Would this be too much?(preferably ladies)?

There is this girl that I have been spending a lot of time with since last nov.(on the weekends because we both work during the week) and I was thinking about trying to go ahead and step this up a level. Anyway I was thinking about buying her one of those little 3 flower bouquets and writing on one of those little cards "your eyes are amazing and if this gesture puts a smile on your face, the sun does not even need to shine because your radiance will light up the sky" and leaving it on her doorstep to surprise her when she gets home from work. I was wondering especially from some of you ladies would this be too much to let her know I like her or should I back it down a notch?
