Abstract

A new and distinct cultivar of Colocasia plant named ‘Mojito’, characterized by its tall and upright plant habit; vigorous growth habit; rapid growth rate; large ovate-shaped variegated leaves that are green, dark green and black in color; and red purple-colored leaf petioles with very dark-colored longitudinal streaks and stripes.

Description

Botanical designation: Colocasia esculenta.

Cultivar denomination: ‘MOJITO’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Colocasia plant, botanically known as Colocasia esculenta, and hereinafter referred to by the name ‘Mojito’.

The new Colocasia plant is a naturally-occurring branch mutation of Colocasia esculenta ‘Midnight’, disclosed in U.S. Plant Pat. No. 17,887. The new Colocasia plant was discovered and selected by the Inventor on a single plant of ‘Midnight’ within a population of plants of ‘Midnight’ in a controlled greenhouse environment in Apopka, Fla. in May, 2007.

Asexual reproduction of the new Colocasia plant by tissue culture in a controlled environment in Apopka, Fla. since Nov. 15, 2007 has shown that the unique features of this new Colocasia plant are stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

Plants of the new Colocasia 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 ‘Mojito’. These characteristics in combination distinguish ‘Mojito’ as a new and distinct cultivar of Colocasia:

• • 1. Tall and upright plant habit.
  • 2. Vigorous growth habit; rapid growth rate.
  • 3. Large ovate-shaped variegated leaves that are green, dark green and black in color.
  • 4. Red purple-colored leaf petioles with very dark-colored longitudinal streaks and stripes.

Plants of the new Colocasia differ from plants of the parent, ‘Midnight’, in the following characteristics:

• • 1. Plants of the new Colocasia are more vigorous and grow faster than plants of ‘Midnight’.
  • 2. Plants of the new Colocasia are larger than plants of ‘Midnight’.
  • 3. Plants of the new Colocasia have larger leaves than plants of ‘Midnight’.
  • 4. Plants of the new Colocasia and ‘Midnight’ differ in leaf color as plants of ‘Midnight’ have black-colored leaves.
  • 5. Plants of the new Colocasia and ‘Midnight’ differ in leaf petiole coloration as plants of ‘Midnight’ have black-colored leaf petioles.

Plants of the new Colocasia can be compared to plants of Colocasia esculenta ‘Illustris’, not patented. In side-by-side comparisons conducted in Apopka, Fla., plants of the new Colocasia differed primarily from plants of ‘Illustris’ in the following characteristics:

• • 1. Plants of the new Colocasia and ‘Illustris’ differed in leaf color and color pattern as plants of ‘Illustris’ had leaves with green-colored venal areas and black-colored intervenal areas.
  • 2. Plants of the new Colocasia and ‘Illustris’ differed in leaf petiole coloration as plants of ‘Illustris’ had blackish brown and green-colored leaf petioles.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs illustrate the overall appearance of the new Colocasia plant. These photographs show 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 Colocasia plant.

The photograph on the first sheet is a side perspective view of a typical plant of ‘Mojito’ grown in a container.

The photograph on the second sheet is a close-up view of the upper surface of a typical leaf of ‘Mojito’.

The photograph on the third sheet is a close-up view of typical leaf petioles of ‘Mojito’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown in 20-cm containers in Apopka, Fla. during the summer in a polyethylene-covered shaded greenhouse in Apopka, Fla. under conditions and cultural practices which approximate those generally used in commercial Colocasia production. During the production of the plants, day temperatures ranged from 23° C. to 33° C. and night temperatures ranged from about 20° C. to 33° C. Plants were four 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.
