It prefers a well drained fertile moist sandy to clay soil in an open sunny position and is frost and drought tender.
 
The Castor Oil Plant is grown for its foliage and colourful fruit. It is planted in parks and gardens along borders or around a water feature for a tropical effect. In cooler climates it is grown as a glasshouse specimen or it can be grown in pots and tubs. It is suitable for coastal regions and establishes in one season. Under ideal conditions it can become a weed as it self-sows readily. ID 850
