Abstract

A new and distinct cultivar of Caladium plant named ‘Flare’, characterized by its compact, upright and uniformly mounding plant habit; vigorous growth habit and rapid growth rate; lance-type leaves that are shiny in luster with rose red-colored centers surrounded by a greyed green and pink-colored speckling and dark green-colored margins; and good landscape performance.

Description

Botanical designation: Caladium×hortulanum.
Cultivar denomination: ‘FLARE’.
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 lance (strap) leaf-type Caladium and hereinafter referred to by the name ‘Flare’.
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, 2007 in Lake Placid, Fla. of Caladium×hortulanum ‘White Christmas’, not patented, as the female, or seed, parent with Caladium×hortulanum ‘Rosemary’, disclosed in U.S. Plant Pat. No. 20,993, 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. on Sep. 15, 2008.
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 Apr. 15, 2009 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 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 ‘Flare’. These characteristics in combination distinguish ‘Flare’ as a new and distinct Caladium plant:
    • 1. Compact, upright and uniformly mounding plant habit.
    • 2. Vigorous growth habit and rapid growth rate.
    • 3. Lance-type leaves that are shiny in luster with rose red-colored centers surrounded by a greyed green and pink-colored speckling and dark green-colored margins.
    • 4. Good landscape performance.
Plants of the new Caladium differ primarily from plants of the female parent, ‘White Christmas’, in leaf shape and color as plants of ‘White Christmas’ have broad fancy-type white-colored leaves with distinct dark green-colored venation and margins. In addition, plants of the new Caladium are more compact than plants of ‘White Christmas’.
Plants of the new Caladium differ primarily from plants of the male parent, ‘Rosemary’, in leaf and leaf petiole color as plants of ‘Rosemary’ have leaves that are darker rose red in color with mottled light and dark green-colored borders and leaf petioles that are tan pink to tan green in color with greenish brown-colored stippling. In addition, plants of the new Caladium are more compact than plants of ‘Rosemary’.
Plants of the new Caladium can be compared to plants of Caladium×hortulanum ‘Florida Sweetheart’, disclosed in U.S. Plant Pat. No. 8,526. In side-by-side comparisons, plants of the new Caladium differed primarily from plants of ‘Florida Sweetheart’ in the following characteristics:
    • 1. Plants of the new Caladium were more upright than plants of ‘Florida Sweetheart’.
    • 2. Plants of the new Caladium grew faster and produced finished plants about one week earlier than plants of ‘Florida Sweetheart’.
    • 3. Plants of the new Caladium and ‘Florida Sweetheart’ differed in leaf luster and coloration as leaves of plants of ‘Florida Sweetheart’ were dull and had lighter rose red-colored centers and dark green-colored margins.
Plants of the new Caladium can be compared to plants of Caladium×hortulanum ‘Pink Symphony’, not patented. In side-by-side comparisons, plants of the new Caladium differed primarily from plants of ‘Pink Symphony’ in the following characteristics:
    • 1. Plants of the new Caladium were more compact than plants of ‘Pink Symphony’.
    • 2. Plants of the new Caladium grew faster and produced finished plants about one to two weeks earlier than plants of ‘Pink Symphony’.
    • 3. Plants of the new Caladium had broader leaves than plants of ‘Pink Symphony’.
    • 4. Plants of the new Caladium and ‘Pink Symphony’ differed in leaf luster and coloration as leaves of plants of ‘Pink Symphony’ were dull with mostly pink or pale pink-colored centers surrounded by a green-colored border with white to greenish white-colored venation.
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.

 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 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 plants, day temperatures ranged from about 29° C. to 33° C. (shadehouse) or 29° C. to 35° C. (outdoor nursery), night temperatures ranged from about 22° C. to 25° C. (shadehouse) or 23° C. to 26° C. (outdoor nursery) and light levels were about 8,000 foot-candles (shadehouse) or 10,000 to 12,000 foot-candles (outdoor nursery). Plants grown in the shadehouse 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 Edition, except where general terms of ordinary dictionary significance are used.
