The pollen it releases contains poison. If this Pokémon is raised on clean water, the poison’s toxicity is increased.
This Pokémon is highly sensitive to temperature changes. When its bud starts to open, that means spring is right around the corner.
When the sun’s light strengthens, the bud atop this Pokémon’s head opens. This is a sign to the people that the harsh winter is over, and the season of budding has begun.
