There's a slew of nice things to say with other flowers, and they're just as nice to receive. The daisy will compliment your valentine's beauty , while the elegant cala lily tops that by celebrating your lover's splendid beauty. You can only send a lilac once since it goes to your first love.
Gardenia is for the scared or the shy, since it expresses secret untold love.
Violets express your affection. Mock her vanity by giving narcissus, the flower of self-love. Let him have it with a petunia, which expresses anger and resentment. It's okay when your valentine flirts with you, but when it's with another, give a dandelion picked from the sidewalk. Perhaps too much beauty brings on haughtiness and even false appearances.
