Abstract

A new and distinct cultivar of Caladium plant named ‘Sweet Carolina’, characterized by its upright plant habit; tall plant size; uniform plant habit; vigorous and dense growth habit; fancy-type leaves with greyed purple-colored venation, random red purple-colored spots and mottled light and dark green-colored interveinal areas; and good landscape performance.

Description

Botanical designation: Caladium×hortulanum.
Cultivar denomination: ‘SWEET CAROLINA’.
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 ‘Sweet Carolina’.
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 foliage coloration.
The new Caladium plant originated from a cross-pollination made by the Inventor in June, 2002 in Lake Placid, Fla. of Caladium×hortulanum ‘Grey Ghost’, not patented, as the female, or seed, parent with Caladium×hortulanum ‘Miss Muffet’, 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 Lake Placid, Fla. on Jun. 15, 2003.
Asexual reproduction of the new Caladium plant by ‘chipping’ the tubers (cutting the tuber into segments each segment containing an axillary bud and tuber cortical tissue) in a controlled outdoor nursery environment in Lake Placid, Fla. since Apr. 15, 2004 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 ‘Sweet Carolina’. These characteristics in combination distinguish ‘Sweet Carolina’ as a new and distinct Caladium plant:
    • 1. Upright plant habit; tall plant size.
    • 2. Uniform plant habit.
    • 3. Vigorous and dense growth habit.
    • 4. Fancy-type leaves with greyed purple-colored venation, random red purple-colored spots and mottled light and dark green-colored interveinal areas.
    • 5. Good landscape performance and tolerant to full sun conditions.
Plants of the new Caladium differ primarily from plants of the female parent, ‘Grey Ghost’, in the following characteristics:
    • 1. Plants of the new Caladium are taller than plants of ‘Grey Ghost’.
    • 2. Plants of the new Caladium and ‘Grey Ghost’ differ in leaf coloration as leaves of plants of ‘Grey Ghost’ have white to grey white-colored venation and interveinal areas with green-colored borders.
Plants of the new Caladium differ primarily from plants of the male parent, ‘Miss Muffet’, in the following characteristics:
    • 1. Plants of the new Caladium are taller than plants of ‘Miss Muffet’.
    • 2. Leaves of plants of the new Caladium are broader than leaves of plants of ‘Miss Muffet’.
    • 3. Plants of the new Caladium and ‘Miss Muffet’ differ in leaf coloration as leaves of plants of ‘Miss Muffet’ have red-colored venation, lime green interveinal areas and red-colored spots.
Plants of the new Caladium can be compared to plants of Caladium ‘Raspberry Moon’, disclosed in U.S. Plant Pat. No. 20,069. In side-by-side comparisons conducted in Avon Park, Fla., plants of the new Caladium differed primarily from plants of ‘Raspberry Moon’ in the following characteristics:
    • 1. Plants of the new Caladium were taller and more vigorous than plants of ‘Raspberry Moon’.
    • 2. Leaves of plants of the new Caladium were more rounded than and not as undulate as leaves of plants of ‘Raspberry Moon’.
    • 3. Plants of the new Caladium and ‘Raspberry Moon’ differed in leaf coloration as leaves of plants of ‘Raspberry Moon’ were light green in color with random dark green and red-colored spots and splotches.
Plants of the new Caladium can also be compared to plants of Caladium ‘Aaron’, not patented. In side-by-side comparisons conducted in Avon Park, Fla., plants of the new Caladium differed primarily from plants of ‘Aaron’ in the following characteristics:
    • 1. Plants of the new Caladium were taller than plants of ‘Aaron’.
    • 2. Plants of the new Caladium grew faster than plants of ‘Aaron’.
    • 3. Plants of the new Caladium and ‘Aaron’ differed in leaf coloration as leaves of plants of ‘Aaron’ have white-colored venation and radiating interveinal areas surrounded with green-colored borders.

 DETAILED BOTANICAL DESCRIPTION
The aforementioned photographs and following observations and measurements describe plants grown during the spring in 15-cm containers in Avon Park, Fla. in a polypropylene-covered shadehouse (30% shade) and plants grown during the summer in ground beds in an outdoor nursery in Zolfo Springs, Fla. All plants were grown under environmental conditions and cultural practices which approximate those generally used in commercial shadehouse and outdoor nursery Caladium production. During the production of the plants, day temperatures ranged from about 28° 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 seven weeks old when the photographs and the detailed description were taken. Plants grown in the outdoor nursery were six 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.
