About
Osteospermum moniliferum (synonym Chrysanthemoides monilifera) is an evergreen flowering shrub or small tree in the daisy family, Asteraceae. It is native to southern Africa, ranging through South Africa and Lesotho to Mozambique and Zimbabwe.
Most subspecies have woolly, dull, serrate, oval leaves, but the subspecies rotundatum has glossy round leaves. Subspecies are known as boneseed and bitou bush in Australasia, or bietou, tick berry, bosluisbessie, or weskusbietou in South Africa. The plant has become a major environmental weed and invasive species in Australia and New Zealand.
Where it grows
Osteospermum moniliferum occurs naturally in coastal areas of South Africa, reaching into Lesotho, Zimbabwe, and southern Mozambique. Subspecies rotundatum is concentrated along the eastern coast of South Africa from its southern tip through KwaZulu-Natal to southern Mozambique. Subspecies moniliferum is concentrated around Cape Town and the Cape Peninsula on South Africa's south western coast, where its native habitats include the Cape Flats Dune Strandveld. Subspecies canescens is native to Kwazulu-Natal, the Northern Provinces, and Free State of South Africa and to Lesotho. Subspecies septentrionale is native to Mozambique, Zimbabwe, and the Northern Provinces.
