| Scientific Name | Protea neriifolia R.Br. | Higher Classification | Dicotyledons | Family | PROTEACEAE | Common Names | Baardsuikerbos (a), Baardsuikerkan (a), Blousuikerbos (a), Blou-suikerbos (a), Blousuikerkan (a), Blue Sugarbush (e), Narrow-leaved Sugarbush (e), Oleander-leaved Sugarbush (e), Roosboom (a), Suikerbos (a) |
National Status | Status and Criteria | Least Concern | Assessment Date | 2019/06/10 | Assessor(s) | A.G. Rebelo, H. Mtshali & L. von Staden | Justification | Protea neriifolia is endemic to the Western and Eastern Cape Provinces of South Africa. It is widespread, with an extent of occurrence (EOO) of 63 770 km². It is common and abundant across much of its range. While some genetic contamination is likely occurring due to hybridisation between planted varieties for the cut-flower trade and wild populations, the overall population is stable. It is therefore assessed as Least Concern. |
Distribution | Endemism | South African endemic | Provincial distribution | Eastern Cape, Western Cape | Range | A widespread species in the mountains of the Western Cape and Eastern Cape Provinces, South Africa. This species is known from Hottentots-Holland to Riviersonderend Mountains and Langeberg to Winterhoek Mountains and Elandsberg; also on the Rooiberg, Kammanassie Mountains and Potberg, with an isolated population between Tulbagh and Ceres. |

Mature individuals are killed by fires, and only seeds survive. Wind-dispersed seeds are stored in fire-resistant inflorescences, and released after fires. It is pollinated by birds. |
Threats | | Protea neriifolia is extensively grown and there is probably significant genetic contamination by extensive planting of protea orchards adjacent to natural populations without regard to genotype or pollen movement. |
Population | This species doe not occur naturally on the Cape Peninsula, it has been extensively planted there. It typically forms dense stands over wide areas. The population is currently stable.
| Population trend | Stable |
