USPP34729P2 - Colocasia plant named ‘corede’ - Google Patents

Abstract

A new cultivar of Colocasia plant named ‘Corede’ that is characterized by its corrugated foliage with a reflective sheen, its black foliage with bright pink mid-veins, its petioles that are dark maroon-black in color, its plant height of 1.2 to 1.5 m, and its clumping plant habit.

Description

Botanical classification: Colocasia esculenta.

Cultivar designation: ‘Corede’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Colocasia esculenta and will be referred to hereafter by its cultivar name, ‘Corede’. ‘Corede’ represents a new tropical plant used as a landscape and container plant in tropical and subtropical areas.

The new cultivar was derived from a controlled breeding program conducted by the Inventor at his nursery in Louisville, Ky. The overall purpose of the breeding program is to make selections of Colocasia plants with unique foliage coloration and distinctive leaf veins.

‘Corede’ arose from a cross made in June of 2017 between unnamed and unpatented Colocasia esculenta plants from the Inventor's breeding program as both the female and male parents. ‘Corede’ was selected as a single unique plant in August of 2018 from amongst the seedlings derived from the above cross.

Asexual propagation of the new cultivar was first accomplished by root cuttings by the Inventor in Louisville, Ky. in August of 2018. Asexual propagation by root cuttings and tissue culture using meristematic tissue has shown that the characteristics of the new cultivar are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and represent the characteristics of the new cultivar. These attributes in combination distinguish ‘Corede’ as a new and unique cultivar of Colocasia.

• • 1. ‘Corede’ exhibits corrugated foliage with a reflective sheen.
  • 2. ‘Corede’ exhibits a black foliage with bright pink mid-veins.
  • 3. ‘Corede’ exhibits petioles that are dark maroon-black in color.
  • 4. ‘Corede’ exhibits a plant height of 1.2 to 1.5 m.
  • 5. ‘Corede’ exhibits a clumping plant habit.

The female parent of ‘Corede’, differs from ‘Corede’ in having a shorter plant height and foliage that lacks pink veins. The male parent of ‘Corede’, differs from ‘Corede’ in having green foliage with white veins and maroon-red petioles, and in producing runners (not clump-forming). ‘Corede’ can be most closely compared to the Colocasia cultivars ‘Black Sapphire Gecko’ (U.S. Plant Pat. No. 27,966) and ‘Nancy's Revenge’ (not patented). ‘Black Sapphire Gecko’ is similar to ‘Corede’ in having heart shaped foliage and dark black-maroon petioles. ‘Black Sapphire Gecko’ differs from ‘Corede’ in having foliage that is all black in color and lacks pink veins and foliage that is less corrugated and ruffled. ‘Nancy's Revenge’ is similar to ‘Corede’ in having heart shaped foliage and a clumping habit. ‘Nancy's Revenge’ differs from ‘Corede’ in having green foliage with white mid-veins.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying color photographs illustrate the overall appearance and distinct characteristics of the new Colocasia, ‘Corede’. The photographs were taken of 2 year-old plants as grown outdoors in a trial garden, in full sun, under 2 mm poly in Louisville, Ky.

The photograph in FIG. 1 provides an overall view of the mature foliage and plant habit of ‘Corede’.

The photograph in FIG. 2 provides a close-up view of the upper leaf surface of ‘Corede’.

The colors in the photographs are as close as possible with the digital photography techniques available, the color values cited in the detailed botanical description accurately describe the colors of the new Colocasia.

DETAILED BOTANICAL DESCRIPTION OF THE PLANT

The following is a detailed description of a division from a 2-year-old plant of the new cultivar plants as grown outdoors, in full sun, under 2 mm poly in Louisville, Ky.
