
  • 2. Dark green-colored foliage;
  • 3. Low to moderate vigor; and
  • 4. Compact, upright growth habit.

Plants of the new cultivar differ from plants of the female parent primarily in flower type and growth vigor and from plants of the male parent primarily in flower type and growth vigor. The new cultivar is slightly more vigorous than the male parent.

Of the many commercially available Geranium cultivars, the most similar in comparison to the new cultivar is Designer Light Pink Sizzle ‘Baldeslipzle’, U.S. Plant Pat. No. 18,863. However, in side by side comparisons, plants of the new cultivar differ from plants of ‘Baldeslipzle’ in at least the following characteristics:

• • 1. Plants of the new cultivar have a darker flower color than plants of ‘Baldeslipzle’; and
  • 2. Plants of the new cultivar have a darker foliage color than plants of ‘Baldeslipzle’.

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 ‘Sil Baldo 448’. The plants were grown in 4-inch pots for 7 weeks in a greenhouse at West Chicago, Ill.

FIG. 2 illustrates a close-up view of an individual umbel of ‘Sil Baldo 448’.

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 in August 2010 under natural light conditions in West Chicago, Ill.

The following descriptions and measurements describe plants produced from cuttings from stock plants and grown in a glass-covered greenhouse under conditions comparable to those used in commercial practice. The plants were grown in West Chicago, Ill. in 4-inch pots for 7 weeks utilizing a soilless growth medium. Greenhouse temperatures were maintained at approximately 70° F. to 77° F. (21° C. to 25° C.) during the day and approximately 65° F. to 68° F. (18° C. to 20° C.) during the night. Greenhouse light levels of 2,500 footcandles to 6,000 footcandles were maintained during the day. Measurements and numerical values represent averages of typical plants.
