Caladium plant named ‘Florida White Ruffles’

Abstract

A distinct cultivar of Caladium plant named ‘Florida White Ruffles’, characterized by its compact and densely-foliated plant habit suitable for container production; upright, outwardly arching and symmetrical plant form; and white and dark green bi-colored leaves that are lanceolate in shape.

Description

Botanical classification/cultivar designation: Caladium×hortulanum cultivar Florida White Ruffles.

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 Caladium, and hereinafter referred to by the cultivar name Florida White Ruffles.

The new cultivar is a product of a planned and controlled breeding program conducted by the Inventor in Bradenton, Fla. The objective of the breeding program is to create densely-foliated compact Caladium cultivars with uniquely variegated foliage.

The new cultivar originated from a cross-pollination made in 1985 of the Caladium×hortulanum cultivar Aaron, not patented, as the female, or seed, parent, with the Caladium×hortulanum cultivar Red Frill, not patented, as the male, or pollen, parent. The cultivar Florida White Ruffles was discovered and selected in 1986 as a plant within the progeny of the stated cross-pollination in a controlled environment in Bradenton, Fla.

Asexual propagation of the new cultivar by tuber divisions in Bradenton, Fla., has shown that the unique features of this new Caladium plant are stable and reproduced true to type in successive generations of asexual propagation.

SUMMARY OF THE INVENTION

The new Caladium has 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 ‘Florida White Ruffles’. These characteristics in combination distinguish ‘Florida White Ruffles’ as a new and distinct cultivar:

1. Compact and densely-foliated plant habit suitable for container production.

2. Upright, outwardly arching and symmetrical plant form.

3. White and dark green bi-colored leaves that are lanceolate in shape.

Plants of the new Caladium can be compared to plants of the female parent, the cultivar Aaron. When grown in side-side comparisons in Bradenton, Fla., plants of the new Caladium differed from plants of the cultivar Aaron, in the following characteristics:

1. Plants of the new Caladium were short than plants of the cultivar Aaron.

2. Plants of the new Caladium had more leaves per plant than plants of the cultivar Aaron.

3. Plants of the new Caladium had lanceolate-shaped leaves whereas plants of the cultivar Aaron had cordate-shaped leaves.

Plants of the new Caladium can be compared to plants of the male parent, the cultivar Red Frill. When grown in side-side comparisons in Bradenton, Fla., plants of the new Caladium differed primarily from plants of the cultivar Red Frill as plants of the cultivar Red Frill had red and dark green bi-colored leaves.

Plants of the new Caladium are similar in leaf coloration to the cultivars White Wing, not patented, and Jackie Suthers, not patented. However, when grown in side-side comparisons in Bradenton, Fla., plants of the new Caladium differed from plants of the cultivars White Wing and Jackie Suthers, in the following characteristics:

1. Plants of the new Caladium were shorter and more compact than plants of the cultivars White Wing and Jackie Suthers.

2. Plants of the new Caladium had narrower leaves, but more leaves per plant than plants of the cultivars White Wing and Jackie Suthers.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearance of the new cultivar, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Caladium. The photograph is a side perspective view of a typical plant of ‘Florida White Ruffles’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph, following observations, measurements and comparisons describe seven-week old plants (from planting a tuber division) grown in Bradenton, Fla. during the spring and summer in a shaded glass-covered greenhouse and under commercial production conditions in 15-cm containers. During the production of the plants, day temperatures were about 32° C., night temperatures were about 21° C. and light levels were about 2,000 to 3,000 foot-candles.
