Acaena novae-zelandiae (bidi-bidi,biddy-biddy,bidgee-widgee, or piri-piri-bur) is an ornamental plant native to New Zealand and Australia. It can also be found elsewhere as an introduced species, and is considered a noxious weed in some areas, such as Hawaii and California. The common name bidi-bidi is a corruption of the Māori name for this plant, piripiri.
Bidgee-widgee was used as a tea substitute by early explorers.
Bidgee-widgee is a prostrate herb. One plant can cover up to 4-5 square meters in favorable conditions. A burr is left after the flowers fall.
