Petunia

Biodata

Power Progression

Petunia’s documented development consists of awakening her magic and acquiring practical magical knowledge, rather than named power ranks.

Background / History

Childhood and Lily’s Illness

Petunia grows up in the Evans family and attends Cokeworth Public Primary School with her younger sister, Lily. At ten, she discovers Lily unconscious with a dangerously high fever after receiving no answer at her bedroom door. She immediately calls their parents, enabling them to take Lily to a clinic. Although jealous of the attention Lily receives, Petunia fears losing her and later admits how badly the discovery frightened her 1 2.

Their parents’ favoritism repeatedly hurts Petunia, particularly when Mrs. Evans assumes that she should set aside her own interests to accompany Lily. Lily helps ease this resentment by explicitly telling their mother that Petunia should not always have to give way simply because she is older 2.

Discovering Magic

The sisters once planned to attend Winchester College together. Learning that Lily can instead enter Hogwarts makes Petunia fear that their shared future has disappeared. Her envy concerns both Lily’s special abilities and the prospect of being left behind while her sister enters another world 4.

Petunia initially dislikes Severus Snape, whose repeated descriptions of wizarding life emphasize her apparent exclusion. Nevertheless, curiosity leads her to read his spellbook alongside Lily. That evening, overwhelmed by jealousy during another display of Lily’s magic, Petunia accidentally levitates her own teacup. Lily embraces her in celebration, and their parents discover that both daughters are witches 5 6.

Hogwarts

Petunia receives her acceptance letter on her eleventh birthday, July 30, and immediately replies by owl. A visiting professor takes her and her parents to Diagon Alley for supplies. Before departing in September, she gives Lily an owl, having bought one for each sister so they can correspond during their year apart 7.

Sorted into Gryffindor, Petunia returns at Christmas with magical sweets and stories about school. She tells Lily that she values Gryffindor’s courage and passion but wants her sister to choose whichever house suits her best. Before Lily starts Hogwarts, Petunia spends much of the summer tutoring her in first-year material 8 10.

Once both sisters attend Hogwarts, their differing timetables limit their time together, so they arrange library study sessions. Petunia continues studying ahead and places among the top three students in her year 17 29 33.

Tales of Blossoms

Petunia helps Lily sell repackaged snacks and search for premises before the first Tales of Blossoms shop opens. As the business expands, she becomes involved in its finances 5 28.

Lily later insists that Petunia accept fifteen percent of the profits. Initially reluctant to receive the money, Petunia takes responsibility for helping manage the accounts and opens her own Gringotts vault. The sisters also review monthly turnover together 28 33.

Parallel-World Counterpart

During Lily’s displacement into Harry’s timeline, an older Petunia returns from shopping to find a twelve- or thirteen-year-old Lily lying on her sofa. She is shocked because, in that world, her sister has been dead for more than a decade. Harry is living in the same household on Privet Drive; Lily recognizes him, apologizes to Petunia, and takes him out of the house 34 35.

This encounter involves Petunia’s counterpart in another timeline, not an established future of the Gryffindor student 35 38.

Appearance

• Hair: Long, light blond 17.
• Eyes: Light brown 17.
• Features: Soft and delicate; she bears little resemblance to Lily’s red-haired, green-eyed appearance 17.
• Dress and grooming: Carefully arranged hair and coordinated clothing. For the family’s London outing, she selects matching apricot-white outfits for herself and Lily and wears her own hair in an elaborate updo 50.

Personality

Petunia is affectionate and protective, but initially sensitive to being overlooked. Her jealousy coexists with deep love for Lily: even while resenting their parents’ unequal attention, she prays that her sister will survive her fever. Discovering her own magic relieves her fear of exclusion, and Hogwarts helps her become more confident and willing to support Lily’s independent choices 1 6 8.

She is exceptionally diligent, orderly, and ambitious. During her first year, she wakes her roommates at seven to prevent lateness; later, she studies third-year textbooks while still in her second year. When her parents suggest that she studies too much, she argues that ambition is necessary, and they stop interfering with her pace 18 29 49.

Her protectiveness can become judgmental. She distrusts Snape partly because of his appearance, his home at Spinner’s End, and his Slytherin affiliation. She also recognizes his possessive attitude toward Lily and urges her sister not to encourage romantic expectations she does not share. Despite asking pointed questions about Lily’s relationships, she sometimes deliberately refrains from prying 6 13 34 38 47.

Abilities & Skills

Magic and Spellwork

• Wandless levitation: Her first magical manifestation lifts a water-filled porcelain teacup and moves it according to her attention 6.
• Academic foundations: Understands first-year magical theory well enough to tutor Lily systematically 10.
• Transfiguration practice: Keeps detailed notes on errors and corrective work. One recorded attempt to turn a cat into a glove leaves some tail fur unchanged 42.
• Elective studies: Chooses Divination, Arithmancy, and Ancient Runes 42.

Potions and Magical Safety

• Identifies that a difference of 0.2 ounces of unicorn ash can cause mild hallucinations in the healing-potion formulation under discussion 48.
• Advises storing that potion in a ceramic bottle away from light, rather than a metal container 48.
• Warns Lily against deliberately exhausting her magic, citing a book’s warning that doing so can damage a developing magic nexus and potentially leave a young wizard a Squib 46.

Accounting

• Helps maintain Tales of Blossoms’ accounts and reviews its monthly turnover with Lily 28 33.
• Handles the sustained, sedentary bookkeeping work that Lily is happy to delegate 28.

Baking and Hairstyling

• Bakes cookies that Lily enthusiastically praises; the sisters also decorate cakes together 2 3 34.
• Regularly styles Lily’s hair before leaving for Hogwarts and later creates a low Roman bun for their London outing 17 50.

Equipment / Items

• Wand — Purchased in Diagon Alley before her first Hogwarts term and initially kept in a wooden box; its specifications are not stated 7.

• Gringotts vault — Opened by the time she accepts a share of Tales of Blossoms’ profits 28.

Relationships

• Mr. and Mrs. Evans — Parents. Their early favoritism toward Lily causes resentment, but they later take pride in both daughters’ magic and academic success 2 6 33.
• Severus Snape — Lily’s childhood friend and Potions partner. Mutual distrust persists, though Petunia gives him a Christmas gift and can cooperate with him on technical potion discussions 5 7 28 48.
• James Potter — Initially considers him foolish and advises Lily to avoid him. His courteous behavior when visiting the Evans home improves her opinion, though she remains concerned that Lily is too young to date 20 38 48.
• Hestia Jones — Hogwarts roommate and study companion 17 18.
• Emmeline Vance — Hogwarts roommate 17.
