Plumbago is not formally considered poisonous, but due to a very bad episode we experienced with this plant, we consider it lethal. All three are now fine. Poisoning was confirmed on the last and longest case, although the exact type could not be determined. The only item that all 3 had access to was a Plumbago Auriculata plant. Use your own discretion, we no longer have any Plumbago plants.
Danger can be varied depending on particular species and amount consumed.
