Description

Botanical designation: Caladium X hortulanum.

Cultivar denomination: ‘FRH OF15-107’.

STATEMENT REGARDING PRIOR DISCLOSURES BY INVENTOR/APPLICANT

The Inventor/Applicant asserts that no publications nor advertisements relating to sales, offers for sale or public distribution occurred more than one year prior to the effective filing date of this application. Any information about the claimed plant would have been obtained from a direct or indirect disclosure from the Inventor/Applicant. Inventor/Applicant claims a prior art exception under 35 U.S.C. 102(b)(1) for disclosure and/or sales prior to the filing date but less than one year prior to the effective filing date.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Caladium plant, botanically known as Caladium X hortulanum, commercially referred to as a fancy leaf-type Caladium and hereinafter referred to by the name ‘FRH OF15-107’.

The objective of the Inventor's breeding program is to create new Caladium plants that have uniform plant habit, exceptional container and garden performance and attractive and unique leaf coloration.

The new Caladium plant originated from a cross-pollination made by the Inventor in April, 2014 in Avon Park, Fla. of Caladium X hortulanum ‘UF 4424’, disclosed in U.S. Plant Pat. No. 25,598, as the female, or seed, parent with Caladium X hortulanum ‘Red Flash’, not patented, as the male, or pollen, parent. The new Caladium plant was discovered and selected by the Inventor as a single plant within the progeny of the stated cross-pollination in a controlled outdoor nursery environment in Avon Park, Fla. in September, 2015.

Asexual reproduction of the new Caladium plant by “chipping” the tubers (cutting the tuber into segments with each segment containing an axillary bud and tuber cortical tissue) in a controlled outdoor nursery environment in Zolfo Springs, Fla. since April, 2016 has shown that the unique features of this new Caladium plant are stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

Plants of the new Caladium have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘FRH OF15-107’. These characteristics in combination distinguish ‘FRH OF15-107’ as a new and distinct Caladium plant:

    • 1. Short to intermediate in height and mounding plant habit; dense, leafy and bushy appearance.
    • 2. Vigorous growth habit and rapid growth rate.
    • 3. Fancy-type leaves that are dark green in color with dark red-colored centers.
    • 4. First emerging leaves are glossy and later emerging leaves are duller in luster.
    • 5. Petioles that are reddish pink in color with dense brownish green-colored streaks.

Plants of the new Caladium differ primarily from plants of the female parent, ‘UF 4424’, in the following characteristics:

    • 1. Plants of the new Caladium are short to intermediate in height whereas plants of ‘UF 4424’ are short in height.
    • 2. Leaves of plants of the new Caladium are dark green in color with dark red-colored centers whereas leaves of plants of ‘UF 4424’ are dark red in color with narrow green-colored margins.
    • 3. Leaf petioles of plants of the new Caladium are reddish pink in color with dense brownish green-colored streaks whereas leaf petioles of plants of ‘UF 4424’ are greyed red in color.

Plants of the new Caladium differ primarily from plants of the male parent, ‘Red Flash’, in the following characteristics:

    • 1. Plants of the new Caladium are shorter than plants of ‘Red Flash’.
    • 2. Plants of the new Caladium are more mounding than and not as upright as plants of ‘Red Flash’.
    • 3. Plants of the new Caladium produce finished plants in 15-cm containers about two to three weeks earlier than plants of ‘Red Flash’.
    • 4. Leaves of plants of the new Caladium are dark green in color with dark red-colored centers whereas leaves of plants of ‘Red Flash’ have red-colored venation and intervenous areas with pink and white-colored spots and dark green-colored borders.
    • 5. Leaf petioles of plants of the new Caladium are reddish pink in color with dense brownish green-colored streaks whereas leaf petioles of plants of ‘Red Flash’ are reddish pink to tannish pink in color with darker-colored stippling and stripes.

Plants of the new Caladium can be compared to plants of Caladium X hortulanum ‘Frieda Hemple’, not patented. In side-by-side comparisons, plants of the new Caladium differ primarily from plants of ‘Frieda Hemple’ in the following characteristics:

    • 1. Plants of the new Caladium are shorter than plants of ‘Frieda Hemple’.
    • 2. Plants of the new Caladium are more mounding than and not as upright as plants of ‘Frieda Hemple’.
    • 3. Leaves of plants of the new Caladium are dark green in color with dark red-colored centers whereas leaves of plants of ‘Frieda Hemple’ are medium green in color with bright red-colored centers and venation.
    • 4. First emerged leaves of plants of the new Caladium are glossy whereas first emerged leaves of plants of ‘Frieda Hemple’ are dull in sheen.
    • 5. Leaf petioles of plants of the new Caladium are reddish pink in color with dense brownish green-colored streaks whereas leaf petioles of plants of ‘Frieda Hemple’ are tannish pink in color with dense brownish black-colored stippling and streaks.

Plants of the new Caladium can also be compared to plants of Caladium X hortulanum ‘Bombshell’, disclosed in U.S. Plant Pat. No. 23,817. In side-by-side comparisons, plants of the new Caladium differ primarily from plants of ‘Bombshell’ in the following characteristics:

    • 1. Plants of the new Caladium are shorter than plants of ‘Bombshell’.
    • 2. Plants of the new Caladium are more mounding than and not as upright as plants of ‘Bombshell’.
    • 3. Plants of the new Caladium produce finished plants in 15-cm containers about two weeks earlier than plants of ‘Bombshell’.
    • 4. Leaves of plants of the new Caladium are dark green in color with dark red-colored centers whereas leaves of plants of ‘Bombshell’ have dark red to greyed purple-colored venation and intervenous areas surrounded with dark green-colored borders.
    • 5. Leaf petioles of plants of the new Caladium are reddish pink in color with dense brownish green-colored streaks whereas leaf petioles of plants of ‘Bombshell’ are tannish pink in color with black-colored stippling.

 DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown in 15-cm containers in a polypropylene-covered shade house (30% light reduction) in Avon Park, Fla. and plants grown in ground beds under full sunlight conditions in an outdoor nursery in Crewsville, Fla. The plants were grown under cultural practices typical of commercial shade house and outdoor nursery production. During the production of the shade house-grown plants, day temperatures ranged from about 28C to 33C, night temperatures ranged from about 22C to 25C and light levels were about 1,300 μmol. During the production of the outdoor nursery-grown plants, day temperatures ranged from about 29C to 35C, night temperatures ranged from about 23C to 26C and full sunlight conditions. Plants grown in the shade house were six weeks old and plants grown in the outdoor nursery were six months old when the photographs and the detailed description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2001 and 2015 Editions, except where general tetms of ordinary dictionary significance are used.
