Abstract

A new and distinct cultivar of Caladium plant named ‘Peppermint’, characterized by its upright and mounding plant habit; intermediate plant size; vigorous and dense growth habit; rapid growth rate; lance-type leaves that are red purple and white in color with dark green-colored margins and white-colored venation.

Description

Botanical designation: Caladium×hortulanum.
Cultivar denomination: ‘PEPPERMINT’.
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 lance leaf-type Caladium and hereinafter referred to by the name ‘Peppermint’.
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 April, 2002, in Lake Placid, Fla. of Caladium×hortulanum ‘Pink Symphony’, not patented, as the female, or seed, parent with Caladium×hortulanum ‘White Wing’, 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 tuber divisions 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. 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 ‘Peppermint’. These characteristics in combination distinguish ‘Peppermint’ as a new and distinct Caladium plant:
    • 1. Upright and mounding plant habit; intermediate plant size.
    • 2. Vigorous and dense growth habit; rapid growth rate.
    • 3. Lance-type leaves that are red purple and white in color with dark green-colored margins and white-colored venation.
Plants of the new Caladium differ primarily from plants of the female parent, ‘Pink Symphony’, in the following characteristics:
    • 1. Leaves of plants of the new Caladium are broader than leaves of plants of ‘Pink Symphony’.
    • 2. Plants of the new Caladium and ‘Pink Symphony’ differ in leaf coloration as plants of ‘Pink Symphony’ have light pink-colored leaves with green-colored margins and venation.
Plants of the new Caladium differ primarily from plants of the male parent, ‘White Wing’, in the following characteristics:
    • 1. Plants of the new Caladium had broader leaves than plants of ‘White Wing’.
    • 2. Plants of the new Caladium and ‘White Wing’ differ in leaf color as plants of ‘White Wing’ have white and green-colored leaves with green-colored mottled margins and pink to creamy white-colored venation.
Plants of the new Caladium can be compared to plants of ‘Florida Sweetheart’, disclosed in U.S. Plant Pat. No. 8,526. In side-by-side comparisons conducted in Lake Placid, Fla., plants of the new Caladium differed primarily from plants of ‘Florida Sweetheart’ in the following characteristics:
    • 1. Plants of the new Caladium were larger than plants of ‘Florida Sweetheart’.
    • 2. Plants of the new Caladium had narrower leaves than plants of ‘Florida Sweetheart’.
    • 3. Plants of the new Caladium and ‘Florida Sweetheart’ differed in leaf coloration as plants of ‘Florida Sweetheart’ had dark pink-colored leaves with thin green-colored margins and rose red-colored venation.
Plants of the new Caladium can also be compared to plants of ‘Thai Beauty’, not patented. In side-by-side comparisons conducted in Lake Placid, Fla., plants of the new Caladium differed primarily from plants of ‘Thai Beauty’ in the following characteristics:
    • 1. Plants of the new Caladium had broader leaves than plants of ‘Thai Beauty’.
    • 2. Plants of the new Caladium and ‘Thai Beauty’ differed in leaf coloration as plants of ‘Thai Beauty’ had pink-colored leaves with thin green-colored margins and white to greenish white-colored venation.

 DETAILED BOTANICAL DESCRIPTION
The aforementioned photographs and following observations and measurements describe plants grown during the spring and summer in 15-cm containers in Avon Park, Fla. in a polypropylene-covered shadehouse (30% shade) and plants grown during the spring and summer in ground beds in Zolfo Springs, Fla. during the late summer in an outdoor nursery. All plants were grown under conditions and practices which approximate those generally used in commercial Caladium production. During the production of the plants, day temperatures ranged from about 20° C. to 35° C., night temperatures ranged from about 10° C. to 26° C. and light levels were about 8,000 foot-candles (shadehouse) or 10,000 to 12,000 foot-candles (outdoor nursery). Plants had been growing in the shadehouse for eight weeks from planting tubers when the photographs and the detailed description were taken. Plants had been growing in the outdoor nursery for six months from planting tuber divisions 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.
