Daffodil describes her as "annoying." However, from what Ivy can tell, she is a pleasant and quiet person.
Daisy was first mentioned by Daffodil, who said that her sister was extremely annoying and would not be allowed to join their secret club. Daffodil mentioned Daisy again, saying that Daisy would probably tell on her if she snuck out to spy on the Wingwatchers meeting. She is later mentioned to have tricked Daffodil into going to school early. Daisy later showed up at the Wingwatcher welcome ceremony, waving at Ivy from across the food table. Daffodil dragged Ivy away before Ivy could go say hi to her. She is also compared to Heath and her aunt Petal by Daffodil later in the book.
Daisy is later mentioned to keep a diary by Daffodil when she, Ivy, Violet, Foxglove, Azalea, and Pine are searching for the stolen sand dragon treasure. Daffodil noted that Daisy wrote about "everything she eats."
- Daisy has her own diary, where she writes about everything she eats.
