Are Moonflowers and Other Ornamentals Edible?

No. Moonflower (Datura) is potentially lethal — seeds and plant parts are poisonous. The other listed flowers (Evening Promise, Corpses, Columbine, Cosmos) lack safety data for consumption. Never candy or eat ornamental flowers unless confirmed edible.

Stick to known edible flowers: violet petals or scented geranium (Pelargonium) petals. Always verify toxicity before using any plant in food.
