Thevetia ahouai is usually an evergreen shrub growing 1 - 3 metres tall, though sometimes it becomes a small tree.
The species can be used as an ornamental, and have bright yellow flowers which give off a subtle scent.
When cut the leaves and bark exude a milky white sap which can cause irritation when coming in contact with the skin. Thevetia ahouai's fruit are 2-3 cm long to 3-5 cm wide with bright red color. Special caution must be taken with children and pets as they're highly toxic.
