USPP33772P2 - Colocasia plant named ‘Pharaohs Mask’ - Google Patents

Abstract

A new cultivar of Colocasia plant named ‘Pharaohs Mask’ that is characterized by its clump forming growth habit, its plant height up to 1.5 m, its leaves that are green in color with margins that are curled under, its leaves that are green in color with margins that are curled under, its petioles that are dark black in color, and its leaf veins that are dark black in color, prominent, and raised starting at the mid-vein and running to the edge of the leaves.

Description

Botanical classification: Colocasia hybrid.

Cultivar designation: ‘Pharaohs Mask’.

BACKGROUND OF THE INVENTION

The present invention, Colocasia ‘Pharaohs Mask’, relates to a new and distinct of Colocasia plant of hybrid origin and is hereinafter referred to by its cultivar name, ‘Pharaohs Mask’. ‘Pharaohs Mask’ is 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 colorful foliage with distinctive leaf veins. ‘Pharaohs Mask’ arose from a cross made in June of 2013 between Colocasia ‘Dark Star’ (not patented) as the female parent and an unpatented and unnamed proprietary plant of Colocasia fontanesii from the Inventor's breeding program as the male parent. ‘Pharaohs Mask’ 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 ‘Pharaohs Mask’ as a new and unique cultivar of Colocasia.

• • 1. ‘Pharaohs Mask’ exhibits a clump forming growth habit.
  • 2. ‘Pharaohs Mask’ exhibits a plant height up to 1.5 m.
  • 3. ‘Pharaohs Mask’ exhibits leaves that are green in color with margins that are curled under.
  • 4. ‘Pharaohs Mask’ exhibits petioles that are dark black in color.
  • 5. ‘Pharaohs Mask’ exhibits leaf veins that are dark black in color, prominent, and raised starting at the mid-vein and running to the edge of the leaves.

The female parent of ‘Pharaohs Mask’ differs from ‘Pharaohs Mask’ in having a “v” shaped pattern on the leaf, flat leaf edges, and petioles that are green in color. The male parent of ‘Pharaohs Mask’ differs from ‘Pharaohs Mask’ in having leaves that are dark green in color without distinct veins and a taller plant height, and in lacking a clump-forming growth habit with runners produced. ‘Pharaohs Mask’ 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 ‘Pharaohs Mask’ in having heart shaped leaves and dark black petioles. ‘Black Sapphire Gecko’ differs from ‘Pharaohs Mask’ in having leaves that are dark purple-black in color on the upper surface and maroon in color on the lower surface that lack prominent veins and curled margins. ‘Nancy's Revenge’ is similar to ‘Pharaohs Mask’ in having large, heart shaped leaves and a clumping growth habit. ‘Nancy's Revenge’ differs from ‘Pharaohs Mask’ in having leaves that are light green in color with creamy white centers that lack curled margins and petioles that are green in color.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new Colocasia, ‘Pharaohs Mask’. The photographs were taken of an eight-month-old plant as grown outdoors in a trial garden in Louisville, Ky.

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

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

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 2-month plants from a tissue culture plug in a 2-quart container with mature data taken from one or two-year-plants of the new cultivar as grown in one-gallon containers outdoors under two mm poly in Louisville, Ky.
