Grass Weeds The grassy weeds are commonly overlooked, however, exotic grass species are invading roadsides, reserves and bushland in Sydney and aggressively displace native ground covers. Although many of these species are desirable pasture grasses and turf grasses in home lawns, parks and playing fi elds, they are problematic bushland and garden weeds because they are capable of setting copious volumes of viable seed within a short time of germination. While many of these species only invade disturbed areas with adequate light levels, some of these species are also shade tolerant, and thus can invade intact bushland areas. The main weed species are featured in the following pages but below is a list of Other Problematic Grass Weeds (Some of these species are declared noxious in different parts of Sydney) Common Name Botanical Name African Feather Grass Pennisetum macrourum African Love Grass Eragrostis curvula Bamboo Phyllostachys species Broadleaf Paspalum Paspalum wettsteinii Buffalo Grass Stenotaphrum secundatum Chilean Needle Grass Nassella neesiana Columbus Grass Sorghum x almum Common Couch Cynodon dactylon Coolatai Grass Hyparrhenia hirta, H. rufa Fine Bristled Burr Grass Cenchrus brownii Giant Pigeon Grass Setaria verticillata Giant Parramatta Grass Sporobolus fertilis Giant Paspalum Paspalum urvillei Giant Rats Tail Grass Sporobolus pyramidalis Giant Reed Arundo donax Grader Grass Themeda quadrivalvis Johnson Grass Sorghum halepense Kikuyu Pennisetum clandestinum Large Quaking Grass Briza maxima Mexican Feather Grass Nassella tenuissima Mossman River Grass Cenchrus echinatus Olive Hymenachne Hymenachne amplexicaulis Parramatta Grass Sporobolus africanus Red Natal Grass Melinis repens Rhodes Grass Chloris gayana Slender Pigeon Grass Setaria geniculata Spiny Burr Grass Cenchrus longispinus/C. incertus Grass Weeds 51
