Vileplume, like Gloom, is based on the rafflesia arnoldii, a foul-smelling flower known as the world's largest single flower. This Pokémon more strongly resembles the flower than Gloom, which may represent the budding stage of the rafflesia. Vileplume's flower also looks alike to several other genus of rafflesia, notably cantleyi, keithii, pricei, panchoana and speciosa, of which the petal shape is a closest match. Female Vileplume may be based on Rafflesia hasseltii, as its petals have distinctively larger blotches than other genus of Rafflesia.

One of my favorite pokemon! <3
