What does it look like?

Green godess arum is a clump-forming, evergreen perennial (to 1.5 m) growing from tubers, with large glossy, leathery, dark-green, arrow-shaped leaves (to 45 cm x 25 cm) with pale fine veins and wavy margins, held upright on long stalks (to 1 m).

From September to December a yellow, finger-like spike, surrounded by a large, greenish-white, funnel-shaped, modified leaf (to 25 cm), forms a flower-like structure that is followed by round green or yellow berries (1 cm) on the flower stalk after the leaves die back

Why is it a problem?

Forms dense cover on the ground in open sites, shading out native plants and preventing native plants establishing. Tolerates a wide range of conditions including wet, wind, salt, hot to cold, most soil types and moderate shade, and is drought-resistant once established.

Control Methods

Physical control

  • Dig out scattered plants (all year round): remove all pieces of root and dispose of them at a refuse transfer station.

Herbicide control

  • Cut and paint stumps: metsulfuron-methyl 600g/kg (1g) + glyphosate (100ml) + penetrant/1L water. Mulch the leaves and dispose of seeds at refuse transfer station.
  • Weed wipe: metsulfuron-methyl 600g/kg (1g) + glyphosate (150ml) + penetrant /1L water.
  • Overall spray: metsulfuron-methyl 600g/kg (3g) + glyphosate (150ml) + penetrant /10L water.
