Heart Seeds

The Heart Seeds (こころの種) are small coin-like chips that are given by people's Heart Flowers after being purified by Pretty Cure. They are needed in order to restore the Tree of Hearts, by collecting them inside the Heart Pod.

Another kind of Heart Seed is the Pretty Cure Seed (プリキュアの種), which is a Heart Seed inside the heart which can only be summoned by a fairy from the Tree of Hearts. The Pretty Cure Seed is the mark of a Cure, and by putting it inside the Heart Perfume or Shiny Perfume, it is possible for those with Pretty Cure Seeds to transform. The Pretty Cure Seeds do not necessarily need to have the same color as the person's Heart Flower's Heart Seed, as Kurumi Erika's Pretty Cure Seed is dark blue despite her Heart Flower bearing a light pink Heart Seed.

The Heart Perfume is also capable of holding a normal Heart Seed inside. These Heart Seeds, depending on the colors, will give the users different sub-powers to use. Only two colored Heart Seeds have been seen used whithin the series: The red Heart Seed speeds up Pretty Cure, and the turquoise Heart Seed calms the mind. These two Hearts Seed have only been used when transformed and untransformed respectively.
