Angled Onion (Allium triquetrum), a noxious weed and riparian invader, and a plant that surprisingly does not seem to have a record in Australia prior to 1900 and in Victoria before 1942. Being both edible and ornamental, it is not entirely clear for which purpose this Mediterranean species was introduced, but it is now a problematic infestor of damp environments and watercourse areas throughout much of the state. In addition to reproducing vegetatively, the seeds of Angled Onion are tolerant of water transport and employ an oil to attract ants, which make their own contribution to local seed dispersal.
