Huge palm-like lobed leaves to 1 - 3 feet wide, and 1 - 2 foot long clusters of flowers followed by attractive spiny pods. Good for a quick screen or tropical effect in the border. Any soil but doesn't like wet feet. Thrives in full sun, heat and moisture. In Zones 8 - 10 it is perennial and becomes tree-like.
The poisonous seeds (warn children) are the source of the purgative 'Castor Oil', also used for illumination, soapmaking, lubrication, etc. Much used by the ancient Egyptians, and mentioned by Herodotus. Many medicinal uses. Silkworms can be fed on the leaves. Stems used in papermaking. Ecuadorian Indians string the seeds and burn them like candles. Scalded leaves once used externally as a galactagogue. Foliage sometimes causes rash.
Soak seed overnight and plant in pots to sprout in about 1 - 12 weeks at warm temperatures. Plant out in May. Seed half life about 13 years. A trick which often increases and speeds germination is to break off the "snout" (caruncle) of the seed before planting. Lightly sanding the tip where the "snout" was helps even more on dormant lots. Seed half life about 13 years.
