Agapanthus 08:Layout 1 25/10/10 2:43 PM Page 1 Environmental Weed Fact Sheet 1 Agapanthus Botanical name: Agapanthus praecox ssp.orientalis Common names: Agapanthus, lily of the Nile, African lily Origin: South Africa How it spreads Agapanthus produce numerous small black seeds from the end of summer into autumn. Seeds can be dispersed by wind or water and may also be transported by soil movement and by dumping of garden refuse in bushland areas. Agapanthus also spread underground by rhizome (root) growth, or vegetatively by fragments. Environmental impact The dense clumping roots of agapanthus displace indigenous grasses and groundcovers and prevent overstorey regeneration. Plants are adapted to a wide range of soil types and conditions and often invade bushland, gardens and roadside areas. How to identify • Hardy, perennial lily that grows in dense clumps. • Thick, succulent, dark green, strap-like leaves up to 60cm long. • Large rounded heads of tubular flowers, blue or white, produced on long stems to 1.2m in summer. • Small, shiny black seeds produced in three-sided capsules from the end of summer to autumn. • Extensive fleshy root system. Agapanthus 08:Layout 1 25/10/10 2:43 PM Page 2 Environmental Weed Fact Sheet 1 How to control agapanthus Removal by hand Cut flower heads off before seeds form to help prevent spreading. Dig out clumps with a mattock, ensuring that all root material is removed. Tasman flax lily Replacement planting Tasman flax fily (Dianella tasmanica) and spiny mat rush (Lomandra longifolia) are suitable alternatives to agapanthus.

Chemical control Agapanthus may be controlled with the use of appropriate herbicides. Search the PUBCRIS database for registered products at www.apvma.gov.au. Read the label of any chemical before use and ensure that you follow the manufacturer’s instructions. Disposal Dispose of agapanthus in regular green waste collections, burn in a hot fire or seal in plastic bags and dispose of the material at your local tip. Do not dump agapanthus as it will regenerate.
