Abstract: A new and distinct cultivar of Caladium plant named `Mt. Everest`, characterized by its upright and outwardly arching plant habit; vigorous growth habit; undulate strap-like leaves; and green and white-colored leaves with red purple-colored venation.
Claim: It is claimed:

1. A new and distinct Caladium plant named `Mt. Everest` as illustrated and described.
Description: Botanical designation:Caladium.times.hortulanum.

Cultivar denomination: `Mt. Everest`.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Caladium plant, botanically known as Caladium.times.hortulanum, commercially referred to as a strap-leaf Caladium and hereinafter referred to by the name `Mt. Everest`.

The new Caladium originated from a cross-pollination made by the Inventor in April, 2001, in Lake Placid, Fla. of the Caladium.times.hortulanum cultivar Grey Ghost, not patented, as the female, or seed, parent with the Caladium.times.hortulanumcultivar White Wing, not patented, as the male, or pollen, parent. The new Caladium was discovered and selected by the Inventor as a single plant within the progeny of the stated cross-pollination in a controlled environment in Lake Placid, Fla. onJun. 15, 2002.

Asexual reproduction of the new cultivar by tuber divisions in a controlled environment in Lake Placid, Fla. since Apr. 15, 2003 has shown that the unique features of this new Caladium are stable and reproduced true to type in successivegenerations of asexual reproduction.

SUMMARY OF THE INVENTION

The cultivar Mt. Everest has 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 `Mt. Everest`. These characteristics in combination distinguish `Mt. Everest` as a new and distinct cultivar of Caladium: 1. Upright andoutwardly arching plant habit. 2. Vigorous growth habit. 3. Undulate strap-like leaves. 4. Green and white-colored leaves with red purple-colored venation.

In side-by-side comparisons conducted in Lake Placid, Fla., plants of the new Caladium differed from plants of the female parent, the cultivar Grey Ghost, in the following characteristics: 1. Plants of the new Caladium were shorter than plantsof the cultivar Grey Ghost. 2. Leaves of plants of the new Caladium were strap-like whereas leaves of plants of the cultivar Grey Ghost were fancy types. 3. Leaves of plants of the new Caladium were more undulate than leaves of plants of the cultivarGrey Ghost. 4. Leaves of plants of the new Caladium were more rugose and more textured in appearance than leaves of plants of the cultivar Grey Ghost. 5. Plans of the new Caladium and the cultivar Grey Ghost differed in leaf coloration.

In side-by-side comparisons conducted in Lake Placid, Fla., plants of the new Caladium differed from plants of the male parent, the cultivar White Wing, in the following characteristics: 1. Under high light conditions, plants of the new Caladiumwere taller and more vigorous than plants of the cultivar White Wing. 2. Plants of the new Caladium and of the cultivar White Wing differed in leaf coloration as plants of the cultivar White Wing had creamy white and green leaves with pink towhite-colored venation.

Plants of the new Caladium can also be compared to plants of the cultivar Gingerland, not patented. In side-by-side comparisons conducted in Lake Placid, Fla., plants of the new Caladium differed from plants of the cultivar Gingerland in thefollowing characteristics: 1. Plants of the new Caladium were taller than plants of the cultivar Gingerland. 2. Plants of the new Caladium and the cultivar Gingerland differed in leaf coloration as plants of the cultivar Gingerland had red-spottedleaves with white-colored venation. 3. Plants of the Caladium had longer leaf petioles than plants of the cultivar Gingerland.
