Abstract

A new and distinct cultivar of Caladium plant named ‘Scarlet Flame’, characterized by its compact, upright and uniformly mounding plant habit; vigorous growth habit and rapid growth rate; lance-type leaves that are dark green in color with rose red-colored venation and interveinal areas and pink-colored blotches; and good landscape performance.

Description

Botanical designation: Caladium×hortulanum.
Cultivar denomination: ‘SCARLET FLAME’.
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 ‘Scarlet Flame’.
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 June, 2006 in Avon Park, Fla. of Caladium×hortulanum ‘John Peed’, not patented, as the female, or seed, parent with Caladium×hortulanum ‘Candyland’, disclosed in U.S. Plant Pat. No. 18,766, 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. on Sep. 15, 2007.
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, 2008 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 ‘Scarlet Flame’. These characteristics in combination distinguish ‘Scarlet Flame’ 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 dark green in color with rose red-colored venation and pink and rose red-colored spots and blotches.
    • 4. Good landscape performance.
Plants of the new Caladium differ primarily from plants of the female parent, ‘John Peed’, in leaf shape and color as plants of ‘John Peed’ have fancy-type leaves that are dark green in color with red-colored venation. In addition, plants of the new Caladium are more compact than plants of ‘John Peed’.
Plants of the new Caladium differ primarily from plants of the male parent, ‘Candyland’, in the following characteristics:
    • 1. Plants of the new Caladium are more compact than plants of ‘Candyland’.
    • 2. Plants of the new Caladium and ‘Candyland’ differ in leaf coloration as leaves of plants of ‘Candyland’ were white to grey-green in color with random pink-colored spots and green-colored margins.
    • 3. Plants of the Caladium and ‘Candyland’ differ in leaf petiole coloration as leaf petioles of plants of ‘Candyland’ are tan in color with dark green-colored stippling, streaks and tessellations.
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 denser than and not as open as plants of ‘Florida Sweetheart’.
    • 2. Plants of the new Caladium and ‘Florida Sweetheart’ differed in leaf coloration as leaves of plants of ‘Florida Sweetheart’ had lighter rose red-colored centers and dark green-colored margins.
Plants of the new Caladium can be compared to plants of Caladium×hortulanum ‘Lance Whorton’, not patented. In side-by-side comparisons, plants of the new Caladium differed primarily from plants of ‘Lance Whorton’ in the following characteristics:
    • 1. Plants of the new Caladium grew faster and produced finished plants about one week earlier than plants of ‘Lance Whorton’.
    • 2. Plants of the new Caladium were denser than and not as open as plants of ‘Lance Whorton’.
    • 3. Plants of the new Caladium had broader leaves than plants of ‘Lance Whorton’.
    • 4. Plants of the new Caladium and ‘Lance Whorton’ differed in leaf coloration as leaves of plants of ‘Lance Whorton’ were dark green in color with pink-colored spots, lighter green-colored blotches and rose red-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 nine 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.
