The Blooming Flowers Pokémon Center promotion was a merchandise campaign held in May 2010 in Pokémon Center stores across Japan. The merchandise in this promotion consists mainly of hair accessories and stationery, and features some of the "cuter" Pokémon surrounded by flowers. This suggests that the promotion was targeted more towards females.
