plant named ‘Freckles’

Abstract

A new and distinct cultivar of Caladium plant named ‘Freckles’, characterized by its compact, intermediate height, upright and uniformly mounded plant habit; vigorous growth habit and very rapid growth rate; fancy type leaves that are dark green in color with orange and pink-colored spots and blotches; tolerance to full sun conditions; and above average tolerance to Xanthomonas Leaf Spot.

Description

Botanical designation: Caladium×hortulanum.

Cultivar denomination: ‘FRECKLES’.

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 ‘Freckles’.

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, 2007 in Avon Park, Fla. of Caladium×hortulanum ‘Twist N' Shout’, not patented, as the female, or seed, parent with Caladium×hortulanum ‘Red Flash’, 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 with 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 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 ‘Freckles’. These characteristics in combination distinguish ‘Freckles’ as a new and distinct Caladium plant:

• • 1. Compact, intermediate height, upright and uniformly mounded plant habit.
  • 2. Vigorous growth habit and very rapid growth rate.
  • 3. Fancy type leaves that are dark green in color with orange and pink-colored spots and blotches.
  • 4. Tolerant to full sun conditions.
  • 5. Above average tolerance to Xanthomonas Leaf Spot.

Plants of the new Caladium differ primarily from plants of the female parent, ‘Twist N' Shout’, in the following characteristics:

• • 1. Plants of the new Caladium have ovate-shaped leaves whereas leaves of ‘Twist N' Shout’ have hastate-shaped leaves.
  • 2. Leaves of plants of the new Caladium are smoother and flatter than leaves of ‘Twist N' Shout’.
  • 3. Plants of the new Caladium and ‘Twist N' Shout’ differ in leaf color as leaves of ‘Twist N' Shout’ are olive green in color with green to coppery bronze-colored venation and coppery orange-colored spots and blotches.

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

• • 1. Plants of the new Caladium are shorter than plants of ‘Red Flash’.
  • 2. Plants of the new Caladium are less apically dominant and are denser than plants of ‘Red Flash’.
  • 3. Plants of the new Caladium and ‘Red Flash’ differ in leaf color as leaves of ‘Red Flash’ have red-colored venation and interveinal areas with pink and white-colored spots and dark green-colored borders.
  • 4. Plants of the new Caladium and ‘Red Flash’ differ in leaf petiole color as leaf petioles of ‘Red Flash’ are reddish pink to tan pink in color with darker-colored stippling, stripes and tessellations.

Plants of the new Caladium can be compared to plants of Caladium×hortulanum ‘Creamsickle’, disclosed in U.S. Plant Pat. No. 23,991. In side-by-side comparisons, plants of the new Caladium differ primarily from plants of ‘Creamsickle’ in leaf color as leaves of ‘Creamsickle’ have greyed green-colored centers and venation with greyed green and greyed purple-colored interveinal areas interspersed with dark green-colored sectors and surrounded by dark green-colored borders. In addition, plants of the new Caladium are shorter than plants of ‘Creamsickle’.

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

• • 1. Plants of the new Caladium are shorter than plants of ‘Frieda Hemple’.
  • 2. Plants of the new Caladium and ‘Frieda Hemple’ differ in leaf color as leaves of ‘Frieda Hemple’ are medium green in color with bright red-colored centers and venation.
  • 3. Plants of the new Caladium and ‘Frieda Hemple’ differ in leaf petiole color as leaf petioles of ‘Frieda Hemple’ are dark brownish green, close to black, in color.

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 about 10,000 to 12,000 foot-candles. Plants grown in the shadehouse were seven weeks old (vegetative plant photographs and description) and nine weeks old (inflorescence photograph and description), and plants grown in the outdoor nursery were eight months old when the photographs and the detailed description were taken.
