Castor beans give us a tropical paradise in a northern climate, for they quickly grow full and bushy from direct sowing after frost. The large, impeccable leaves and amazing towers of colorful bristly seedpods amp up the summer garden. Do not grow in areas where children or pets are present, as seeds are highly poisonous. Caution: wear gloves when handling the seeds or plant, as contact with skin can cause skin irritation or toxic effects. All parts of the plant are toxic if ingested.
