Moon Vine – Toxic?

Q: I have been reading and enjoying what you have written about moon vine. Other sites mention poisonous seeds and foliage. I have also read that all parts are quite deadly. You didn’t mention that at all so I wondered if we were talking about the same plants. The photos look the same and I’m aware that some are shrub like and some have a vine habit. I’m trying to root some cuttings and have gotten a little paranoid about handling the plants.

A: Moon vine is a member of the morningglory family. The seeds of morningglory could be considered “toxic” if you eat enough of them but they also produce vomiting and diarrhea which gets the chemicals out of your body before they do much harm. The seeds are not toxic from handling; the vines and leaves are certainly not dangerous.
