Pick any of these websites , pick a flower, or more, and use its/their meaning in a story about your favorite pairing.
If you want, make a story for one of your friends, use it as a Valentine's Day gift.
DCU and DCAU apply (any crossovers you want also, get creative people!)
The flower(s) you choose has to be used in the story, whether given as a gift or at least mentioned in some way.
Note: NOT restricted to just these websites, any that you find or like better, use them, if you want.
