You mean Ammobium calyceroides, which comes from Tasmania??
Invasive plant.
Ammobium (includes Nablonium; Asteraceae)
Tasmania has two species of Ammobium. A. calyceroides (=Nablonium calyceroides) is a native rosette species with spiny inflorescences. It is common along the west coast. The other species (A. alatum) is a largish, erect introduced perennial herb.
