Description

Botanical designation: Caladium X hortulanum.
Cultivar denomination: ‘RIB OF15-809 RD’.
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 lance leaf-type Caladium and hereinafter referred to by the name ‘RIB OF15-809 RD’.
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, 2014 in Avon Park, Fla. of Caladium X hortulanum ‘Florida Red Ruffles’, disclosed in U.S. Plant Pat. No. 13,136, as the female, or seed, parent with Caladium X hortulanum ‘Red Frill’, 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 Avon Park, Fla. in September, 2015.
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, 2016 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 ‘RIB OF15-809 RD’. These characteristics in combination distinguish ‘RIB OF15-809 RD’ as a new and distinct Caladium plant:
    • 1. Compact and upright to outwardly arching plant habit; dense and bushy appearance.
    • 2. Vigorous growth habit and rapid growth rate.
    • 3. Upright, narrow and undulate lance-type leaves that are dark red in color with dark green-colored margins.
    • 4. Petioles that are tannish pink in color with brown-colored stippling, streaks and tessellations.
    • 5. Good garden performance and tolerance to high light conditions.
Plants of the new Caladium differ primarily from plants of the female parent, ‘Florida Red Ruffles’, in the following characteristics:
    • 1. Plants of the new Caladium are more upright than and not as mounding as plants of ‘Florida Red Ruffles’.
    • 2. Leaves of plants of the new Caladium are more narrow and more undulate than leaves of plants of ‘Florida Red Ruffles’.
    • 3. Leaves of plants of the new Caladium are more upright than leaves of plants of ‘Florida Red Ruffles’.
    • 4. Leaf petioles of plants of the new Caladium are tannish pink in color with brown-colored stippling, streaks and tessellations whereas leaf petioles of plants of ‘Florida Red Ruffles’ are almost black in color with tannish pink-colored stripes.
Plants of the new Caladium differ primarily from plants of the male parent, ‘Red Frill’, in the following characteristics:
    • 1. Plants of the new Caladium are more upright than and not as mounding as plants of ‘Red Frill’.
    • 2. Leaves of plants of the new Caladium are more narrow and more undulate than leaves of plants of ‘Red Frill’.
    • 3. Leaves of plants of the new Caladium are more upright than leaves of plants of ‘Red Frill’.
Plants of the new Caladium can be compared to plants of Caladium X hortulanum ‘Heart's Delight’, disclosed in U.S. Plant Pat. No. 23,992. In side-by-side comparisons, plants of the new Caladium differ primarily from plants of ‘Heart's Delight’ in the following characteristics:
    • 1. Plants of the new Caladium are more compact and upright than and not as mounding as plants of ‘Heart's Delight’.
    • 2. Leaves of plants of the new Caladium are more narrow and more undulate than leaves of plants of ‘Heart's Delight’.
    • 3. Leaves of plants of the new Caladium are more upright than leaves of plants of ‘Heart's Delight’.
    • 4. Leaves of plants of the new Caladium are dark red in color with dark green-colored margins whereas leaves of plants of ‘Heart's Delight’ have red-colored venation, greyed purple-colored interveinal areas and mottled light and dark green-colored borders.
    • 5. Leaf petioles of plants of the new Caladium are tannish pink in color with brown-colored stippling, streaks and tessellations whereas leaf petioles of plants of ‘Heart's Delight’ are green in color tinged with pink and varying brown-colored streaks and stripes.
Plants of the new Caladium can also be compared to plants of Caladium X hortulanum ‘UF 4424’, disclosed in U.S. Plant Pat. No. 25,598. In side-by-side comparisons, plants of the new Caladium differ primarily from plants of ‘UF 4424’ in the following characteristics:
    • 1. Plants of the new Caladium are more upright than and not as mounding as plants of ‘UF 4424’.
    • 2. Leaves of plants of the new Caladium are more narrow and more undulate than leaves of plants of ‘UF 4424’.
    • 3. Leaves of plants of the new Caladium are more upright than leaves of plants of ‘UF 4424’.
    • 4. Leaf petioles of plants of the new Caladium are tannish pink in color with brown-colored stippling, streaks and tessellations whereas leaf petioles of plants of ‘UF 4424’ are greyed red in color.

 DETAILED BOTANICAL DESCRIPTION
The aforementioned photographs and following observations and measurements describe plants grown in 25-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 23° C. to 26° 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 28° C. to 33° C. and under full sunlight conditions. Plants grown in the shade house were nine weeks old and plants grown in the outdoor nursery were six months old when the photographs and the detailed description were taken. Plants used in the photographs and detailed description did not have their tubers de-eyed. 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.
