The flowers are produced in large umbels of 30 to 45 centimetres (12 to 18 in) diameter in late summer, each flower small and white. The fruit is a small black drupe 3 millimetres (0.12 in) diameter, and may be toxic to humans. [3] In the wild, the plant achieves a height of 1.2 to 1.8 metres (3.9 to 5.9 ft).
Nerium is a poisonous plant but its bitterness renders it unpalatable to humans and most animals, so poisoning cases are rare and the general risk for human mortality is low. Ingestion of larger amounts may cause nausea, vomiting, excess salivation, abdominal pain, bloody diarrhea and irregular heart rhythm.

Tiny white flowers, typically in three, globe-shaped clusters 4–5 cm (1.6–2.0 in) wide, are produced on tall scapes that grow about the same height as the leaves, about 30–60 cm (12–24 in) high. The flowers bloom from May to July and develop into purple-black edible berries. The leaves go dormant in summer before the fruits ripen.
All parts of the C. thevetia plant are toxic to most vertebrates as they contain cardiac glycosides. Many cases of intentional and accidental poisoning of humans are known. [6] The main toxins are the cardenolides called thevetin A and thevetin B; others include peruvoside, neriifolin, thevetoxin and ruvoside.
The plant is toxic enough to cause human and animal fatalities if ingested. Every part of the plant is poisonous, especially the tuberous rhizomes. As with other members of the Colchicaceae, this plant contains high levels of colchicine, a toxic alkaloid. It also contains the alkaloid gloriocine.
