Abstract

A new and distinct cultivar of Geranium plant named ‘TOSTD0188’, characterized by its semi-double type, dark reddish-orange colored flowers, dark green-colored foliage having zonation, and moderately vigorous, upright-mounded growth habit, is disclosed.

Description

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

Variety denomination: ‘TOSTD0188’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Geranium plant botanically known as Pelargonium x hortorum and hereinafter referred to by the cultivar name ‘TOSTD0188’.

The new cultivar originated in a controlled breeding program in Hendrik-Ido-Ambacht, the Netherlands during July 2015. 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-mounded growth habit.

The new Geranium cultivar is the result of cross-pollination. The female (seed) parent of the new cultivar is Shocking Orange ‘Pacshorg’, U.S. Plant Pat. No. 22,043, characterized by its semi-double type, bright orange-colored flowers, dark green-colored foliage having zonation, and vigorous, upright and rounded growth habit. The male (pollen) parent of the new cultivar is the proprietary Pelargonium x hortorum breeding selection coded TA0057, not patented, characterized by its semi-double type, medium orange-colored flowers, dark green-colored foliage having zonation, low vigor and an upright-mounded growth habit. The new cultivar was discovered and selected as a single flowering plant within the progeny of the above stated cross-pollination during August 2016 in a controlled environment in Hendrik-Ido-Ambacht, the Netherlands.

Asexual reproduction of the new cultivar by terminal stem cuttings since August 2016 in Hendrik-Ido-Ambacht, the Netherlands 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 ‘TOSTD0188’ as a new and distinct cultivar of Geranium plant:

- 1. Semi-double type, dark reddish-orange colored flowers;
- 2. Dark green-colored foliage with zonation; and
- 3. Moderately vigorous, upright-mounded growth habit.

Plants of the new cultivar differ from plants of the female parent primarily in having a darker colored leaf zonation and a small diameter inflorescence. Plants of the new cultivar differ from plants of the male parent primarily in having increased growth vigor.

Of the many commercially available Geranium cultivars, the most similar in comparison to the new cultivar is Savannah Oh So Orange ‘Duesaoran’, U.S. Plant Pat. No. 26,144. However, in side-by-side comparisons, plants of the new cultivar differ from plants of ‘Duesaoran’ in at least the following characteristics:

- 1. Plants of the new cultivar have a darker colored leaf zonation than plants of ‘Duesaoran’;
- 2. Plants of the new cultivar have a flower color that has less red coloration than plants of ‘Duesaoran’; and
- 3. Plants of the new cultivar are shorter than plants of ‘Duesaoran’.

The new cultivar can also be compared to Dynamo Orange ‘TOSTC0563’, co-pending application. However, in side-by-side comparison, plants of the new cultivar differ from plants of ‘TOSTC0563’ in at least the following characteristics:

- 1. Plants of the new cultivar have flowers with less red coloration than plants of ‘TOSTC0563’;
- 2. Plants of the new cultivar have a darker colored leaf zonation than plants of ‘TOSTC0563’; and
- 3. Plants of the new cultivar have fewer petals per flower than plants of ‘TOSTC0563’.

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 ‘TOSTD0188’. The plants were approximately 4 months old and grown in 4.5-inch pots for approximately 14 weeks in a greenhouse in West Chicago, Ill.

FIG. 1 illustrates a side view of the overall growth and flowering habit of ‘TOSTD0188’.

FIG. 2 illustrates a close-up view of an individual umbel of ‘TOSTD0188’.

FIG. 3 illustrates a close-up view of an individual leaf of ‘TOSTD0188’.

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 April 2019 under natural light conditions in West Chicago, Ill.

The following descriptions and measurements describe approximately 4-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.
