Asparagus plant (sometimes erroneously called a 'fern') is a serious environmental weed. Ekibin Creek has a limited number of outbreaks, probably released from dumped garden refuse or from visiting birds dropping seed. A confusing variety of plants from the genus Asparagus are non-native environmental weeds in Australia. This outbreak, which we have been tackling for more than a year, is probably "Feathered asparagus" (Asparagus plumosus), a native to South Africa. (It is possible that it is A. africanus which has orange berries rather than A. plumosus which has black berries -- we'll have to wait till after it fruits). We are achieving some success using a combination of physical removal of the underground crowns (labour intensive) and by spaying the foliage with a mixture of Starane and diesel (requires follow-up).
