Oleander

Oleander is a popular ornamental plant used to decorate schools, parks, and homes worldwide. Notably, it is the official flower of Hiroshima, as it was the first to bloom after the 1945 atomic bomb explosion. Despite its beauty, every part of the oleander is highly poisonous; its toxins are so potent that even consuming honey made by bees that have processed its nectar can be fatal.
