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.
- Dig out scattered plants (all year round): remove all pieces of root and dispose of them at a refuse transfer station. It is often difficult to get all tubers by digging so regular checking of site and control will be necessary.
- Cut and paint stumps: 1g metsulfuron-methyl (600g/kg) per 1L water. Mulch the leaves and dispose of seeds at refuse transfer station. Weed wipe leaves with same herbicide mix.
- Overall spray: 5 metsulfuron-methyl (600g/kg) + penetrant per 10L water.
