The text is funny, but at the same time you're sending mixed messages. Try to be funny without doing that and it will work a lot better for you.
Also, I typically suggest calling the girl the first time you make contact, rather than texting, as calls are a lot more personal and don't get ignored as often. If you don't hear back from her via text, then give it another day and then give her a call, that way you don't come off as a crazy stalker.
A lot of guys will say that the whole rose thing is a terrible idea and if you had been trying to get with her all night, or come off as really insecure and needy, then it would be, but from the sounds of things you pulled it off quite well! Don't worry about using lines and routines, that really isn't the point. Your goal should be to understand what works with women and then you can do those things while still just being yourself.
