As explained by Hugh in Hollow City, Fiona was once was a refugee from Ireland who grew food for her village during the Great Famine (also referred to as the Irish Potato famine) of the 1840s. Despite Fiona's kindness, she was driven out of her village after being accused of witchcraft. Hugh explains that Fiona is physically able to speak, but that the "things she witnessed in the famine were so horrible that they stole her voice away." This indicated that Fiona is suffering from a condition such as Post Traumatic Stress Disorder (PTSD) or selective mutism. (However, she does end up speaking a couple of sentences in the first book, with what is described as a thick Irish accent.) It is unknown if Fiona’s parents were peculiar as well, but it is suggested they are either dead or did not raise her.
Fiona is introduced in Chapter 6 when Jacob observes a girl "in her late teens" and "wild looking" approaching a group of children who had gotten their ball stuck in a giant topiary centaur after Olive had failed to retrieve it. She is seen wrapping her arm around the centaur's tail and, in deep concentration, gets the centaur's hand and arm to move and retrieve the ball from its own chest. In the chapter during the changeover, Jacob notices a topiary of Michelangelo's fresco of Adam from Sixtine chapel with two gardenias for eyes. Spotting Fiona, he asked if she was responsible for growing it, to which she nods.
Fiona is next seen in Chapter 7 during the performance of "Miss Peregrine and her peculiar children" when Fiona appears, and Jacob is first learned of her name by Emma. On stage she stands with planters and conducts "Flight of the Bumblebee" with daisies. (A video of the song being performed can be seen under "Other Facts") Hugh also joins her performance when his bees pollinate the flowers Fiona had grown.
Emma shows Jacob Fiona's show card and tells him that they'd worked hard on her outfit. Jacob asks
if she was supposed to look like a homeless farmer, to which Emma tells him she is supposed to look "natural, like a savage person" and that they call her "Jill of the Jungle". Emma also confirms that she's actually from Ireland, not the jungle. It's also stated that Fiona can grow bushes, flowers, vegetables, and sometimes whole trees. Emma also explains about "Jill and the Beanstalk", a game the children play where they grab onto saplings and see how high Fiona can grow them.
Later in Chapter 8, Emma runs into her and Hugh "snogging each other's faces off in the garden."
"Miss Peregrine" (really Caul) rode in Fiona's hair when the children headed back to the house in Chapter 11.
During Victor's burial, she recreated the destroyed topiary of Adam over Victor's grave using some shrubs and vines.
It is revealed that she took a pot of wormy garden dirt with her when the children left their destroyed loop, which she kept pressed between her knees on the boat she was in. Upon arriving at land, Fiona scoops up and rolls some pebbles over her tongue, as if, Jacob narrates, "she needed all five senses to convince herself she wasn't dreaming." Later, she and Horace are sent to find wood. They don't bring back any, although they did find balloons searching for the children.
She later uses her peculiarity to grow a shelter in the forest for everyone, and when they settle down for the night she entangles with Hugh.
At the menagerie of peculiar animals, Fiona watches the sick Claire when everyone else goes to see the peculiar animal cemetery. She then volunteers to stay behind to look after Claire. She and Hugh share a private goodbye before he and the others leave, growing a rosebush with roses for Hugh's bees to pollinate. She embraces him and whispers something to him, to which he whispers something back before they find everyone watching them and Hugh quickly cuts the goodbye short.
During the wights' attack on Miss Wren's loop, Fiona fell down a cliff during the battle (later Miss Peregrine would say that Fiona was seen leaping off). At the time it was unknown if she had survived the fall, but Hugh believed that the greenery had possibly cushioned her landing. And Hugh needs her alive, or else he'll only have a wonderful and valid one-winged bee who happens to have a name - Henry (which Hugh loves and supports), and the love of his life would be gone.

Fiona was mentioned by Hugh when he was offended by Jacob accidentally leaving her out when he said that "everyone" was there. He, out of everyone, still believed that Fiona was alive.
She was mentioned again in Chapter Seven when Emma and Jacob asked their friends who wanted to come with them to deliver the packages for their mission, Hugh said that he would come, but he had his own mission (searching the Panloopticon for Fiona). Jacob promises that they would keep a lookout for her on their travels.
Fiona was mentioned for a third time in Chapter 12 when the children who had stayed behind at Jacob's house called those on the mission, and Hugh asked whether they had heard any news of Fiona. Emma promises him they will keep asking everywhere they go. After hanging up, Enoch says that Fiona was a wonderful and sweet girl, but she is dead and it isn't their fault if Hugh can't accept that. Bronwyn says that they still should have asked, and all of them (except Enoch) agree that they would ask from then on and say that they did right by Hugh if it turned out that Fiona really was dead.
