Abstract

A new and distinct cultivar of Caladium plant named ‘Tickle Me Pink’, characterized by its intermediate height and upright and mounding plant habit; vigorous growth habit and rapid growth rate; lance-type leaves that have dark green-colored margins, rose red venation and interveinal areas that are green, tan green and rose red mosaic; petioles that are green or tan pink in color with darker-colored stippling and tessellations; and above average tolerance to wind.

Description

Botanical designation: Caladium X hortulanum.

Cultivar denomination: ‘TICKLE ME PINK’.

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 lance leaf-type Caladium and hereinafter referred to by the name ‘Tickle Me Pink’.

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 ‘Florida Sweetheart’, disclosed in U.S. Plant Pat. No. 8,526, 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 ‘Tickle Me Pink’. These characteristics in combination distinguish ‘Tickle Me Pink’ as a new and distinct Caladium plant:

    • 1. Intermediate in height and upright and mounding plant habit.
    • 2. Vigorous growth habit and rapid growth rate.
    • 3. Lance-type leaves that have dark green-colored margins, rose red venation and interveinal areas that are green, tan green and rose red mosaic.
    • 4. Petioles that are green or tan pink in color with darker-colored stippling and tessellations.
    • 5. Above average tolerance to wind.

Plants of the new Caladium differ primarily from plants of the female parent, ‘Florida Sweetheart’, in the following characteristics:

    • 1. Plants of the new Caladium are taller than plants of ‘Florida Sweetheart’.
    • 2. Plants of the new Caladium grow faster and finish about two weeks earlier than plants of ‘Florida Sweetheart’.
    • 3. Plants of the new Caladium and ‘Florida Sweetheart’ differ in leaf color as leaves of ‘Florida Sweetheart’ have dark pink-colored venation, rose pink-colored interveinal areas with greenish white-colored margins.

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 are taller than plants of ‘White Wonder’.
    • 2. Plants of the new Caladium and ‘White Wonder’ differ in leaf color as 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 plants of ‘White Wonder’ have tan green-colored leaf petioles with darker-colored stripes.

Plants of the new Caladium can be compared to plants of Caladium X hortulanum ‘Puppy Love’, disclosed in U.S. Plant Pat. No. 25,424. In side-by-side comparisons, plants of the new Caladium differ primarily from plants of ‘Puppy Love’ in the following characteristics:

    • 1. Plants of the new Caladium grow faster and finish about one week earlier than plants of ‘Puppy Love’.
    • 2. Leaves of plants of the new Caladium are ovate in shape whereas leaves of plants of ‘Puppy Love’ are ovate to lanceolate in shape.
    • 3. Plants of the new Caladium and ‘Puppy Love’ differ in leaf color as leaves of ‘Puppy Love’ are rose red in color with rose red-colored venation and green to whitish green-colored margins.

Plants of the new Caladium can be compared to plants of Caladium X hortulanum ‘Blushing Bride’, disclosed in U.S. Plant Pat. No. 22,213. In side-by-side comparisons, plants of the new Caladium differ primarily from plants of ‘Blushing Bride’ in the following characteristics:

    • 1. Plants of the new Caladium are taller than plants of ‘Blushing Bride’.
    • 2. Plants of the new Caladium grow faster and finish about one week earlier than plants of ‘Blushing Bride’.
    • 3. Plants of the new Caladium and ‘Blushing Bride’ differ in leaf color as leaves of ‘Blushing Bride’ are greyed purple-colored leaves with dark green-colored margins and whitish-colored venation tinged with greyed purple.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown in 15-cm containers in a polypropylene-covered shadehouse (50% 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 were about 10,000 to 12,000 foot-candles. Plants grown in the shadehouse were eight weeks old and plants grown in the outdoor nursery were 7.5 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.
