Abstract

A new and distinct cultivar of Caladium plant named ‘Burning Heart’, characterized by its intermediate height, upright and uniform plant habit; vigorous growth habit; rapid growth rate; fancy-type leaves with upper leaf surface bronze in color with contrasting salmon orange-colored spots and lower leaf surface greyed green in color; and good landscape performance.

Description

Botanical designation: Caladium×hortulanum.
Cultivar denomination: ‘BURNING HEART’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Caladium plant, botanically known as Caladium×hortulanum, commercially referred to as a fancy leaf-type Caladium and hereinafter referred to by the name ‘Burning Heart’.
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, 2008 in Avon Park, Fla. of Caladium×hortulanum ‘Red Flash’, not patented, as the female, or seed, parent with Caladium×hortulanum ‘Twist N Shout’, 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 Zolfo Springs, Fla. in September, 2009.
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, 2010 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 ‘Burning Heart’. These characteristics in combination distinguish ‘Burning Heart’ as a new and distinct Caladium plant:
    • 1. Intermediate in height, upright and uniform plant habit.
    • 2. Vigorous growth habit and rapid growth rate.
    • 3. Fancy-type leaves with upper leaf surface bronze in color with contrasting salmon orange-colored spots and lower leaf surface, greyed green in color.
    • 4. Good landscape performance.
Plants of the new Caladium differ primarily from plants of the female 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 faster growing and produce finished plants about two to three weeks earlier than plants of ‘Red Flash’.
    • 3. Plants of the new Caladium and ‘Red Flash’ differ in leaf color as leaves of plants of ‘Red Flash’ are dark green in color with dark red-colored centers and primary veins and pink-colored spots.
    • 4. Plants of the Caladium and ‘Red Flash’ differ in leaf petiole coloration as leaf petioles of plants of ‘Red Flash’ are red pink to tan pink in color with darker-colored stippling, stripes and tessellations.
Plants of the new Caladium differ primarily from plants of the male parent, ‘Twist N Shout’, in the following characteristics:
    • 1. Plants of the new Caladium and ‘Twist N Shout’ differ in leaf shape and color as leaves of plants of ‘Twist N Shout’ are hastate in shape and olive green in color with coppery orange-colored blotches.
    • 2. Plants of the Caladium and ‘Twist N Shout’ differ in leaf petiole coloration as leaf petioles of plants of ‘Twist N Shout’ are light green in color.
Plants of the new Caladium can be compared to plants of Caladium×hortulanum ‘Postman Joyner’, not patented. In side-by-side comparisons, plants of the new Caladium differed primarily from plants of ‘Postman Joyner’ in the following characteristics:
    • 1. Plants of the new Caladium and ‘Postman Joyner’ differed in leaf color as leaves of plants of ‘Postman Joyner’ had red-colored centers with dark red-colored spots and dark green-colored margins.
    • 2. Plants of the new Caladium and ‘Postman Joyner’ differed in leaf petiole color as leaf petioles of plants of ‘Postman Joyner’ were close to black in color.
Plants of the new Caladium can also be compared to plants of Caladium×hortulanum ‘Frieda Hemple’, not patented. In side-by-side comparisons, plants of the new Caladium differed primarily from plants of ‘Frieda Hemple’ in the following characteristics:
    • 1. Plants of the new Caladium and ‘Frieda Hemple’ differed in leaf color as leaves of plants of ‘Frieda Hemple’ had red-colored centers and dark green-colored margins.
    • 2. Plants of the new Caladium and ‘Frieda Hemple’ differed in leaf petiole color as leaf petioles of plants of ‘Frieda Hemple’ were tan pink in color with dense blackish brown-colored stippling and streaks.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying photographs illustrate the overall appearance of the new Caladium plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Caladium plant.
The photograph on the first sheet is a side perspective view of a typical plant of ‘Burning Heart’ in a container and grown in a shadehouse (tuber not de-eyed).
The photograph at the top of the second sheet is a comparison view of typical potted plants of the female parent, ‘Red Flash’ (left), ‘Burning Heart’ (center) and the male parent, ‘Twist N Shout’ (right).
The photograph at the bottom of the second sheet is a comparison view of typical potted plants of ‘Postman Joyner’ (left), ‘Burning Heart’ (center) and ‘Frieda Hemple’ (right).
The photograph at the top of the third sheet is a comparison view of typical plants of ‘Burning Heart’ grown in containers; the plant on the left has not had its tuber de-eyed and the plant on the right has had its tuber de-eyed prior to planting.
The photograph at the bottom of the third sheet is a close-up view of typical freshly-harvested tubers and roots of ‘Burning Heart’ plants.
The photograph on the fourth sheet is a side perspective view of typical plants of ‘Burning Heart’ grown in an open field.
 DETAILED BOTANICAL DESCRIPTION
The aforementioned photographs and following observations and measurements describe plants grown in 15-cm containers in a polypropylene-covered shadehouse (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 shadehouse and outdoor nursery production. During the production of the shadehouse-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 8,000 foot-candles. 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 light levels ranged from about 10,000 to 12,000 foot-candles. Plants grown in the shadehouse were seven weeks old, and plants grown in the outdoor nursery were eight 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 Edition, except where general terms of ordinary dictionary significance are used.
