Ricinus communis

Ricinus communis Castor oil plant

Ricino

This attractive plant can grow as high as 5 metres tall. It was native to SE Mediterranean,  East Africa and India but has now naturalised in many warm climates. It had largish, glossy green leaves, often tinged red and flowers from April to September. It can cause severe allergies, especially Asthma and also allergic reactions to anyone allergic to Ricinus could develop skin rashes. The fruit, bean-like structures are highly poisonous and could cause death in large quantities. Castor oil is a lubricant for motors.

This small plant is native to Europe, but has now been introduced to other continents. It flowers from April to June and can grow from 5-20cms tall. The leaves are very hairy. I can't fins any references to it being a parasitic plant.
