THIS IS A RARE WEED, a deadly poisonous, smelly shrub that grows to 1-3m, with stems that become woody as it matures. It has hairless, alternate leaves (20-120mm x 5-30mm) which smell rubbery and foul when bruised. The dense greenish-yellow tubular flowers are 15-23mm long and fragrant at night, appearing from November to June, followed by glossy, purplish-black berries. Green cestrum produces many long-lived, widely dispersed seeds, and forms dense, shady masses. It prefers damp conditions, is moderate to highly shadetolerant, and grows in most soil types, and hot or cold conditions.
