Flower

Flowers appear in Kingdom Hearts and take residence within the Lotus Forest in Wonderland. They are giant, talking plants who reward people for using 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 all ask Sora for either a Potion or Ether. While most reward Sora through items such as Hi-Potions, one flower rewards Sora by enlarging 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.

Appearance
Flowers are, true to their name, giant flowers with thick, green shoots and leaves. Some flowers have red petals while others have yellow petals. Usually, their petals are closed into a bud however they bloom when they are given their desired item.

Personality
Not much is known about the flowers as they play a small role in the game however it is known that they are often grateful to those who satisfy them. The flowers are all part of the same community and they make friendships between each other. They are shown to have a certain level of thinking and intelligence as they frequently make remarks and observations about the world around them. Also, they are extremely mysterious, for example, one flower has a strange "power" to enlarge people.

Origin
Flowers originate from Disney's and, much like the game, have little plot significance as they are only ever seen in the background. In the film, there are several different colors and types of flowers.
