Blanche acts as co-roommate and landlord to Rose Nylund, Dorothy Zbornak, and Sophia Petrillo. Throughout the series, Rose and she are often involved in the same activities. Though she, like Dorothy and Sophia, is annoyed at times by Rose's constant storytelling, she saw her as both her best friend and a surrogate sister. Blanche has her own collection of strange stories which she shares from time to time, often tales of her rivalry with sisters Virginia and Charmaine or of the promiscuous stunts she pulled as a teenager.
