Heart Flowers

A Heart Flower (心の花) is a main term in the Heartcatch Pretty Cure!, serving as Pretty Cure's motivation during the season. It is said that each Heart Flower's color and flower race mirrors the owner's feelings and personality, and no Heart Flower is the same. The flower language used in the series is mostly Japanese. It is shown that a Heart Flower is capable of changing color if a new feeling is more dominant than the previous, but most of the time, the Heart Flower will wilt. However, regardless of how strong the negative feeling is, these feelings will always disappear when purified along with the Heart Flower.

When the Heart Flower is forced out, the body separates into two objects; one crystal containing the Heart Flower, and one a crystal ball which has the suffering person imprisoned. The person can only return to normal if the Heart Flower is purified, and the crystals are attached back again. So far, only Pretty Cure has been seen purifying a wiltering Heart Flower, and when it happens, the Heart Flower will start blooming again despite the owner's past feelings.

The Desert Apostels use wiltering or negative Heart Flowers to form Desertrians, and it is stated that the more wiltering Heart Flowers there is, the stronger the Desertrian will be.
