Heart Flowers

The Heart Flowers (心の花) are important items in Heartcatch Pretty Cure!, serving as Pretty Cure's motivation during the season. It is said that each Heart Flower's color and flower type mirrors the owner's feelings and personality, and no Heart Flower is the same. The meanings of the flowers used in the series are mostly from Japanese culture, Hanakotoba (花言葉) in particular. 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, which will happen to color-changed Heart Flowers if not cured in time, and if the flower is completely wilted for too long, the Tree of Hearts will weaken. However, regardless of how strong the negative feeling is, those 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 crystal ball which has the suffering person imprisoned inside of it. The person can only return to normal if the Heart Flower is purified, and the crystals are put back together again. So far, only Pretty Cure has been seen purifying a wilting Heart Flower, and when it happens, the Heart Flower will start blooming again despite the owner's past feelings.

The Desert Apostles use wilting or negative Heart Flowers to form Desertrians, and it is stated that the more a Heart Flower is wilting, the stronger the Desertrian will be.
