My male friend will give my mom flowers is that normal?

So I have a friend from Poland, and he will visit Indonesia in June and he said "you can ask me everything so I can bring so many sweets for you and I'll give your mom flowers if you invite me to your house" what does that mean? Why did he say he will give my mom flowers? Is that a culture thing or?
