Abstract

A new and distinct cultivar of Caladium plant named ‘Celebration’, characterized by its upright plant habit; intermediate to tall plant size; uniform plant habit; vigorous and dense growth habit; fancy-type leaves with dark red-colored venation, white-colored interveinal areas surrounded by dark green-colored borders; and good landscape performance.

Description

Botanical designation: Caladium×hortulanum.
Cultivar denomination: ‘CELEBRATION’.
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 fancy leaf-type Caladium and hereinafter referred to by the name ‘Celebration’.
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 foliage coloration.
The new Caladium plant originated from a cross-pollination made by the Inventor on Apr. 15, 2007, in Avon Park, Fla. of Caladium×hortulanum ‘John Peed’, not patented, as the female, or seed, parent with Caladium×hortulanum ‘White Christmas’, 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 Zolfo Springs, Fla. on Sep. 15, 2008.
Asexual reproduction of the new Caladium plant by ‘chipping’ the tubers (cutting the tuber into segments each segment containing an axillary bud and tuber cortical tissue) in a controlled outdoor nursery environment in Lake Placid, Fla. since Apr. 15, 2009 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 ‘Celebration’. These characteristics in combination distinguish ‘Celebration’ as a new and distinct Caladium plant:
    • 1. Upright plant habit; intermediate to tall plant size.
    • 2. Uniform plant habit.
    • 3. Vigorous and dense growth habit.
    • 4. Fancy-type leaves with dark red-colored venation, white-colored interveinal areas surrounded by dark green-colored borders.
    • 5. Good landscape performance and tolerant to full sun conditions.
Plants of the new Caladium differ primarily from plants of the female parent, ‘John Peed’, in the following characteristics:
    • 1. Plants of the new Caladium grow faster than plants of ‘John Peed’.
    • 2. Plants of the new Caladium and ‘John Peed’ differ in leaf coloration as leaves of plants of ‘John Peed’ have red-colored venation and interveinal areas surrounded by dark green-colored margins.
    • 3. Plants of the new Caladium and ‘John Peed’ differ in leaf petiole coloration as plants of ‘John Peed’ have dark red-colored leaf petioles.
Plants of the new Caladium differ primarily from plants of the male parent, ‘White Christmas’, in leaf coloration as leaves of plants of ‘White Christmas’ have dark green-colored venation, white-colored interveinal areas and dark green-colored borders.
Plants of the new Caladium can be compared to plants of Caladium ‘Candidum’, not patented. In side-by-side comparisons conducted in Avon Park, Fla., plants of the new Caladium differed primarily from plants of ‘Candidum’ in the following characteristics:
    • 1. Leaves of plants of the new Caladium were more undulate than leaves of plants of ‘Candidum’.
    • 2. Plants of the new Caladium and ‘Candidum’ differed in leaf coloration as leaves of plants of ‘Candidum’ had green-colored venation, variably white-colored interveinal areas and green-colored margins.
Plants of the new Caladium can also be compared to plants of ‘Tapestry’, not patented. In side-by-side comparisons conducted in Lake Placid, Fla., plants of the new Caladium differed primarily from plants of ‘Tapestry’ in the following characteristics:
    • 1. Plants of the new Caladium grew faster than plants of ‘Tapestry’.
    • 2. Plants of the new Caladium and ‘Tapestry’ differed in leaf coloration as leaves of plants of ‘Tapestry’ had rose pink-colored venation, white and pink-colored interveinal areas surrounded by olive green-colored borders.
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 during the spring in 15-cm containers in Avon Park, Fla. in a polypropylene-covered shadehouse (30% shade) and plants grown in ground beds in an outdoor nursery in Zolfo Springs, Fla. during the autumn. All plants were grown under environmental conditions and cultural practices which approximate those generally used in commercial shadehouse and outdoor nursery Caladium 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 seven weeks old when the photographs and the detailed description were taken. 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.
