I do not know if this shrub has been identified correctly. Also known as - Poison Bush
Native to Africa, but widely grown as an ornamental plant in India because of the profuse white flowers that are fragrant. The latex of the plant is used by tribes in Africa to poison the tips of the arrows. However,while all parts of the plant are poisonous, the black seeds that follow the flowering is said to contain the highest amount of the toxin.
The small five petal flowers are white, tinged with pink. Flowering occurs mid February onwards. And leaves are thick, dark and stiff.
Though fragrant and beautiful, it has been recommended that the plants are not planted in school campuses.
