Description

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

Variety denomination: ‘Ballurscar’.

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 by the cultivar name ‘Ballurscar’.

The new cultivar originated in a controlled breeding program in Arroyo Grande, Calif. during May 2003. The objective of the breeding program was the development of Geranium cultivars with unique flower coloration, medium green-colored foliage, and a vigorous, upright growth habit.

The new Geranium cultivar is the result of cross-pollination. The female (seed) parent of the new cultivar is Rumba Fire ‘Fisfire’, U.S. Plant Pat. No. 12,489, characterized by its semi-double type dark scarlet-colored flowers, medium green-colored foliage with distinct zone, and mounded growth habit. The male (pollen) parent of the new cultivar is Rocky Mountain™ Red ‘Fip 553’, U.S. Plant Pat. No. 13,961, characterized by its semi-double type deep red-colored flowers, medium green-colored foliage with medium zone, and 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 May 2004 in a controlled environment at Arroyo Grande, Calif.

Asexual reproduction of the new cultivar by terminal stem cuttings since May 2004 at 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 ‘Ballurscar’ as a new and distinct cultivar of Geranium plant:

    • 1. Semi-double type, medium red scarlet-colored flowers;
    • 2. Medium green-colored foliage with strong zonation; and
    • 3. Vigorous, upright growth habit.

Plants of the new cultivar differ from plants of the female parent primarily in foliage color and plant height. The female parent has stronger zonation and is taller than plants of the new cultivar. Plants of the new cultivar differ from plants of the male parent primarily in flower color and umbel size. The male parent has darker red-colored flowers and has larger umbels than plants of the new cultivar.

Of the many commercially available Geranium cultivars known to the inventor, the most similar in comparison to the new cultivar is Rocky Mountain™ Dark Red ‘Fisrodark’ U.S. Plant Pat. No. 15,513. However, in side by side comparisons, plants of the new cultivar differ from plants of ‘Fisrodark’ in the following characteristics:

    • 1. Plants of the new cultivar have a stronger zonation color than plants of ‘Fisrodark’; and
    • 2. Plants of the new cultivar have a flower color that is lighter in color than plants of ‘Fisrodark’.

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 ‘Ballurscar’. The plants were grown in 4.5 inch pots for 8 weeks in a greenhouse at West Chicago, Ill. Plants were given one pinch at transplant.

FIG. 2 illustrates a close-up view of an individual umbel of ‘Ballurscar’.

FIG. 3 illustrates a close-up view of an individual leaf of ‘Ballurscar’.

 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 15, 2007 between 9:00 a.m. and 11:00 a.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 glass-covered greenhouse under conditions comparable to those used in commercial practice. The plants were grown at West Chicago, Ill. in 4.5 inch pots for 8 weeks utilizing a soilless growth medium. Plants were given one pinch at transplant. 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.
