Description

Castor Bean is a cultivated, annual herbaceous ornamental in the Euphorbiaceae (spruge) family native to Africa. 

Plant in full sun in rich moist soils.  Fertilize regularly for the best growth.  Pruning may be necessary to shape the plant. Plants will have low drought tolerance until well established. 

Insects, Diseases, and Other Plant Problems:  Spider mites occasionally attack plants that are drought-stressed.  If broken seeds are ingested, it is likely to cause death in humans. It may also be fatal to livestock and pets, but it is not often available to them.
