Anne noted that her mother was like a little girl. She was vigorous in spite of being a clumsy person, and she would be enthusiastic in every situation. She was fond of boat rides and dog races, as well as oriental flower arrangements that could be found in quilt embroidery. She was a person who loved learning, had a hobbyist side to her, and liked watching romance plays. She was keen on laces and ribbons, her dresses and one-pieces mostly similar to those of princesses from fairytales. She imposed them on her daughter, as she fancied parent-children matching outfits. Clara was also noted to value the beautiful, as Anne claims that the main reason why Violet had been chosen to write the letters was because she was beautiful.

Clara was a very kind, friendly and happy person despite her frail body and short lifespan. She was also very carefree, easy-going and fast to confide in anyone. Raised as a daughter from a wealthy household, Clara was taught to be graceful and polite, traits she teaches to her daughter. She is not above scolding her daughter for something she is not supposed to do. But she has strong parental instincts and loves Anne more than anything in the world, and is deeply saddened by the fact that she has to leave Anne all alone after her death.
