Common Names Star of Bethlehem, Madam Fate
Status Exotic: Naturalised

Diagnostic: An easily recognisable herb because of its rosette leaf arrangement. Its leaves are pinnately-lobed, the margins are lined with teeth, and they lack a petiole. The mid-vein is also very prominent. The white flowers have a long stalk and are five-petalled. It prefers shady areas.

Interesting Facts: One has to be careful handling this plant as it contains a poisonous white sap (lobelanidine) that can cause irritation on contact. It also may even cause blindness if it gets onto the eye, and give a burning sensation when ingested (FloraFaunaWeb, 2010).

The Star of Bethlehem is widely cultivated as an ornamental plant, and likely as a result, also naturalised in many tropical and subtropical countries (eFloras, 2008).
