About:

Professor Pomona Sprout (b. 15 May) was a British witch who worked as Head of Hufflepuff House and Head of the Herbology department at Hogwarts School of Witchcraft and Wizardry. She attended the school in her youth, where she was Sorted into Hufflepuff and excelled at Herbology. Some time after her graduation, Sprout returned to Hogwarts to teach. Professor Sprout opposed Lord Voldemort during the Second Wizarding War. In 1993, she grew the Mandrakes that would later be used in the Mandrake Restorative Draught to cure those who were petrified by Slytherin's Monster. She also opposed Dolores Umbridge and her tyranny over the school in the 1995-1996 school year, which the rest of the staff were happy to join her in doing, voted for the school to remain open after the Battle of the Astronomy Tower, and assisted in ousting Severus Snape in 1998. Sprout took a group of students to the battlements during the Battle of Hogwarts and threw Devil's Snare and various other dangerous plants onto the invading Death Eaters. She ultimately survived the War. By 2014, Neville Longbottom taught Herbology, either alongside her or as a replacement.
As the Herbology teacher, Professor Sprout was in charge of doctoring the damaged Whomping Willow by wrapping bandages around the broken branches after Harry Potter and Ron Weasley drove a bewitched car into it. On the first day of term, Gilderoy Lockhart, the new Defence Against the Dark Arts teacher, gave her useless pointers and arrogantly made out that he was a better Herbologist than her, which made her look distinctly cross and not at all her usual cheerful self. She was further irritated when Lockhart took Harry out of the lesson to speak to him, rudely closing the door in her face before she could make her opinion known. That day she taught her second years how to re-pot a new growth of Mandrake, whilst also warning them about the teething Venomous Tentacula, giving the plant in question a sharp slap to make it withdraw the long feelers it had been inching over her shoulder.This lesson and the Mandrakes would later prove to be very useful.
Professor Sprout was noted to be very cheerful, positive, and loyal,but was also very professional and just and would chide her students if necessary. Thus, Sprout possessed all of the virtues and aspects belonging to Hufflepuff House. She was kind and nurturing to the students, and surely encouraged Neville Longbottom's penchant for Herbology because he was anxious to show her his Mimbulus Mimbletonia. Sprout was also the most maternal of all the Heads of House, an example being when she calmed and got all of the students back to bed after the Battle of the Astronomy Tower.
