Abstract

A new and distinct cultivar of Caladium plant named ‘White Majesty’, characterized by its upright and uniformly mounding plant habit; vigorous growth habit and rapid growth rate; large and broad lance-type leaves that are medium green in color with white and greyed green-colored centers and venation; and good landscape performance.

Description

Botanical designation: Caladium×hortulanum.
Cultivar denomination: ‘WHITE MAJESTY’.
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 ‘White Majesty’.
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, 2006 in Avon Park, Fla. of a proprietary selection of Caladium×hortulanum identified as code number WS-02-18, not patented, as the female, or seed, parent with Caladium×hortulanum ‘Victoria’, disclosed in U.S. Plant Pat. No. 18,087, 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 September, 2007.
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, 2008 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 Majesty’. These characteristics in combination distinguish ‘White Majesty’ as a new and distinct Caladium plant:
    • 1. Upright and uniformly mounding plant habit.
    • 2. Vigorous growth habit and rapid growth rate.
    • 3. Large and broad lance-type leaves that are medium green in color with white and greyed green-colored centers and venation.
    • 4. Good landscape performance.
Plants of the new Caladium differ primarily from plants of the female parent selection in the following characteristics:
    • 1. Plants of the new Caladium are taller and more upright than plants of the female parent selection.
    • 2. Plants of the new Caladium and the female parent selection differ in leaf shape color as plants of the female parent selection have narrower leaves that are white and greyed white in color with a faint pink-colored blush and green-colored margins.
    • 3. Plants of the new Caladium and the female parent selection differ in leaf petiole color as plants of the female parent selection have green-colored leaf petioles with dark green-colored stippling and streaks.
Plants of the new Caladium differ primarily from plants of the male parent, ‘Victoria’, in the following characteristics:
    • 1. Plants of the new Caladium are taller and more upright than plants of ‘Victoria’.
    • 2. Plants of the new Caladium and ‘Victoria’ differ in leaf shape and coloration as plants of ‘Victoria’ have narrower undulate leaves that are greyed green in color and overlain with pink with rose red-colored venation and green-colored margins.
    • 3. Plants of the Caladium and ‘Victoria’ differ in leaf petiole coloration as leaf petioles of plants of ‘Victoria’ are tan pink in color with darker-colored stripes.
Plants of the new Caladium can be compared to plants of Caladium×hortulanum ‘White Star’, not patented. In side-by-side comparisons, plants of the new Caladium differed primarily from plants of ‘White Star’ in the following characteristics:
    • 1. Plants of the new Caladium were taller than plants of ‘White Star’.
    • 2. Plants of the new Caladium grew slower than plants of ‘White Star’ as plants of the new Caladium produced finished plants about one to two weeks later than plants of ‘White Star’.
    • 3. Plants of the new Caladium and ‘White Star’ differed in leaf shape and coloration as leaves of plants of ‘White Star’ were narrower, more undulate and green in color with white to grey green-colored centers, pink to light pink-colored venation and dark green-colored margins.
    • 4. Plants of the new Caladium and ‘White Star’ differed in leaf petiole coloration as leaf petioles of plants of ‘White Star’ were tan pink with darker-colored stippling.
Plants of the new Caladium can be compared to plants of Caladium×hortulanum ‘White Wing’, not patented. In side-by-side comparisons, plants of the new Caladium differed primarily from plants of ‘White Wing’ in the following characteristics:
    • 1. Plants of the new Caladium and ‘White Wing’ differed in leaf shape and coloration as plants of ‘White Wing’ had narrower undulate leaves that were dark green in color with creamy white-colored centers and variably mottled margins.
    • 2. Plants of the new Caladium and ‘White Wing’ differed in leaf petiole coloration as leaf petioles of plants of ‘White Wing’ were tan pink to green in color with darker-colored stippling.
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.
The photograph on the first sheet is a side perspective view of a typical plant of ‘White Majesty’ in a 15-cm container and grown in a shadehouse.
The photograph at the top of the second sheet is a view of typical plants of ‘White Majesty’ grown in an open field.
The photograph at the bottom of the second sheet is a close-up view of typical freshly-harvested tubers and roots of ‘White Majesty’.
The photograph at the top of the third sheet is a comparison view of typical potted plants of the female parent selection (left), ‘White Majesty’ (center) and the male parent, ‘Victoria’ (right).

 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.
