Low growing perennial, stems to 6 m long. Fleshy succulent leaves 7-12 cm long. Large (up to 10 cm diameter) many petalled yellow flowers can be produced year-round but most common Oct-Feb. Fleshy fruit. Hybrid plants are slightly smaller with pink, orange, yellow or whitish flowers. Hybrid plants do not form seeds but spread by stem fragments.
Certainly tidal, possibly birds.
Forms mats over sand dunes and open areas displacing other vegetation. Can also change structure of sand dunes. Hybridises with and replaces the much smaller pink flowered native iceplant (Disphyma australe).
1. Pull up plants by hand. Plants can be left upside down to die or heaped (but this heap may need to be sprayed in case of regrowth). Best suited to smaller infestations.
2. Spray (5ml triclopyr + 1ml penetrant/L or 10ml glyphosate/L (untested))
Caution: when using any herbicide or pesticide PLEASE READ THE LABEL THOROUGHLY to ensure that all instructions and safety requirements are followed.
