Abstract

A new and distinct cultivar of Caladium plant named ‘FRH OF13-246’, characterized by its upright plant habit and tall in height; dense, leafy and bushy appearance; moderately vigorous growth habit and rapid growth rate; fancy-type leaves that have deep red-colored centers surrounded by dark green flushed with dark red-colored marginal areas and dark red-colored venation; and petioles that are close to black in color.

Description

Botanical designation: Caladium X hortulanum.
Cultivar denomination: ‘FRH OF13-246’.
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 OF13-246’.
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 2012 in Avon Park, Florida of Caladium X hortulanum ‘RUF 1522-3’, disclosed in U.S. Plant Pat. No. 33,615, as the female, or seed, parent with Caladium X hortulanum ‘Frieda Hemple’, 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, Florida in September 2013.
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, Florida since April 2014 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 OF13-246’. These characteristics in combination distinguish ‘FRH OF13-246’ as a new and distinct Caladium plant:
    • 1. Upright plant habit and tall in height; dense, leafy and bushy appearance.
    • 2. Moderately vigorous growth habit and rapid growth rate.
    • 3. Fancy-type leaves that have deep red-colored centers surrounded by dark green flushed with dark red-colored marginal areas and dark red-colored venation.
    • 4. Petioles that are close to black in color.
Plants of the new Caladium differ primarily from plants of the female parent, ‘RUF 1522-3’, in the following characteristics:
    • 1 Plants of the new Caladium are taller and more upright than plants of plants of ‘RUF 1522-3’.
    • 2. Leaves of plants of the new Caladium are not as thick as leaves of plants of ‘RUF 1522-3’.
    • 3. Leaves of plants of the new Caladium have deep red-colored centers surrounded by dark green flushed with dark red-colored marginal areas and dark red-colored venation whereas leaves of plants of ‘RUF 1522-3’ are dark red in color with dark green-colored margins.
    • 4. Petioles of plants of the new Caladium are close to black in color whereas petioles of plants of ‘RUF 1522-3’ are tannish pink in color with greenish brown-colored stripes, streaks, stippling and tessellations.
Plants of the new Caladium differ primarily from plants of the male parent, ‘Frieda Hemple’, in the following characteristics:
    • 1. Plants of the new Caladium are taller than plants of ‘Frieda Hemple’.
    • 2. Leaves of plants of the new Caladium have deep red-colored centers surrounded by dark green flushed with dark red-colored marginal areas and dark red-colored venation whereas leaves of plants of ‘Frieda Hemple’ are medium green in color with bright red-colored centers and venation.
    • 3. Petioles of plants of the new Caladium are close to black in color whereas 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 be compared to plants of Caladium X hortulanum ‘Postman Joyner’, not patented. In side-by-side comparisons, plants of the new Caladium differ primarily from plants of ‘Postman Joyner’ in leaf color as leaves of plants of the new Caladium have deep red-colored centers surrounded by dark green flushed with dark red-colored marginal areas and dark red-colored venation whereas leaves of plants of ‘Postman Joyner’ are dark green in color with bright red-colored centers.
Plants of the new Caladium can also be compared to plants of Caladium X hortulanum ‘Red Flash’, not patented. In side-by-side comparisons, plants of the new Caladium differ primarily from plants of ‘Red Flash’ in the following characteristics:
    • 1. Plants of the new Caladium are more vigorous and grow more rapidly than plants of ‘Red Flash’.
    • 2. Plants of the new Caladium are not as dense as plants of ‘Red Flash’.
    • 3. Leaves of plants of the new Caladium have deep red-colored centers surrounded by dark green flushed with dark red-colored marginal areas and dark red-colored venation whereas leaves of plants of ‘Red Flash’ have red-colored venation and interveinal areas with pink and white-colored spots and dark green-colored borders.
    • 4. Petioles of plants of the new Caladium are close to black in color whereas petioles of plants of ‘Red Flash’ are reddish pink to tannish pink in color with darker-colored stippling and stripes.

 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, Florida and plants grown in ground beds under full sunlight conditions in an outdoor nursery in Crewsville, Florida. 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 28° C. to 33° C., night temperatures ranged from about 22° C. to 25° C. and light levels were about 1,300 μmol. During the production of the outdoor nursery-grown plants, day temperatures ranged from about 29° C. to 35° C., night temperatures ranged from about 23° C. to 26° C. and full sunlight conditions. Plants grown in the shade house were eight weeks old and plants grown in the outdoor nursery were seven 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 terms of ordinary dictionary significance are used.
