Whatever you put on the card let it be real. By all means leave a card you don't want her to attribute your gift to someone else. Pick the flowers she likes. If she is unpacking flowers for VD on a second job she might be a little sick of seeing and smelling them.
Tell her that to you no flower could look better than her even on a bad day nor will their perfume match the aroma of your love making. But don't say that if you don't mean it for the rest of your life come heaven or hell.
