Her debut appearance was in "Make Way for Miss Nettle" as the new enchanted gardening teacher. As part of an after school program, Sofia, James and Prince Desmond stay to learn how to grow magic plants. Miss Nettle then leaves the students alone so she can search for Flora, Fauna and Merryweather's spell book. Sofia runs after her to return her glove.
The fairies catch her looking for the spell book in their office and confront her. She then traps them in a magic bubble and continues looking for the book, Sofia as seen her trap them and she, James, and Desmond found the spell book before Nettle does.
The bad fairy then confronts them and demands the spell book. She then offers a deal after they refuse; they give her the spell book and she'll let the fairies go. The children agree, but Nettle then goes back on her word and decides to free the fairies after she's learned all their spells. Sofia, Desmond, and James get the book back from her by using a magic flower, the Laughing Lily.
The three free the fairies from their bubble. Then Flora, Fauna, Merryweather, and the children go back to the greenhouse and demand Miss Nettle to leave. She then refuses and threatens to put them all in another magic bubble, Desmond manages to take her wand from her but ends up in a bubble. Flora then frees him and tells Miss Nettle to leave now and never return.
Nettle returns disguised as Sascha the Sorceress in "The Enchanted Feast", claiming to show her respects for King Roland before the Tri-Kingdom Feast, and has a rose companion attached on her arm, called Rosey. She showers the royal family with gifts, but Sofia has suspicions about her, but everyone else dismisses her misgivings. Fortunately, after the amulet summons Snow White, Sofia learns to trust her instincts and goes to Cedric, and they team up to defeat Nettle. In defeating her, Sofia shows her wits have grown and how much she has become in tune with the Amulet.
She returns in the episode "The Secret Library: Olaf and the Tale of Miss Nettle". Sofia read in her Secret Library that Miss Nettle had been stealing all the Snowdrop Flowers in the Kingdom of Freezenburg and Sofia set out to stop her with help from Olaf the Snowman. Miss Nettle explained to the princess and the snowman that she is the creator of the Snowdrop and that the royal gardener of Freezenburg was the one who stole it from her in the first place. Sofia reported this to Princess Hildegard and King Henrik. After informing their subjects that Miss Nettle created the Snowdrop, they honored their winter festival to her, much to the fairy's delight.
