Sicklethorn (Asparagus falcatus) is an emerging environmental weed in south-eastern Queensland. It is occasionally cultivated as a garden ornamental, and like other asparagus ferns (Asparagus spp.) it is spread into nearby bushland areas by birds and other animals that eat its fruit. This species prefers moist semi-shaded situations, and in recent years it has become more and more common in vegetation along waterways (i.e. in riparian areas) in and around Brisbane.
