Vileplume has a Prussian blue-colored, bipedal body like its pre-evolutions, but has changed in that it now has a much larger "flower" on its head. This "flower" is slightly different from Gloom's flower, although it still resembles a rafflesia flower. Vileplume are said to have the largest petals in the world, and they contribute to a large percentage of their height. The size of the petals in relation to the rest of the body make Vileplume very sheltered from the sun, as the petals almost act as a sun visor.
A female has fewer, but bigger, spots on its petals.
Vileplume scatters toxic spores and releases noxious gases. Its toxic pollen sometimes triggers atrocious allergy attacks. It also has the world's largest petals that it uses to attract prey, and the larger its petals, the more pollen it scatters. The allergenic pollen is said to turn the air around Vileplume yellow, and is known to cause paralysis.
The bud bursts into bloom with a bang. In seasons when Vileplume produces more pollen, the petals shake out heavy clouds of it with each step, turning the air around it yellow. Vileplume may also loudly flap its flower petals to scatter its pollen. The petals are used to attract prey that is then doused with toxic spores. Once the prey is immobilized, Vileplume catches and devours them. Because of the flower's huge size, Vilplume has a hard time lifting up its head.
Vileplume live in grassy plains, and can also be found in tropical areas such as jungles and swamps, where the ground is rich in nutrients. It shares its home range with Oddish and Gloom.