Fiona was mentioned when Hugh had another outburst about everyone not caring about finding Fiona. After he goes out of the room, Horace reveals that he had had a dream about Fiona being on a bus. They agree not to tell Hugh, who would have them searching every bus in Britain.
Eventually, she is revealed to be alive in this book. She had not died when she fell from the cliff. At one point she was taken to America and the wights cut out her tongue, as the tongue of a seedsprout was an ingredient they needed for a potion to bring Caul back from the collapsed loop he was imprisoned in. She was placed under the control of an ambro addict, but the connection wavered on a bus after Fiona had been forced to kidnap a girl named Ellery. In an escape attempt, she causes an accident by wrapping the tires of the bus with vines. She also gives Ellery dog roses, which confirm to the peculiars that she is alive because dog roses are her special flower and she would even sometimes grow them without meaning to back in the loop.
After Hugh follows a trail of dog roses to her in the dead-risers' loop, Fiona later attacks Jacob, Hugh and Noor during battle while under the control of the ambro addict, despite Hugh's attempts to reason with her. She binds her friends with her vines, but the control wavers after Noor attacks the ambro addict. Fiona continues to strangle them after the addict is given more ambro. Jacob manages to free himself and has a surviving hollow kill the addict, thus freeing Fiona from the addict's control. After the battle, Hugh scoops her into his arms and carries her by himself, refusing to accept help. Atop Gravehill, Hugh is persuaded to let the ymbrynes examine her, where she reveals that the wights had cut out her tongue. She is then taken back to Devil's Acre where she is treated by Rafael.
Fiona's first appearance in the graphic novel is when Jake first arrives at the children's home and Fiona is with her plants. There is later a picture of her at the peculiars' show, with caption as "Girl of the Jungle." She is later shown holding hands with Hugh when they find Jake and Emma to tell them about Miss Avocet.
In Hollow City, after the peculiars reach the mainland, she goes with Horace to find wood and later grows them all a shelter. Reaching Miss Wren's menagerie, she holds Claire in her arms as the others talk, and stays behind to look after Claire. Sometime later in the graphic novel, Caul tells the peculiars that his men had paid a visit to the menagerie (by which time Fiona had probably already fallen from the cliff).
Fiona is described as looking to be in her late teens, with a wild looking appearance and mussy, dark hair that resemble dreadlocks. In the movie adaption, her appearance is drastically altered. She looks to be in her pre-teens with dirty-blonde braids; as opposed to her beggar look in the novel. She apparently has seeds in her hair.
Hugh and Fiona are what one would call 'soul mates'. Not only do they get along, but their peculiarities are quite similar. Hugh's bees pollinate Fiona's flowers. Hugh is heart broken when he hears the horrible truth that Fiona fell off of a cliff. Everyone tells him that she is dead but he still has hope.
In Hollow City, Hugh is visibly saddened when Fiona volunteers to stay back with Claire in Miss Wren's Menagerie. The two share in an affectionate goodbye, with Fiona growing roses between them for Hugh's bees to pollinate. When they turn and catch the others staring at them, Hugh sheepishly cuts the goodbye short.
Their relationship is an example of dramatic irony due to the joint connection between their abilities. Fiona posesses the ability to produce flowers (along with other vegetation) which attract bees (Hugh's ability to contain and control them with his body and mind).
Also in Hollow City, Hugh reveals that he met Fiona after she was chased out of her village and fell asleep in a field of flowers. He discovered her while he was taking his bees there to pollinate.
Near to the conclusion of Library of Souls, Hugh refuses to believe that Fiona had perished during her fight with the Wights at the menagerie. He clings to the hope that she is still alive and wandering in nature. He hopes to find her and believes that someday, she'll just turn up. The loss had impacted him much but he was still very hopeful of seeing her again when some are doubtful. Such is the hope of true love.
They are reunited again in The Conference of the Birds.
- Fiona is from Ireland.
- She is described as 'wild-looking' in the books. However, this is contrasted in the film adaptation.
- Fiona and Hugh were suggested to be dating, with Hugh being the most emotional of the possible death of Fiona, and the two being the closest. Fiona frequently allowed Hugh’s bees to pollinate her flowers, making them a perfect and sweet match. They met when Hugh found Fiona sleeping in a field of flowers.
- Unlike the book, the movie Fiona is eager and compliment, clean, and speaks. This is probably to avoid the dark history of Fiona in such a light hearted movie.
- She can speak in emergencies (books).
- Fiona's name means "white' or fair"; it is also derived from an element meaning "vine". It is a popular Irish name as well.
- Her special flower is the dog rose. She would grow them back in the loop, and sometimes without even meaning to as they would pop up behind her where she walked.
- Everything she grows is forever attracted to her, inching towards her when her back is turned.
