Abstract

A new and distinct cultivar of Caladium plant named ‘White Wonder’, characterized by its intermediate plant habit; vigorous and dense growth habit; rapid growth rate; and strap-type leaves that are white to grey-green in color with light pink to white-colored veins and dark green-colored borders.

Description

Botanical designation: Caladium×hortulanum.
Cultivar denomination: ‘WHITE WONDER’.
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 strap leaf-type Caladium and hereinafter referred to by the name ‘White Wonder’.
The objective of the Inventor's breeding program is to create new Caladium cultivars that have uniform plant habit, exceptional performance and attractive foliage coloration.
The new Caladium plant originated from a self-pollination made by the Inventor in April, 2002, in Lake Placid, Fla. of Caladium×hortulanum ‘White Wing’, not patented. The new Caladium plant was discovered and selected by the Inventor as a single plant within the progeny of the stated self-pollination in a controlled outdoor nursery environment in Lake Placid, Fla. on Jun. 15, 2003.
Asexual reproduction of the new Caladium plant by tuber divisions in a controlled outdoor nursery environment in Lake Placid, Fla. since Apr. 15, 2004 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. The phenotype may vary somewhat with variations in environment 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 Wonder’. These characteristics in combination distinguish ‘White Wonder’ as a new and distinct cultivar of Caladium:
    • 1. Intermediate plant habit.
    • 2. Vigorous and dense growth habit; rapid growth rate.
    • 3. Strap-type leaves that are white to grey-green in color with light pink to white-colored veins and dark green-colored borders.
Plants of the new Caladium differ from plants of the parent, ‘White Wing’, in the following characteristics:
    • 1. Plants of the new Caladium are more compact and denser than plants of ‘White Wing’.
    • 2. Plants of the new Caladium grow faster than plants of ‘White Wing’.
    • 3. Leaves of plants of the new Caladium are more rounded than and not as pointed as leaves of plants of ‘White Wing’.
    • 4. Plants of the new Caladium and ‘White Wing’ differ in leaf coloration as plants of ‘White Wing’ have white-colored leaves with a mottled dark and light green-colored borders.
Plants of the new Caladium can be compared to plants of ‘Candidum Junior’, not patented. In side-by-side comparisons conducted in Lake Placid, Fla., plants of the new Caladium differed primarily from plants of ‘Candidum Junior’ in the following characteristics:
    • 1. Plants of the new Caladium had strap-type leaves whereas plants of ‘Candidum Junior’ had fancy-type leaves.
    • 2. Plants of the new Caladium and ‘Candidum Junior’ differed in leaf coloration as plants of ‘Candidum Junior’ had white-colored leaves with green-colored venation and narrow green-colored borders.
Plants of the new Caladium can be compared to plants of ‘Florida White Ruffles’, disclosed in U.S. Plant Pat. No. 14,402. In side-by-side comparisons conducted in Lake Placid, Fla., plants of the new Caladium differed primarily from plants of ‘Florida White Ruffles’ in the following characteristics:
    • 1. Plants of the new Caladium were more upright than plants of ‘Florida White Ruffles’.
    • 2. Plants of the new Caladium and ‘Florida White Ruffles’ differed in leaf coloration as plants of ‘Florida White Ruffles’ had creamy white-colored leaves with creamy white-colored venation and green-colored borders.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying photographs illustrate the overall appearance of the new Caladium. These photographs show 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.
The photograph on the first sheet is a side perspective view of a typical plant of ‘White Wonder’ grown in a container in a shadehouse.
The photograph at the top of the second sheet is a side perspective view of typical plants of ‘White Wonder’ (top center), ‘Candidum Junior’ (left) and ‘Florida White Ruffles’ (right) grown in a shadehouse.
The photograph at the bottom of the second sheet is a side perspective view of typical plants of ‘White Wing’ (left) and ‘White Wonder’ (right) grown in a shadehouse.
The photograph at the top of the third sheet is a top perspective view of typical plants of ‘White Wonder’ grown in an outdoor nursery.
The photograph at the bottom of the third sheet is a close-up view of typical freshly-dug tubers and roots of ‘White Wonder’.
The photograph on the fourth sheet is a close-up view of a typical inflorescence of ‘White Wonder’.
 DETAILED BOTANICAL DESCRIPTION
The aforementioned photographs and following observations and measurements describe plants grown in 15-cm containers in Avon Park, Fla. during the summer in a polypropylene-covered shadehouse and plants grown in ground beds in Zolfo Springs, Fla. during the late summer in an outdoor nursery. All plants were grown under conditions and practices which approximate those generally used in commercial Caladium production. During the production of the plants, day temperatures ranged from about 29° C. to 35° C., night temperatures ranged from about 22° C. to 26° C. and light levels were about 8,000 foot-candles (shadehouse) or 10,000 to 12,000 foot-candles (outdoor nursery). Plants had been growing in the shadehouse for five weeks from planting tubers when the photographs and the detailed description were taken. Plants had been growing in the outdoor nursery for seven months from planting tuber pieces 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.
