Ornament
 
INVADES
Roadsides, disturbed areas, wastelands, urban open space, forest edges/gaps, riparian vegetation and coastal sand dunes.
 
IMPACTS
Smothers native trees, out-competes understorey plants and alters fire regimes (Langeland et al., 2008; USDA-NRCS, 2011). On Christmas Island (Indian Ocean), it is ‘rampant on sea and inland cliffs and in previously mined areas where it may be hampering the annual migration of crabs and interfering with natural regeneration’ (Swarbrick and Hart, 2000). It has been estimated to cover 20% of the island of Saint Eustatius (Caribbean) (Ernst and Ketner, 2007).
