Role in the plotHer Barrier (pocket dimension in which she resides) and her minions are first seen in Episode 1, menacing Madoka before getting dispatched by Mami. The witch herself appears in episode two, where her Witch's Kiss causes a woman to attempt suicide by jumping from the window of a tenement. The woman is then rescued by Mami. Mami, Madoka, and Sayaka find the barrier of the witch, and after destroying some minions, Mami is able to dispatch her.
"The rose garden witch with a distrustful nature. She holds roses dearer than anything else. She expends all of her power for the sake of beautiful roses. Despite stealing the life-force of humans who wander into her barrier to give to her roses, she loathes the thought of them trampling the inside of her barrier."
Like all witches, Gertrud can cast a "Witch's Kiss" upon mortals, causing them to fall into despair and commit suicide.
Inside her barrier, Gertrud is not a very powerful witch, but she can prove a challenge. When challenged, she tries to escape attacks while her tiny minions change into rose vines in order to entrap the intruder. When she successfully traps the interloper, she attacks, using thorny scissor-tipped vines to mangle her victim to pieces.
