Abstract

A new and distinct cultivar of Caladium plant named ‘Debutante’, characterized by its compact, upright and uniformly mounding plant habit; vigorous growth habit and rapid growth rate; lance-type leaves with white-colored background variably tinged with pink and with distinct dark green-colored venation and red purple-colored leaf notch; and good landscape performance.

Description

Botanical designation: Caladium×hortulanum.
Cultivar denomination: ‘DEBUTANTE’.
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 ‘Debutante’.
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, 2008 in Avon Park, Fla. of Caladium×hortulanum ‘White Wonder’, disclosed in U.S. Plant Pat. No. 21,044, as the female, or seed, parent with Caladium×hortulanum ‘Florida Sweetheart’, disclosed in U.S. Plant Pat. No. 8,526, 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. in September, 2009.
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 Lake Placid, Fla. since April, 2010 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 ‘Debutante’. These characteristics in combination distinguish ‘Debutante’ 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 with white-colored background variably tinged with pink and with distinct dark green-colored venation and red purple-colored leaf notch.
    • 4. Good landscape performance.
Plants of the new Caladium differ primarily from plants of the female parent, ‘White Wonder’, in leaf color as plants of ‘White Wonder’ have leaves with white-colored background blushed with pink and distinct dark green-colored margins. In addition, plants of the new Caladium grow faster and produce finished plants one to two weeks earlier than plants of ‘White Wonder’.
Plants of the new Caladium differ primarily from plants of the male parent, ‘Florida Sweetheart’, in leaf color as plants of ‘Florida Sweetheart’ have leaves with rose red-colored centers with distinct dark green-colored margins.
Plants of the new Caladium can be compared to plants of Caladium×hortulanum ‘Candidum’, not patented. In side-by-side comparisons, plants of the new Caladium differed primarily from plants of ‘Candidum’ in the following characteristics:
    • 1. Plants of the new Caladium were more compact and mounding than plants of ‘Candidum’.
    • 2. Leaves of plants of the new Caladium were lance-type whereas leaves of ‘Candidum’ were fancy-type.
    • 3. Plants of the new Caladium and ‘Candidum’ differed in leaf coloration as plants of ‘Candidum’ had white-colored leaves with dark green-colored venation.
Plants of the new Caladium can be compared to plants of Caladium×hortulanum ‘White Delight’, disclosed in U.S. Plant Pat. No. 21,216. In side-by-side comparisons, plants of the new Caladium differed primarily from plants of ‘White Delight’ in the following characteristics:
    • 1. Plants of the new Caladium were more compact and mounding than plants of ‘White Delight’.
    • 2. Plants of the new Caladium grew faster and produced finished plants about one to two weeks earlier than plants of ‘White Delight’.
    • 3. Plants of the new Caladium had broader leaves than plants of ‘White Delight’.
    • 4. Plants of the new Caladium and ‘White Delight’ differed in leaf coloration as leaves of plants of ‘White Delight’ were white to grey-green in color with white-colored main veins and green-colored or speckled margins.
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. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Caladium plant.

 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.
