Guardian Garden - Mamori Hito no Niwa Comic

Kisaragi Hinata is a cheerful high-school girl who works at her father’s flower shop alongside her best friends. Her mother died when Hinata was a baby, and her father disappeared ten years ago, leaving her without a family and with lasting pain over that loss. One day, an organization that seems to know a secret about Hinata kidnaps her. Two striking people with extraordinary abilities, and a connection to her father, come to her rescue. Hinata then discovers she can communicate with plants, and wonders whether this ability is the reason people are pursuing her.
