Abstract

A new and distinct cultivar of Osteospermum plant named ‘Balsercoric’, characterized by its medium coral-red and light purple colored inflorescences, dark green-colored foliage, and moderately vigorous, upright-mounded growth habit, is disclosed.

Description

Latin name of genus and species of plant claimed: Osteospermum ecklonis.

Variety denomination: ‘Balsercoric’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Osteospermum plant botanically known as Osteospermum ecklonis and hereinafter referred to by the cultivar name ‘Balsercoric’.

The new cultivar originated in a controlled breeding program in Santa Paula, Calif. during summer 2014. The objective of the breeding program was the development of Osteospermum cultivars that are freely flowering with unique flower coloration and a freely branching, upright-mounded growth habit.

The new Osteospermum cultivar is the result of open-pollination. The female (seed) parent of the new cultivar is the proprietary Osteospermum ecklonis breeding selection coded 58952-2, not patented, characterized by its coral-orange colored inflorescences having a large purple-colored center, medium green-colored foliage, and moderately vigorous, upright-mounded growth habit. The male (pollen) parent of the new cultivar is unknown. The new cultivar was discovered and selected as a single flowering plant within the progeny of the above stated open-pollination during February 2015 in a controlled environment in Santa Paula, Calif.

Asexual reproduction of the new cultivar by terminal stem cuttings since February 2015 in Santa Paula, Calif. and Arroyo Grande Calif. 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 ‘Balsercoric’ as a new and distinct cultivar of Osteospermum plant:

- 1. Medium coral-red and light purple colored inflorescences;
- 2. Dark green-colored foliage; and
- 3. Moderately vigorous, upright-mounded growth habit.

Plants of the new cultivar differ from plants of the female parent primarily in having inflorescences with a larger diameter, a redder shade of coral, and a smaller and lighter purple-colored center.

Of the many commercially available Osteospermum cultivars, the most similar in comparison to the new cultivar is Blue Eyed Beauty ‘Balostlueye’, U.S. Plant Pat. No. 26,150. However, in side-by-side comparison, plants of the new cultivar differ from plants of ‘Balostlueye’ in at least the following characteristics:

- 1. Plants of the new cultivar have a ray floret color that is more red with a lighter purple-colored center than plants of ‘Balostlueye’; and
- 2. Plants of the new cultivar have more branches per plant than plants of ‘Balostlueye’.

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 may differ slightly from the color values cited in the detailed description, which accurately describes the colors of ‘Balsercoric’. The plants were grown in 4.5-inch pots for 14 weeks in a greenhouse in West Chicago, Ill.

FIG. 1 illustrates a side view of the overall growth and flowering habit of ‘Balsercoric’.

FIG. 2 illustrates a close-up view of an individual inflorescence of ‘Balsercoric’.

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, 2015 edition, except where general color terms of ordinary significance are used. The color values were determined in May 2019 under natural light conditions in West Chicago, Ill.

The following descriptions and measurements describe approximately 6-month old 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 4.5-inch pots for approximately 14 weeks utilizing a soilless growth medium. Greenhouse temperatures were maintained at approximately 67° F. to 72° F. (19° C. to 22° C.) during the day and approximately 65° F. to 68° F. (18° C. to 20° C.) during the night. Supplemental lighting was used. Measurements and numerical values represent averages of typical plants.
