![]() Bulbous buttercup ( Ranunculus bulbosus), which is considered a potential famine food, has bulbous roots that are caustic when fresh but can be eaten when they're boiled or completely dried. The most pernicious culprits in North America include tall buttercup ( Ranunculus acris), creeping buttercup ( Ranunculus repens) and cursed buttercup ( Ranunculus sceleratus), to name a few. Dead and dried plants are generally considered safe. While buttercups vary in levels of toxicity, individual plants are at their most toxic in spring when they're alive and flowering. Swallow some buttercups and you'll find yourself in a world of hurt, including but not limited to symptoms like abdominal pain, diarrhea and vomiting, dizziness and even paralysis. The toxic oil is also a serious eye irritant. (-2 C) and thrive best in USDA zones 8 to 10. They are easily damaged by temperatures below 28 degrees F. The plants aren’t very hardy and may be annual in colder zones. The almost unpronounceable name covers a large group of perennials from Asia and Europe. ![]() If the leaves are chewed by humans or beasts, blisters may form on the lips and face. Ranunculus buttercup plants produce cheery, multi-petaled flowers. Contact with protoanemonin will mess you up in a dermatitis kind of way - causing burning and itching with accompanying rash and blisters. When the leaves of buttercups are crushed or bruised they release a compound called ranunculin that breaks down into an acrid, toxic oil called protoanemonin. Int Rev Cytol Suppl, Vol 11A (pp 71–111).All species of ranunculus are poisonous to both animals and humans. In: Vasil IK (Ed) Perspectives in Plant Cell and Tissue Culture.

Persian buttercup (Ranunculus asiaticus) is often referred to as bedding ranunculus as it's a superb flower for adding a splash of colour to pots and borders, although blooms are relatively short-lived, lasting for around six weeks.
