Plant description

colocasia esculenta illustris

colocasia esculenta illustris.

Colocasia 'Illustris' is a tender herbaceous perennial with beautiful large dark green, arrow shaped leaves, with contrasting lighter veins. It likes a sunny to partly shaded position, and does best in a moist soil with a high organic content. Brighter light will result in deeper colouring. Tolerates a wet soil, so is good for pond plantings and rain gardens. It is frost tender, but in cooler areas it be grown in a container and moved to a sheltered position in winter. It grows from an underground rhizome or tuber, so can resprout if the foliage is damaged by cold or dryness, and will form a clump. A great foliage contrast plant, and gives a tropical feel to the garden.

Propagation is by division of the rhizomes.

All parts of the plant are poisonous.

Colocasia esculenta 'Illustris' is also known as Colocasia antiquorum.
