Hi ya Chef from home of the best food to be found, New Orleans!!!!! Dare ya to say otherwise ;o)
I have never heard that about plumbago being edible but would love to request your list of edible flowers!!!!
Thanks mike

I did a search for Plumbago auriculata, one with the word therapeutic and a second search with the word toxicity.

The sap (leaves, stems) may cause dermatitis, the roots have a chemical that is toxic (emetic: nausea, vomiting).

In my brief search, I found nothing regarding the flowers or petals. Could be that just a few for color are harmless but you won't know until you try it. You might rub some petals on the inside of your wrist or elbow to see if you have a reaction (dermatitis) before eating them.

Chef Carson,
I would love that list of edible flowers (if you still have it, that is).
Do you know where I could find a complete list of edible plants?
Thanks,
Carrie

I don't ordinarily recommend links without checking out their validity, but this looked intriguing. It said there are 75,000 edible species of plants, so that would make a single list awfully hard to handle:-) It also said we only tend to eat about 5,000 of those species.

Hi I ahve also read edible, and toxic so confusing. My husband is a French private chef on the cote d'azur. I grow all his microgreens, herbs, edible flowers, and lots of organic veg and fruits, and nuts. Might get him to taste, and see. He proposed I do lol. Also interested in your list juliemsofonea@gmail.com
