Daisy is full of life and always smiling, despite picking up her husband's bad habits of sleeping until noon and watching television all day. She persists in trying to get her apathetic husband to have sex with her, and tries to share romantic moments with him, however her efforts always fail as Onslow prefers to drink beer and watch "racing on the telly". As a result Daisy tends to lose herself in romantic novels. Onslow and Daisy have one daughter, Stephanie (who has a daughter called Kylie), and only appears in the final episode of series one.
Daisy's care-free, dirt-infested way of living is condemned by her elder sister Hyacinth, nevertheless it's Hyacinth Daisy always turns to, when worried about Onslow, Rose, or her senile father who frequently causes embarrassing problems that Hyacinth has to always solve. Daisy, like Hyacinth, has to help deal with their father's constant shenanigans, such as getting engaged to a succession of different women. Often he sneaks out without anyone noticing and Daisy must track him down. She pushes frequently reluctant Onslow in dealing with her father.
It is briefly mentioned in series four, that Daisy is a Liverpool football club supporter, and once went with her uncle to the games. Her support for Liverpool F.C. caused a huge problem with Onslow when they first met, because she did not reveal her allegiance until the wedding night. The football club which Onslow supports is unnamed, but since Onslow is a Scouser himself, it is presumably Everton.
