Rafflesia arnoldii

The world's largest individual flower, and it smells like death/Plants

Rafflesia arnoldii produces the largest individual flower on Earth, sometimes exceeding one meter in diameter. It is a parasitic plant with no stems, leaves, or roots of its own, instead stealing nutrients from tropical vines. The flower smells like rotting flesh to attract pollinating flies, earning it the nickname 'corpse flower.' It takes 9 months to develop and lasts only about 5 days, making it nature's most dramatic and disgusting one-hit wonder.
