Description

Botanical designation: Caladium X hortulanum.

Cultivar denomination: ‘CWH BRZ OF16-130’.

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. 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 fancy leaf-type Caladium and hereinafter referred to by the name ‘CWH BRZ OF16-130’.

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, 2015 in Avon Park, Fla. of Caladium X hortulanum ‘Southern Charm’, disclosed in U.S. Plant Pat. No. 27,942, 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, 2016.

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, 2017 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 ‘CWH BRZ OF16-130’.These characteristics in combination distinguish ‘CWH BRZ OF16-130’ as a new and distinct Caladium plant:

    • 1. Intermediate to tall and upright to mounding plant habit; dense, leafy and bushy appearance.
    • 2. Vigorous growth habit and rapid growth rate.
    • 3. Fancy-type leaves that are dark olive green overlain with reddish bronze in color with pale orangish pink-colored blotches and dark green-colored blotches flushed with reddish bronze, and bright reddish pink-colored areas surrounding the venation.
    • 4. Petioles that are reddish bronze in color.
    • 5. Tolerant to full sun conditions.

Plants of the new Caladium differ primarily from plants of the female parent, ‘Southern Charm’, in the following characteristics:

    • 1. Leaves of plants of the new Caladium are dark olive green overlain with reddish bronze in color with pale orangish pink-colored blotches and dark green-colored blotches flushed with reddish bronze, and bright reddish pink-colored areas surrounding the venation whereas leaves of plants of ‘Southern Charm’ are grey green in color with dark green-colored margins and red purple-colored venation and areas surrounding the venation.
    • 2. Leaf petioles of plants of the new Caladium are reddish bronze in color whereas leaf petioles of plants of ‘Southern Charm’ are green in color and tinged with pink.

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 have fancy-type leaves whereas plants of ‘Scarlet Flame’ have lance-type leaves.
    • 3. Leaves of plants of the new Caladium are dark olive green overlain with reddish bronze in color with pale orangish pink-colored blotches and dark green-colored blotches flushed with reddish bronze, and bright reddish pink-colored areas surrounding the venation whereas leaves of plants of ‘Scarlet Flame’ are dark green in color with rose red-colored venation and pink and rose red-colored spots and blotches.
    • 4. Leaf petioles of plants of the new Caladium are reddish bronze in color whereas leaf petioles of plants of ‘Scarlet Flame’ are dark green in color densely covered with dark brown-colored streaks and stippling appearing almost black in color.

Plants of the new Caladium can be compared to plants of Caladium X hortulanum ‘Carolyn Whorton’, not patented. In side-by-side comparisons, plants of the new Caladium differ primarily from plants of ‘Carolyn Whorton’ in the following characteristics:

    • 1. Leaves of plants of ‘Carolyn Whorton’ are flatter than and not as cupped as leaves of the new Caladium.
    • 2. Leaves of plants of the new Caladium are dark olive green overlain with reddish bronze in color with pale orangish pink-colored blotches and dark green-colored blotches flushed with reddish bronze, and bright reddish pink-colored areas surrounding the venation whereas leaves of plants of ‘Carolyn Whorton’ are olive green in color with pink-colored blotches and bright red to rose pink-colored venation.
    • 3. Leaf petioles of plants of the new Caladium are reddish bronze in color whereas leaf petioles of plants of ‘Carolyn Whorton’ are tannish pink and tannish green in color with darker-colored streaks, stippling and tessellations.

Plants of the new Caladium can also be compared to plants of Caladium X hortulanum ‘Xplosion’, disclosed in U.S. Plant Pat. No. 31,570. In side-by-side comparisons, plants of the new Caladium differ primarily from plants of ‘Xplosion’ in the following characteristics:

    • 1. Plants of the new Caladium have fancy-type leaves whereas plants of ‘Xplosion’ have lance-type leaves.
    • 2. Leaves of plants of ‘Xplosion’ are flatter than and not as cupped as leaves of the new Caladium.
    • 3. Leaves of plants of the new Caladium are dark olive green overlain with reddish bronze in color with pale orangish pink-colored blotches and dark green-colored blotches flushed with reddish bronze, and bright reddish pink-colored areas surrounding the venation whereas leaves of plants of ‘Xplosion’ are dark green in color tinged with greyed purple with red purple to dark red-colored venation and interveinal areas that are white in color with light red-colored spots.
    • 4. Leaf petioles of plants of the new Caladium are reddish bronze in color whereas leaf petioles of plants of ‘Xplosion’ are greyed red, green and greyed green in color with dark brown-colored streaks and stipples.

 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 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 twelve weeks old and plants grown in the outdoor nursery were 4.5 to 6 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.
