plant named ‘KAT 011-118’

Abstract

A new and distinct cultivar of Caladium plant named ‘KAT 011-118’, characterized by its intermediate height; upright and mounding plant habit; dense and bushy appearance; vigorous growth habit and rapid growth rate; fancy-type leaves that are dark green in color with bright red-colored centers and venation that resist fading; and petioles that are dark brown in color with greenish greyed orange-colored streaks and greenish brown stipples, streaks and tessellations.

Description

Botanical designation: Caladium X hortulanum.

Cultivar denomination: ‘KAT 011-118’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Caladium plant, botanically known as Caladium X hortulanum, commercially referred to as a fancy leaf-type Caladium and hereinafter referred to by the name ‘KAT 011-118’.

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, 2010 in Avon Park, Fla. of Caladium X hortulanum ‘Frieda Hemple’, not patented, as the female, or seed, parent with Caladium X hortulanum ‘White Wonder’, disclosed in U.S. Plant Pat. No. 21,044, 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, 2011.

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, 2012 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 combinations of 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 ‘KAT 011-118’. These characteristics in combination distinguish ‘KAT 011-118’ as a new and distinct Caladium plant:

• • 1. Intermediate in height and upright and mounding plant habit; dense and bushy appearance.
  • 2. Vigorous growth habit and rapid growth rate.
  • 3. Fancy-type leaves that are dark green in color with bright red-colored centers and venation that resist fading.
  • 4. Petioles that are dark brown in color with greenish greyed orange-colored streaks and greenish brown stipples, streaks and tessellations.

Plants of the new Caladium differ primarily from plants of the female parent, ‘Frieda Hemple’, in leaf color as leaves of the new Caladium are dark green in color with bright red-colored centers and venation whereas leaves of ‘Frieda Hemple’ are medium green in color with deep red-colored centers and venation.

Plants of the new Caladium differ primarily from plants of the male parent, ‘White Wonder’, in the following characteristics:

• • 1. Plants of the new Caladium have fancy-type leaves whereas plants of ‘White Wonder’ have lance-type leaves.
  • 2. Plants of the new Caladium and ‘White Wonder’ differ in leaf color as leaves of the new Caladium are dark green in color with bright red-colored centers and venation whereas leaves of ‘White Wonder’ are white to grey-green in color with light pink to white-colored venation and dark green-colored borders.
  • 3. Plants of the new Caladium and ‘White Wonder’ differ in leaf petiole color as petioles of the new Caladium are dark brown in color with greenish greyed orange-colored streaks and greenish brown stipples, streaks and tessellations whereas petioles of ‘White Wonder’ are greenish tan with darker-colored stripes.

Plants of the new Caladium can be compared to plants of Caladium X hortulanum ‘Kathleen’, not patented. In side-by-side comparisons, plants of the new Caladium differ primarily from plants of ‘Kathleen’ in the following characteristics:

• • 1. Plants of the new Caladium are shorter than plants of ‘Kathleen’.
  • 2. Plants of the new Caladium and ‘Kathleen’ differ in leaf color as leaves of the new Caladium are dark green in color with bright red-colored centers and venation whereas leaves of ‘Kathleen’ have medium green-colored margins and reddish pink-colored centers that fade to light pink with development.
  • 3. Plants of the new Caladium and ‘Kathleen’ differ in leaf petiole color as petioles of the new Caladium are dark brown in color with greenish greyed orange-colored streaks whereas petioles of ‘Kathleen’ are greenish tan tinged with pinkish tan in color with greenish brown-colored stipples, streaks and stripes.

Plants of the new Caladium can be compared to plants of Caladium X hortulanum ‘Rose Glow’, disclosed in U.S. Plant Pat. No. 20,070. In side-by-side comparisons, plants of the new Caladium differ primarily from plants of ‘Rose Glow’ in the following characteristics:

• • 1. Plants of the new Caladium and ‘Rose Glow’ differ in leaf color as leaves of the new Caladium are dark green in color with bright red-colored centers and venation whereas leaves of ‘Rose Glow’ are red purple in color with white-colored midveins, green-colored borders and dark green-colored margins.
  • 2. Plants of the new Caladium and ‘Rose Glow’ differ in leaf petiole color as petioles of the new Caladium are dark brown in color with greenish greyed orange-colored streaks whereas petioles of ‘Rose Glow’ are greenish tan in color with darker green-colored tessellations and speckles.

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 under full sunlight conditions 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 shadehouse-grown plants, day temperatures ranged from about 28° C. to 33° C., night temperatures ranged from about 22° C. to 25° C. and light levels were about 8,000 foot-candles. During the production of the outdoor nursery-grown plants, day temperatures ranged from about 29° C. to 35° C., night temperatures ranged from about 23° C. to 26° C. and light levels ranged from 10,000 to 12,000 foot-candles. Plants grown in the shadehouse were eight weeks old and plants grown in the outdoor nursery were six months old when the photographs and the detailed description were taken.
