I know sage and rosemary are the perfect companions but I haven't heard it being companions for other vegetables. A quick search on google shows me that broccoli, cauliflower, beans, cabbage, and carrots are helped by sage but it shouldn't be planted near cucumbers, onions or rue.

thanks takadi, an answer is always welcome. I decided to keep sage out of veggie garden this year. Until I know more, this is my plan.
