Abstract

A new and distinct cultivar of Caladium plant named ‘Blushing Bride’, characterized by its upright and mounding plant habit; intermediate plant size; uniform potted plant habit; vigorous and dense growth habit; fast growth rate; and lance-type greyed purple-colored leaves with dark green-colored margins and whitish-colored venation tinged with greyed purple.

Description

Botanical designation: Caladium×hortulanum.
Cultivar denomination: ‘BLUSHING BRIDE’.
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 ‘Blushing Bride’.
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 ‘Aaron’, 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 ‘Blushing Bride’. These characteristics in combination distinguish ‘Blushing Bride’ as a new and distinct Caladium plant:
    • 1. Upright and mounding plant habit; intermediate plant size.
    • 2. Uniform potted plant habit.
    • 3. Vigorous and dense growth habit.
    • 4. Fast growth rate.
    • 5. Lance-type greyed purple-colored leaves with dark green-colored margins and whitish-colored venation tinged with greyed purple.
Plants of the new Caladium differ primarily from plants of the female parent, ‘Pink Symphony’, in the following characteristics:
    • 1. Plants of the new Caladium are more compact than and not as upright as plants of ‘Pink Symphony’.
    • 2. Plants of the new Caladium grow faster than plants of ‘Pink Symphony’.
    • 3. Plants of the new Caladium and ‘Pink Symphony’ differ in leaf coloration as plants of ‘Pink Symphony’ have light pink to white-colored leaves with green-colored margins and green-colored venation.
Plants of the new Caladium differ primarily from plants of the male parent, ‘Aaron’, in the following characteristics:
    • 1. Plants of the new Caladium are shorter than plants of ‘Aaron’.
    • 2. Plants of the new Caladium grow faster than plants of ‘Aaron’.
    • 3. Plants of the new Caladium and ‘Aaron’ differ in leaf coloration as plants of ‘Aaron’ have white-colored leaves with green-colored margins and 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 taller and more upright than plants of ‘Florida Sweetheart’.
    • 2. Leaves of plants of the new Caladium were more elongate than and not as broad as leaves of plants of ‘Florida Sweetheart’.
    • 3. Plants of the new Caladium and ‘Florida Sweetheart’ differed in leaf coloration as plants of ‘Florida Sweetheart’ had light pink-colored leaves with white and green-colored margins and rose-colored venation.
    • 4. Plants of the new Caladium and ‘Florida Sweetheart’ differed in spathe coloration as plants of ‘Florida Sweetheart’ had white to off-white-colored spathes.
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 leaf coloration as plants of ‘Thai Beauty’ had pale pink to white-colored leaves with white to green-colored margins and venation.

 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 in ground beds in an outdoor nursery in Zolfo Springs, Fla. during the late autumn and early winter. All plants were grown under conditions and 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 29° 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 had been growing in the shadehouse for ten weeks from planting tubers when the photographs and the detailed description were taken. Plants had been growing in the outdoor nursery for eight 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.
