I am looking for a romance novel I read some time ago about a girl who is abadoned by her mother as a little girl and raised by the ex-boyfriend of her mother whom she left her with. It's years later and the man's daughter has arranged a convenient marriage with a wealthy man but bails out at the last minute and leave it up to the girl to tell the man. The man is desperite for a wife so he asked the girl to become his wife for a price. Fyi the girl is also a gardener.
