Should I get a coworker just a sympathy card or something else?

I have a coworker whose mom recently passed. Her and I have become pretty close and she has helped me with things, so I'm thinking that next time I go to work and see her to give her a "sorry for your loss" card. Is there anything else I should bring or would that be enough? If it matters, I'm male, but her and I are just friends nonetheless.

A card would be a nice thing to do. But get a simply one.

A sympathy card would be really nice & appreciated. That will be enough to show you care.
