Description

Botanical designation: Caladium X hortulanum.
Cultivar denomination: ‘LWH OF13-332’.
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 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 lance leaf-type Caladium and hereinafter referred to by the name ‘LWH OF13-332’.
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, Fla. of Caladium X hortulanum ‘Florida Sweetheart’, disclosed in U.S. Plant Pat. No. 8,526, as the female, or seed, parent with Caladium X hortulanum ‘Scarlet Flame’, disclosed in U.S. Plant Pat. No. 25,419, 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, 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, Fla. 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 ‘LWH OF13-332’. These characteristics in combination distinguish ‘LWH OF13-332’ as a new and distinct Caladium plant:
    • 1. Intermediate in height and mounding plant habit; dense and bushy appearance.
    • 2. Vigorous growth habit and rapid growth rate.
    • 3. Lance-type leaves that are light red to variable shades of pink in color with random green and orange-colored spots with dark bronze red-colored venation and margins.
    • 4. Petioles that are black or black with tannish pink stripes in color.
Plants of the new Caladium differ primarily from plants of the female parent, ‘Florida Sweetheart’, in the following characteristics:
    • 1. Plants of the new Caladium and ‘Florida Sweetheart’ differ in leaf color as leaves of the new Caladium are light red to variable shades of pink in color with random green and orange-colored spots with dark bronze red-colored venation and margins whereas leaves of ‘Florida Sweetheart’ have dark pink-colored venation, rose pink-colored interveinal areas with greenish white-colored margins.
    • 2. Plants of the new Caladium and ‘Florida Sweetheart’ differ in leaf petiole color as leaf petioles of the new Caladium are black or black with tannish pink stripes in color whereas leaf petioles of ‘Florida Sweetheart’ are tannish pink in color with darker-colored stripes.
Plants of the new Caladium differ primarily from plants of the male parent, ‘Scarlet Flame’, in the following characteristics:
    • 1. Plants of the new Caladium are taller than plants of ‘Scarlet Flame’.
    • 2. Plants of the new Caladium and ‘Scarlet Flame’ differ in leaf color as leaves of the new Caladium are light red to variable shades of pink in color with random green and orange-colored spots with dark bronze red-colored venation and margins whereas leaves of ‘Scarlet Flame’ are dark green in color with rose red-colored venation and pink and rose red-colored spots and blotches.
    • 3. Plants of the new Caladium and ‘Scarlet Flame’ differ in leaf petiole color as leaf petioles of the new Caladium are black or black with tannish pink stripes in color whereas leaf petioles of ‘Scarlet Flame’ are tannish green in color with black-colored streaks.
Plants of the new Caladium can be compared to plants of Caladium X hortulanum ‘Caribbean Coral’, disclosed in U.S. Plant Pat. No. 29,546. In side-by-side comparisons, plants of the new Caladium differ primarily from plants of ‘Caribbean Coral’ in the following characteristics:
    • 1. Plants of the new Caladium and ‘Caribbean Coral’ differ in leaf color as leaves of the new Caladium are light red to variable shades of pink in color with random green and orange-colored spots with dark bronze red-colored venation and margins whereas leaves of ‘Caribbean Coral’ are dark olive green in color with dark pink-colored venation surrounded with lighter pink areas and interveinal areas that are pink variably suffused with green in color with random greenish white and pink-colored spots.
    • 2. Plants of the new Caladium and ‘Caribbean Coral’ differ in leaf petiole color as leaf petioles of the new Caladium are black or black with tannish pink stripes in color whereas leaf petioles of ‘Caribbean Coral’ are tannish pink in color tinged with a brownish green-colored cast.
Plants of the new Caladium can also be compared to plants of Caladium X hortulanum ‘Blushing Bride’, disclosed in U.S. Plant Pat. No. 22,213. In side-by-side comparisons, plants of the new Caladium differ primarily from plants of ‘Blushing Bride’ in the following characteristics:
    • 1. Plants of the new Caladium and ‘Blushing Bride’ differ in leaf color as leaves of the new Caladium are light red to variable shades of pink in color with random green and orange-colored spots with dark bronze red-colored venation and margins whereas leaves of ‘Blushing Bride’ are greyed purple in color with dark green-colored margins and whitish-colored venation tinged with greyed purple.
    • 2. Plants of the new Caladium and ‘Blushing Bride’ differ in leaf petiole color as leaf petioles of the new Caladium are black or black with tannish pink stripes in color whereas leaf petioles of ‘Blushing Bride’ are tannish pink to tannish green in color with dark brownish green-colored stippling, streaks and tessellations.

 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 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 10,000 to 12,000 foot-candles. Plants grown in the shade house were five 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, 2015 Edition, except where general terms of ordinary dictionary significance are used.
