Abstract

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

Description

Botanical designation: Caladium×hortulanum.
Cultivar denomination: ‘WHITE CAP’.
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 ‘White Cap’.
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 in April, 2007 in Avon Park, Fla. of Caladium×hortulanum ‘White Christmas’, not patented, as the female, or seed, parent with Caladium×hortulanum ‘Aaron’, 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. in September, 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 Zolfo Springs, Fla. since April, 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 ‘White Cap’. These characteristics in combination distinguish ‘White Cap’ 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 white-colored venation and white, greyed green and green speckled interveinal areas and dark green-colored margins.
    • 5. Good landscape performance.
Plants of the new Caladium differ primarily from plants of the female parent, ‘White Christmas’, in the following characteristics:
    • 1. Plants of the new Caladium and ‘White Christmas’ differ in leaf petiole color.
    • 2. Plants of the new Caladium and ‘White Christmas’ differ 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 differ primarily from plants of the male parent, ‘Aaron’, in the following characteristics:
    • 1. Plants of the new Caladium grew faster than plants of ‘Aaron’.
    • 2. Plants of the new Caladium and ‘Aaron’ differ in leaf petiole color.
    • 3. Plants of the new Caladium and ‘Aaron’ differ in leaf coloration as leaves of plants of ‘Aaron’ have white-colored venation and radiating interveinal areas surrounded with green-colored borders.
Plants of the new Caladium can be compared to plants of Caladium ‘Florida Blizzard’, disclosed in U.S. Plant Pat. No. 14,406. In side-by-side comparisons conducted in Avon Park, Fla., plants of the new Caladium differed primarily from plants of ‘Florida Blizzard’ in the following characteristics:
    • 1. Plants of the new Caladium and ‘Florida Blizzard’ differed in leaf petiole color.
    • 2. Plants of the new Caladium and ‘Florida Blizzard’ differed in leaf coloration as leaves of plants of ‘Florida Blizzard’ had greyed green-colored venation, white-colored interveinal areas with a red purple-colored leaf petiole/leaf junction and dark green-colored borders and margins.
Plants of the new Caladium can also 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. Plants of the new Caladium and ‘Candidum’ differed in leaf petiole color.
    • 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 and 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 during the spring in 15-cm containers in Avon Park, Fla. in a polypropylene-covered shadehouse (30% shade) and plants grown during the autumn in ground beds in an outdoor nursery in Zolfo Springs, Fla. 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 28° 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.
