Disney Fairies: Lily in Full Bloom

Lily has always thought of herself as a garden-talent fairy first and foremost. But after Tink challenges the other talents to think up new ideas, Lily discovers she's pretty good at inventing things, too, like her new flowers, the panglories. They grow anywhere - in dirt, on wood, even on rocks! But then little gray spots pop up, first on the panglories, then on other flowers, until all the plants in Pixie Hollow start losing their colors. Can Lily invent a way out of this new fix?
