Willow has green eyes and brown, curly hair that is of a medium length. She is fairly short for an eleven year old and has bright freckles that run up and down her arms. She has light skin that tans (and burns) easily during summertime and she typically wears green colored clothing.

Willow is smart and loves to always discover new things. She enjoys finding creative outlets and can usually be found reading. She is a good friend to all and always wants to support others. To some wizards and witches she may seem shy, but around her closest friends she is very outgoing and funny.

Coming from a wizarding family, Willow, along with her parents and her siblings, have been exposed to magic for a long time. She also owns a crup because even though they aren't necessarily typical pets, she has always loved their attitudes. Her grandparents were muggles so even though both of her parents are wizards, she still knows a little bit about the muggle communities.

Willow's first instance of magic was when she was 4 as she was walking and suddenly became a few inches to her right. She was so astonished that she didn't even mention it to her parents for a couple of days. When she finally told them, they gave her a chocolate frog in celebration.
