Flower

Flowers appear in  and Kingdom Hearts Chain of Memories, taking residence within the Lotus Forest in Wonderland. They are giant, talking plants who reward people for using items, such as Potions or Ethers, on them. All flowers, except the one that can enlarge people, can only take and give once, after which they merely chat with Sora.

Kingdom Hearts
Several flowers appear in Lotus Forest and ask Sora to give them items. While most repay Sora with other items, one flower enlarges him, similar to the effect of drinking the potion in the Bizarre Room. Sora's enlargement allows him to progress further through Wonderland and obtain the Claw Marks evidence, which is needed to help prove Alice's innocence at her trial.

Later on, after Alice goes missing at her trial, a flower is seen opening its petals and then shooting a boulder out onto the ground nearby, at which the Cheshire Cat appears on top of it.
