Caladium plant named ‘Victoria’

Abstract

A new and distinct cultivar of Caladium plant named ‘Victoria’, characterized by its compact, symmetrical, upright, outwardly arching and rounded plant habit; dense and bushy growth habit; undulate strap-like leaves that are rugose giving a highly textured appearance; and red, pink and green-colored leaves.

Description

Botanical designation: Caladium×hortulanum.

Cultivar denomination: ‘Victoria’.

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 strap-leaf Caladium and hereinafter referred to by the name ‘Victoria’.

The new Caladium is a naturally-occurring whole plant mutation of the Caladium×hortulanum cultivar Florida Sweetheart, disclosed in U.S. Plant Pat. No. 8,526. The new Caladium was discovered and selected by the Inventor in a controlled environment in Lake Placid, Fla. on Jun. 15, 2002 from within a population of plants of the cultivar Florida Sweetheart. The new Caladium was selected on the basis of its unique leaf texture and coloration.

Asexual reproduction of the new cultivar by tuber divisions in a controlled environment in Lake Placid, Fla. since Apr. 15, 2003 has shown that the unique features of this new Caladium are stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

The cultivar Victoria 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 ‘Victoria’. These characteristics in combination distinguish ‘Victoria’ as a new and distinct cultivar of Caladium:

• • 1. Compact, symmetrical, upright, outwardly arching and rounded plant habit.
  • 2. Dense and bushy growth habit.
  • 3. Undulate strap-like leaves that are rugose giving a highly textured appearance.
  • 4. Red, pink and green-colored leaves.

In side-by-side comparisons conducted in Lake Placid, Fla., plants of the new Caladium differed from plants of the parent, the cultivar Florida Sweetheart, in the following characteristics:

• • 1. Plants of the new Caladium were more compact than and not as vigorous as plants of the cultivar Florida Sweetheart.
  • 2. Leaves of plants of the new Caladium were more undulate than leaves of plants of the cultivar Florida Sweetheart.
  • 3. Leaves of plants of the new Caladium were more rugose and more textured in appearance than leaves of plants of the cultivar Florida Sweetheart.
  • 4. Under high light conditions, plants of the new Caladium had darker red-colored leaves than plants of the cultivar Florida Sweetheart.
  • 5. Plants of the new Caladium had shorter leaf petioles than plants of the cultivar Florida Sweetheart.

Plants of the new Caladium can be compared to plants of the Caladium cultivar Florida Red Ruffles, disclosed in U.S. Plant Pat. No. 13,136. In side-by-side comparisons conducted in Lake Placid, Fla., plants of the new Caladium differed from plants of the cultivar Florida Red Ruffles in the following characteristics:

• • 1. Plants of the new Caladium were larger than plants of the cultivar Florida Red Ruffles.
  • 2. Leaves of plants of the new Caladium were more undulate than leaves of plants of the cultivar Florida Red Ruffles.
  • 3. Leaves of plants of the new Caladium were more rugose and more textured in appearance than leaves of plants of the cultivar Florida Red Ruffles.
  • 4. Plants of the new Caladium and of the cultivar Florida Red Ruffles differed in leaf coloration.
  • 5. Plants of the new Caladium had lighter-colored leaf petioles than plants of the cultivar Florida Red Ruffles.

Plants of the new Caladium can be compared to plants of the Caladium cultivar Lance Whorton, not patented. In side-by-side comparisons conducted in Lake Placid, Fla., plants of the new Caladium differed from plants of the cultivar Lance Whorton in the following characteristics:

• • 1. Plants of the new Caladium were more compact than plants of the cultivar Lance Whorton.
  • 2. Leaves of plants of the new Caladium were more undulate than leaves of plants of the cultivar Lance Whorton.
  • 3. Leaves of plants of the new Caladium were more rugose and more textured in appearance than leaves of plants of the cultivar Lance Whorton.
  • 4. Plants of the new Caladium and of the cultivar Lance Whorton differed in leaf coloration.
  • 5. Plants of the new Caladium had lighter-colored leaf petioles than plants of the cultivar Lance Whorton.

DETAILED BOTANICAL DESCRIPTION

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. The following observations and measurements describe plants grown in 15-cm containers in Lake Placid, Fla. during the spring in a polyethylene-covered shadehouse and under conditions and practices which approximate those generally used in commercial Caladium production. During the production of the plants, day temperatures ranged from about 21° C. to 38° C., night temperatures ranged from about 10° C. to 21° C. and light levels about 8,000 foot-candles. Plants were about seven weeks from planting tubers when the photographs and the detailed description were taken.
