The only thing dangerous about castor bean plants is the seeds. Make sure
children can't get hold of them. I can't imagine a dog eating them, but you
should probably keep them out of the dogs' reach to be sure. The plants
themselves are harmless. A castor plant is one of the leading characters in the
Book of Jonah. it is sometimes translated gourd, but we now know it was a
castor oil plant, & the story makes sense.
