Abstract

A new and distinct cultivar of Caladium plant named ‘Chinook’, characterized by its compact, upright and uniformly mounding plant habit; vigorous growth habit and very rapid growth rate; lance-type leaves that are medium green in color flushed with salmon pink and dark pink-colored venation; and good landscape performance.

Description

Botanical designation: Caladium×hortulanum.
Cultivar denomination: ‘CHINOOK’.
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 ‘Chinook’.
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, 2008 in Avon Park, Fla. of Caladium×hortulanum ‘White Wonder’, disclosed in U.S. Plant Pat. No. 21,044, as the female, or seed, parent with Caladium×hortulanum ‘Kathleen’, 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, 2009.
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 March, 2010 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 ‘Chinook’. These characteristics in combination distinguish ‘Chinook’ as a new and distinct Caladium plant:
    • 1. Compact, upright and uniformly mounding plant habit.
    • 2. Vigorous growth habit and very rapid growth rate.
    • 3. Lance-type leaves that are medium green in color flushed with salmon pink and dark pink-colored venation.
    • 4. Good landscape performance.
Plants of the new Caladium differ primarily from plants of the female parent, ‘White Wonder’, in the following characteristics:
    • 1. Plants of the new Caladium are more mounding than and not as upright as plants of ‘White Wonder’.
    • 2. Plants of the new Caladium are faster growing and produce finished plants about two to three weeks earlier than plants of ‘White Wonder’.
    • 3. Plants of the new Caladium and ‘White Wonder’ differ in leaf color as leaves of plants of ‘White Wonder’ are white to light pink in color with light pink to white-colored venation and dark green-colored margins.
Plants of the new Caladium differ primarily from plants of the male parent, ‘Kathleen’, in the following characteristics:
    • 1. Plants of the new Caladium are more compact than plants of ‘Kathleen’.
    • 2. Plants of the new Caladium are more mounding than and not as upright as plants of ‘Kathleen’.
    • 3. Plants of the new Caladium and ‘Kathleen’ differ in leaf shape and color as leaves of plants of ‘Kathleen’ are fancy-types and medium green in color with salmon pink-colored centers and light pink-colored venation.
Plants of the new Caladium can be compared to plants of Caladium×hortulanum ‘Florida Sweetheart’, disclosed in U.S. Plant Pat. No. 8,526. In side-by-side comparisons, plants of the new Caladium differed primarily from plants of ‘Florida Sweetheart’ in the following characteristics:
    • 1. Plants of the new Caladium were faster growing and produce finished plants about one week earlier than plants of ‘Florida Sweetheart’.
    • 2. Plants of the new Caladium and ‘Florida Sweetheart’ differed in leaf shape and color as leaves of plants of ‘Florida Sweetheart’ were broadly ovate in shape and pink in color with medium green to white-colored margins.
Plants of the new Caladium can also be compared to plants of Caladium×hortulanum ‘Blushing Bride’, disclosed in U.S. Plant Pat. No. 22,213. In side-by-side comparisons, plants of the new Caladium differed primarily from plants of ‘Blushing Bride’ in the following characteristics:
    • 1. Plants of the new Caladium were faster growing and produce finished plants about one week earlier than plants of ‘Blushing Bride’.
    • 2. Plants of the new Caladium and ‘Blushing Bride’ differed in leaf color as leaves of plants of ‘Blushing Bride’ were pink in color with narrow medium green-colored margins.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying photographs illustrate the overall appearance of the new Caladium plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Caladium plant.
The photograph on the first sheet is a side perspective view of a typical plant of ‘Chinook’ in a container and grown in a shadehouse (tuber not de-eyed).
The photograph at the top of the second sheet is a comparison view of typical potted plants of the female parent, ‘White Wonder’ (left), ‘Chinook’ (center) and the male parent, ‘Kathleen’ (right).
The photograph at the bottom of the second sheet is a comparison view of typical potted plants of ‘Florida Sweetheart’ (left), ‘Chinook’ (center) and ‘Blushing Bride’ (right).
The photograph at the top of the third sheet is a comparison view of typical plants of ‘Chinook’ grown in containers; the plant on the right has not had its tuber de-eyed and the plant on the left has had its tuber de-eyed prior to planting.
The photograph at the bottom of the third sheet is a side perspective view of typical plants of ‘Chinook’ grown in an open field.
The photograph at the top of the fourth sheet is a close-up view of typical freshly-harvested tubers and roots of ‘Chinook’ plants.
The photograph at the bottom of the fourth sheet is a close-up view of typical inflorescences of ‘Chinook’.
 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 four weeks old, and plants grown in the outdoor nursery were eight 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.
