Cunjevoi

Alocasia brisbanensis

The Story

Plant Bio

Alocasia brisbanensis, commonly known as cunjevoi, is a massive, robust evergreen perennial native to the rainforest margins of eastern Australia. It forms a bold, clump-forming architectural feature with an erect or decumbent fleshy stem covered in the persistent brown bases of old leaves.

This species is distinguished by its enormous, glossy green, spade-shaped leaves up to 70 centimetres long, which are held on thick, fleshy petioles. In summer, it produces highly fragrant, yellowish-green spadices enclosed in spoon-like spathes that emit a sweet, rose-like scent.

Uses & Benefits:

Provides a massive, bold architectural presence with its giant, glossy green leaves and highly fragrant summer inflorescences.

Serves as an excellent structural understorey plant for shaded, wind-protected coastal or tropical garden designs.

Acts as a larval host plant for native hawk moths and supports various local insect pollinators.

Planting

How to Grow

Select a sheltered position in partial or dappled shade, completely protected from harsh, direct afternoon sun.
Incorporate generous amounts of well-rotted organic matter into a moist, free-draining soil to mimic a rainforest floor.
Plant the rhizome at the same depth it was in the container, ensuring the crown sits just above the soil level.
Water thoroughly after planting and maintain consistent moisture, particularly during the warm summer growing months.

Pro Tip

Remove individual yellowing or damaged leaves by cutting them cleanly at the very base of the petiole, avoiding any arbitrary hacking into the main fleshy stem which invites rot.

Care Guide

Do

Wear thick gloves and protective eyewear when handling, pruning, or dividing to avoid contact with the toxic, irritating sap.
Apply a balanced, slow-release fertiliser during the active spring and summer growing seasons.
Provide high humidity and shelter from cold, drying winds to prevent foliage damage.

Don't

Do not allow the soil to become waterlogged or stagnant, which rapidly induces root rot.
Do not plant in areas exposed to frost or temperatures below 10 degrees Celsius without overhead canopy protection.
Never ingest any part of the plant, as the calcium oxalate crystals cause immediate, severe swelling of the mouth and throat.
