Query: Quick grower, plant sap (milk) nerve irritant!

Stay away from the sap! Does produce quite a bit of milky white sap when broken or cut! Wound up in the hospital with extreme eye irritation! Some get anaphylactic shock shock from it! Wash your hands well after touching!Otherwise, this plant grows quickly and propagates easily by breaking off a piece and sticking it in the ground.
