Whats a Good Gift? (Girls Please Help!?

Me and my girlfriend have just started going out. Before she was my best friend and we have known each other for a while. I'm a real southern boy and I have no idea what to get her. I just wanted to give her a random surprise. Girls can you please help me? I was thinking on flowers....or is that to cheesy? And I know I cant get her anything to flashy because she will think that's not like me. Help?
