Is it creepy to send a girl flowers with barely knowing her?

A girl, that was in my high school class, has a birthday coming up. I like this girl and she did some weird stuff towards me while we were in school. they didn't involve me personally, but they seemed pointed towards me.

Anyways since I like this girl, I was wondering if it would be creepy to send her flowers for her birthday. it would have a card saying "Happy birthday, may greatness find you in all your endevours" or something like that. it would also say sincerely my name and on the back my phone number.

Here is where the creepy part comes in, even though girl has made things towards me without her thinking I have acknowledged it, she and I really never had a discussion at all. well except for freshman year when we would talk all the time in one class we had. But all this time I never got her number or address.

That's where I think she might get freaked out, I have her address in a student phone book, but if I did send it would that be considered creepy?
