My own daughter. Blinded in a drunken rage by my late husband! Her once-beautiful eyes, pale and white as mistletoe berries. And what, my friends, is your story? Will you be found wanting when the End of Days is come, when judgement rains down upon us all? Or will you be preserved against the coming apocalypse? Do not despair! I offer a way out! There is a different path! Sweetville! Join us! Join us in this shining city on the hill!
~ Mrs. Winifred Gillyflower's sermon about Sweetville.

Mrs. Winifred Gillyflower is the main antagonist of the Doctor Who episode "The Crimson Horror". She was the founder of Sweetville. She was a prize-winning chemist and mechanical engineer. The Eleventh Doctor called her "nuts", and she referred to her own hands as "the wrong hands".

She is portrayed by British actress Diana Rigg.


Mrs. Gillyflower discovered a red leech and named it Mr. Sweet. She symbiotically lived off Mr Sweet's nectar and used his poison to create the community of Sweetville, where the best of humanity could be sealed away once a rocket inside the empty match factory that contained the poison spread the poison across the atmosphere. Mrs Gillyflower experimented on her daughter, Ada to develop an antitoxin to the red leech poison so she could survive the explosion. She lied to Ada, telling her that she was blinded by her father. She held sermons to invite people into Sweetville.

In 1893, the Eleventh Doctor and Clara entered Sweetville to investigate the "rejects" of Mrs Gillyflower's plans whose skin had turned a bright crimson. The process failed on the Doctor, but thanks to Ada and Jenny Flint, he recovered and rescued Clara from the poison-induced stasis. The Doctor confronted Mrs Gillyflower and she revealed her plan. Clara stopped the rocket from being fired, but Mrs Gillyflower held Ada hostage and ran to the secondary firing mechanism. When the rocket was launched, Jenny and Madame Vastra had already removed the poison from it. Mrs Gillyflower threatened to shoot the Doctor and his friends anyway, but Strax shot at her, and she fell to her death. In her final moments, Mrs Gillyflower begged her daughter for forgiveness, but Ada refused, to which Mrs Gillyflower expressed pride.
