It's the seeds inside the casing that are deadly and just to note most plants are deadly to dogs and cats, so why bother planting anything you could say? I manage the garden and pick any seeds that drop. Did you know rhubarb leaves are poisonous, you could argue why grow them, yet the stems are a super food and they go on growing for 10 to 15 years, castor oil plants have 1 season. Like I said before most plants are deadly to dogs and cats but you don't see your dog and cat lapping up plants they have more sense than some people 😉.
